Tech Fun Dives around Bali: The Bali 30m to 60m best dive spots for technical diving (Open-Circuit and CCR diving)

Join us to visit the best and most exciting technical dive sites in Bali. Come to dive on Bali’s deep and untouched dive sites that only technical divers can reach. Our very experienced technical Dive Masters and Tech Diving Instructors can guide you around Bali in all technical diving configurations available: Twinset, Tech Sidemount, CCR, and even with Technical DPV.

The reefs around Bali are very famous and beautiful in the shallow, but the real magic happens once you drop below 30 meters. For certified technical divers, Bali gives you access to deep drop-offs, nice wrecks like the USAT Liberty and the Boga in Kubu, and in the deeper water where the water is a bit colder, we can often find some bigger pelagic, our favorite is the Mola-Mola Sunfish.

We can guide you all around Bali in an Open Circuit or Close Circuit Rebreather. Our Bali Technical diving trips are built for divers who want to see more, dive longer, and have more fun. We will bring you to the spots that recreational divers can’t reach. In deeper water, visibility is better, the reefs are quieter, and we can see larger marine life. Also, technical diving is the best way to find the legendary Mola-Mola Sunfish in Bali.

We provide everything you need to do safe and conservative decompression dives in Bali. Our gas fills come from a reputable, high-standard station with strict filtration. From clean air and custom helium mixes to high-oxygen stages up to 100%, you can count on dry, quality gas for every dive. We handle the logistics and the gas blending so you can focus on the dive and the fun, knowing your run times and gas switches are perfectly planned, the gases are properly sorted, and all technical details are fully covered.

Technical diving in Tulamben: Amazing Coral Reefs & Walls

Tech Diving at the Tulamben Drop-Off

We enter the water from the shore. We start the tech dive in a little bay and then head toward the drop-off, keeping the reef on our right shoulder. The coral wall starts at 16 meters and goes down to 60 meters. When we find the wall, we go straight down along the vertical and colorful coral wall of Tulamben.

We stay between 40 and 60 meters, depending on the dive plan. The wall is made of a lava flow covered in coral. The black volcanic sand contrasts with big, colorful gorgonian fans and huge sponges. We look for schools of fish, barracudas, octopuses, macro life, and sharks.

When the deep part of the dive is complete, we ascend along the colorful coral reef to complete decompression as effectively as possible. This is a nice and easy tech dive, and the conditions are always good here. It is a must-do tech dive in Tulamben.

Tech Diving at Batu Kelebit

We conduct this technical dive along a profound coral slope. To reach the site, we use a jukung (a local outrigger), which allows us to surface whenever necessary and simplifies dive logistics.

The reef here appears to descend infinitely into the depths, with the seafloor remaining well out of sight. The 45m–60m zone is the primary area of interest; here, we frequently observe cruising sharks, barracuda, and the elusive Mola-Mola.

Once the planned bottom time is complete, the ascent follows the coral slope upward. Decompression is spent exploring a colorful, shallow coral garden teeming with life. This stage of the dive is perfect for spotting nudibranchs, crabs, and scorpionfish among the rich coral formations.

Batu Kelebit is an impressive technical site where the conditions are typically calm and easy, making it an excellent choice for deep exploration.

Tech diving on Batu Nitti

Technical diving along a deep volcanic slope, ideal for dives within the 40 to 60 m range. The coral reel and the colors are stunning. The dark sand helps us find small macro stuff, but you should also keep an eye out for big fish in the deep water, like sharks and mola-molas.

It’s a very quiet dive site with great diving conditions. Technical diving gives you more time at depth, so you aren’t rushing. You can slowly hunt for small stuff and keep an eye out for big fish at the same time.”

Tech diving at Sidem

This tech dive site in Tulamben features steep walls of old lava flows, all covered in very colorful and very alive coral. It’s a perfect place for deep tech dives down to 40 to 60 m because you can reach parts of the reef that recreational divers never see. It is an easy and accessible dive site, making it a great site for testing your gear and practicing decompression diving in a very beautiful and safe technical underwater environment.

Tech diving at Segara (The 5 Fingers)

Tech diving along five lava flows from 40 to 60 meters, covered in rich coral. It feels like dropping into infinity. It’s a quiet place where tech divers can stay down longer to see the bigger stuff like sharks, turtles, and mola-mola Sunfish. It is an impressive dive spot for practicing technical navigation, using the five coral fingers to orient ourselves along the reef. On the deeper side, we keep an eye out for pelagics.

Technical diving in Kubu: The Boga Wreck, the Canyon and Batu Ringgit

Tech diving on the Boga Wreck

The Boga wreck in Kubu is a great option for technical divers who want to explore a deep and intact wreck. It sits on a sloping coral reef from 18 meters down to about 38 meters, making the bottom section perfect for practicing decompression dives. On the back of the wreck at 50m, there is a big hole we call “the Fish Tank” for tech divers who want to go a bit deeper. On the Boga wreck itself, you can see a big steering wheel, the best place for a photo and even an army 4×4 in the lower deck. Because it’s deeper than other wrecks in Bali, we generally see fewer divers around. It’s an easy entry from the beach, and looking at the propeller at 38m is a great experience.

Tech diving on the Canyon

The Canyon: The Canyon is a unique site that starts at 15 meters deep and runs perpendicular to the reef, dropping into the deep for as long as the eye can see. It is a wide channel made of black volcanic sand, with coral walls on either side about 2 to 4 meters high and 10 to 15 meters wide.

Along the way, you’ll see big gorgonians, schools of fish, and a lot of healthy coral. The sea life here is very abundant. For technical divers, we usually dive to depths of 40 to 60 meters to enjoy all the canyon can offer. Once we reach our target depth, we turn left and swim toward the Boga wreck, where we begin our ascent. It is a long, interesting, and complete technical dive that lets you see two of Kubu’s best spots in a single dive.

Tech Diving at Batu Ringgit

Batu Ringgit is an excellent spot to practice tech diving. We start from the shore with a nice and easy sandy slope entry, and an easy way to get ready.

We keep the reef on our left shoulder and follow the slope until we find the stunning coral drop-off. This is a tech dive site that lets us go as deep as we want, but we generally stay between 40 and 60 meters. The site consists of large volcanic ridges with giant pinnacles, or steps.

The reef is very rich; you can see massive gorgonians and huge sponges. Visibility is generally very good, and the current is mostly slow or mild. In the deeper parts, we look for sharks, groups of tuna, schools of barracuda, and occasionally a Mola-mola being cleaned in the freshwater thermocline.

On your way back up for decompression, the shallower sandy slopes are famous for rare nudibranchs, mantis shrimp, frogfish, and anemones. The local fish and crabs give you plenty to look at during your stops.

Technical diving in Amed: The Jemeluk Walls & The Pyramids

Tech diving at Jemeluk Wall (Right side):

Jemeluk Wall (Right Side) is famous for its steep walls and deep coral formations. On the right side of the bay, there is a very beautiful coral wall full of life, with schools of fish swimming all around.

In tech diving, when we find the wall, we dive along it as it goes directly down to 40 meters. We then follow the edge slowly down to a maximum of 50 meters. When the deep part of the dive is finished, we ascend to the coral plateau at the top to do our decompression requirements. This plateau is a very rich and colorful coral garden, which makes the deco time much more interesting.

Tech diving at Jemeluk wall left and the pyramids:

This is a great technical dive on the left side of Jemeluk. It is best done with a DPV, but if not, we use a jukung (a small local fishing boat) at the surface for assistance.

We start the dive from the shore at Jemeluk Bay and head left to find the coral wall. Here, you can see great coral formations, big gorgonians, and impressive sponges. We follow the wall down to 40 or 50 meters. When our bottom time is finished, we ascend to the Pyramids, which are right beside the wall in shallower water.

There are about 25 pyramids, artificial reefs made of large metal blocks. These pyramids are completely covered in hard and soft coral. It is a beautiful sight, full of sea life, schools of fish, and special critters. It’s the perfect place to finish your dive and do your decompression obligations.

Technical diving in Padang Bai: Special Critters Paradise. Explore more to see more.

Technical dives in Padang Bai are dedicated to the “long search” (20m–40m) for rare species.

Tech diving at Blue Lagoon and Blue Lagoon Wall (Turtle Neck)

We call the Blue Lagoon Wall “Turtle Neck” because the rock formation, which is the dive site, resembles a turtle’s head and back.

We will start our tech dive from the mooring line. We will first go down to 12 meters to find the slope where the treasures are hidden. This is where we will start the search for special species such as shorty dragonets, hornet ghost pipefish, frogfish, leaf scorpionfish, and many nudibranchs. We will follow the slope to the Blue Lagoon Wall, where we will descend to 30-40m. At the bottom of the wall, we will look for seahorses, cuttlefish, Rhinopias, mantis shrimps, and much more…

When the allowed bottom time is finished, we will ascend along the wall and enter Blue Lagoon to do decompression requirements on a beautiful coral garden full of sea life.

Tech diving at Shark Point (Tanjung Sari)

We will start our tech dive from Blue Lagoon and head to the right of the bay to reach Shark Point. It is a very nice exploration. We swim around multiple coral pinnacles, then cross a coral plateau with soft and table corals where we can spot sea turtles, octopuses, and stingrays.

Then we will reach Shark Point, an area made of rock formations. There is a patch of sand where the white-tip reef sharks are lying down, resting. We can also see some black and brown bamboo sharks hiding under the coral in the area.

After the sharks, we will continue down to 45 meters on a coral slope full of sea life. We often see other reef sharks swimming around in that place, and there is always a big school of batfish (Platax) in the area; we also see big tunas passing by. After the deep part of the dive, we will follow the coral slope back to the surface to complete our decompression obligation. We recommend doing that dive using technical DPV as the dive site is very big.

Tech diving at the Jepun Wreck and Reef

If you want to do a technical dive around Padang Bai but encounter current, or if conditions change during the second dive, the best option is a nice, long drift dive at the Jepun wreck and reef. We do not go deeper than 30 meters, allowing for a long bottom time and plenty of exploration. This is great fun.

We will start the dive from a mooring line near the Jepun Wreck, a charming small steel fishing trawler intentionally sunk to create an artificial reef. It rests at 18 meters and is full of macro critters like frogfish, nudibranchs, ornate ghost pipefish, leaf scorpionfish, schools of glassfish, moray eels, porcupinefish, and some stingrays in the sand.

After the wreck, we will drift along the reef at a maximum depth of 30 meters to look for sharks and turtles, enjoy schools of fish, and then ascend to complete the decompression requirements inside the bay near Turtle Neck (Blue Lagoon wall).

Technical diving in Candidasa: Massive Walls & Shark Caves

Tech Diving at Gili Tepekong

Gili Tepekong is an amazing and very impressive dive spot for technical diving. It is essential to know how to manage current issues, but there is always a good place to hide and find safety. Understanding the diving conditions is important for organizing an enjoyable tech dive here.

We start the dive in front of the large East Wall. We drop to 13 meters, then swim along the wall with our right shoulders toward the reef, looking for anemones, table coral, scorpionfish, nudibranchs, and cuttlefish. After swimming for 10 minutes, we reach the entrance to the “passage,” a horizontal tunnel that descends from 16m to 28m.

The exit is located exactly in the middle of the deep wall that we will explore during the second part of the dive. Coming out of the passage, we continue descending to 40m with the wall on our right shoulder. Here, we find a patch of sand where we normally spot white-tip reef sharks, cuttlefish, and turtles.

From there, we will dive further into a deep coral plateau ranging from 40m to 55m. During the season, this is the best place to spot the famous Mola mola; you can see up to 5 there. When the deep portion of the dive is finished, we head back through the tunnel to our starting point to complete all decompression requirements.

Tech Diving at Gili Mimpang

Technical diving at Gili Mimpang is a great option to see Mola mola, white-tip reef sharks, turtles, and huge schools of fish, with big trevally hunting. The coral reef is alive, covered with anthias and great macro critters. You can see three small islands or large rocks on the surface, but it looks like one big block underwater.

We start the dive in front of the rock to the west. We descend to 15 meters and follow the slope, with the reef on our left shoulder, until we reach a large coral formation in the shape of a mushroom. We will see beautiful orange soft coral, big sponges, a school of sweetlips, and big pufferfish and surgeonfish hiding inside.

After checking the coral formation, we descend the slope to 25 meters to look for resting sharks on the bottom. We will enjoy that coral slope for a moment until we reach the end. The slope then becomes a wall, and we turn left. It is now a wall dive where we can stay at 40 to 50 meters. The wall is covered with coral and abundant sea life.

After the wall, we reach the other side of the island. There is a big plateau with an edge where the Mola mola like to come to get cleaned. When the bottom time is finished, we go up the slope to a stunning coral garden to complete our decompression requirements.

Tech Diving at Gili Biaha

The visible part of Gili Biaha is like the tip of an iceberg. While the rock at the surface appears small, the coral walls are massive and perfect for technical diving. From the side, Gili Biaha resembles a croissant; we start the tech dive in the center of this crescent.

We begin the dive in the blue and swim toward the wall. We reach the wall at a depth of 10 meters to start the first part of the dive. Keeping the wall on the left shoulder at 10 meters, we swim along until we find the entrance to the Gili Biaha Shark Cave. Inside this large cave, we can see white-tip reef sharks, lobsters, fluorescent fish, schools of glassfish, and much more.

After visiting Gili Biaha shark cave, we begin the deep portion of the tech dive. We descend along the wall with the wall on our left shoulder to depths of 40 to 50 meters until we reach the edge of the island, where we may encounter current. At that point, we turn and keep the wall on the right shoulder. We then explore the deep section until our bottom time is finished. In the depths, we look for sharks, schools of fish, and Mola-mola during the season (from June to October).

We then ascend and complete our decompression obligations as we zigzag along the rich coral walls. During the ascent, we look for frogfish, scorpionfish, octopus, cuttlefish, very rare nudibranchs, turtles, and beautiful anemones with their anemonefish and anemone crabs.

Technical diving in Nusa Penida: Drift Dives, Manta Rays and Mola-Mola Hunting

We can do tech dives all along the North side at the dive sites named Buyuk, Sental, Pura Ped, and SD Point. All of those dive spots are situated along the same reef, which is five kilometers long and is the best place to do nice, long tech drift dives in Nusa Penida.

We have to check the current direction first to make sure we have enough distance for the drift. We generally drift at about 30 meters deep, and we watch the blue and the deep for Mola-Mola, sharks, big tuna, and trevally. When we spot something nice, we go down to 40–50 meters to see it. The Mola-Mola likes to get cleaned along that slope in deep water between 35 and 50 meters. By tech diving, we are increasing our chances of spotting the fabulous and very rare Mola-Mola sunfish.

When the bottom time is finished, we ascend along the prestigious coral wall and complete the decompression obligation on the stunning, colorful coral reef. We will be looking for turtles, frogfish, and schools of fish. Thousands of damselfish swim over the top of the hard coral, there are anemones everywhere, and the live coral is very impressive.

Tech Diving at Crystal Bay

This dive site needs to be done at the right time. We must check the tide tables and enter the water at the correct moment. It is also important to check the surface conditions. We recommend using a technical DPV, as the diving conditions can be unpredictable and change quickly. Having a DPV can help the tech team avoid aborting the dive.

We start our tech dive inside Crystal Bay, then find the slope and keep it on the right shoulder. We swim along the slope at 25 meters deep, looking for sea snakes, turtles, cuttlefish, and schools of butterflyfish. Then we find a crack in the slope where we like to hide if the current is coming into the bay. We can follow the crack down to 40 meters and wait for the Mola-Mola. Inside the crack (a small wall), we can see big lionfish, Wobbegong sharks, octopus, and schools of sweetlips.

If conditions are good, we continue the dive down a huge slope to 40 or 50 meters. At the bottom of the slope, there is an edge or a step; the sand begins at 60 meters below that step. We also have a deep rock on the sand, parallel to the slope, where the Mola-Mola likes to get cleaned. The top of that rock is at 45 meters. The Mola likes to show up at different places along the slope between 30 and 50 meters, and particularly likes to get cleaned on the deep edge at 40 to 50 meters. When we have finished our planned bottom time, we ascend along the slope and return to the bay to complete our decompression obligation.

Tech Diving at Blue Corner

This is one of the best places to spot the Mola-Mola. We recommend using a technical DPV to increase the chances of having a successful tech dive.

We will start the dive with a drift toward the wall. It is important to be 100% ready before entering the water to save time at the surface and start the tech dive quickly. As soon as we start the dive, we have to swim down to 15 meters and start drifting toward the wall at “Blue Corner.” During the drift, we will look for turtles, tuna, very healthy coral, trevally, and schools of fish. At the end of the drift, we will see the big wall starting at 18 meters. At that point, it is important to swim a bit harder to reach the wall and hide behind it to avoid being swept away by the current.

Behind the wall, the current will stop, and we will be at 30 meters. We will be looking for Mola-Mola, marble rays, thresher sharks, and eagle rays playing at the top of the wall. We will follow the wall down to 50 meters to look for Mola-Mola. When the planned bottom time is finished, we ascend to the top of the wall at 18 meters, then swim inside the calm bay behind Blue Corner. The bay is a huge coral garden, very colorful and full of sea life and turtles. It is the perfect place to complete the decompression obligation.

Tech Diving at Manta Point Walls

We will start the tech dive at the Manta Ray cleaning station to ensure we get to see manta rays. Then, we will dive on the coral plateau where we will look for black and brown banded bamboo sharks, frogfish, mantis shrimp, octopus, schools of fish, and more manta rays coming very close.

At the end of the sloping plateau, we will find a small wall running from 25 to 35 meters, where Mola-Mola like to come to get cleaned. At the foot of the wall, at 35 meters, we can see many stingrays, one above the other, hiding in the sand; we can also see small caves where bamboo sharks and lobsters like to hide. After visiting the first wall, we will keep the reef on our right shoulder and swim toward the second wall. Both walls are quite similar; each is a coral plateau surrounded by a wall. These two walls are good spots to see the Mola-Mola getting cleaned. This is a nice place to do a tech dive if the current is too strong at other dive sites around Nusa Penida on that day.
