Bali is one of the rare places where a complete beginner and a logged-hundreds diver can have an equally good week underwater without travelling far apart. A shore-entry wreck on the north-east coast, manta cleaning stations off a neighbouring island, and wall diving inside a national park are all within a few hours of each other.
Here is what is actually worth diving in Bali, what certification you need for each, and when to come.
Where to Dive in Bali
| Site | Known for | Depth | Level |
|---|---|---|---|
| Tulamben | USAT Liberty wreck, shore entry | 5–30 m | Beginner to advanced |
| Nusa Penida · Manta Point | Reef manta cleaning station | 8–15 m | Beginner friendly |
| Nusa Penida · Crystal Bay | Mola mola in season, clear water | 10–30 m | Advanced (currents) |
| Menjangan | Wall diving, soft corals, visibility | 10–40 m | All levels |
| Amed | Calm bays, macro life, training | 5–25 m | Beginner friendly |
The USAT Liberty at Tulamben
The Liberty is the dive most people remember. It is a US Army cargo ship, torpedoed in 1942 and beached on the shore at Tulamben. It sat there for two decades until the 1963 eruption of Mount Agung shifted it off the beach and into the sea, where it now lies parallel to the shore in 5 to 30 metres of water.
What makes it unusual is the access. You walk in from a black pebble beach and the wreck begins around 30 metres out. No boat, no long surface swim. It is one of the most approachable wreck dives anywhere, which is why you will see Open Water students and photographers with thousands of dives on the same site on the same morning.
Go early. By nine in the morning it is busy, and the black sand kicked up by fins costs you the visibility that makes it worth diving.
Manta Rays at Nusa Penida
Manta Point sits off the exposed south-west coast of Nusa Penida, where reef mantas queue at cleaning stations to have parasites removed by wrasse. The encounter is shallow, often 8 to 15 metres, which means it is available to Discover Scuba divers as well as certified ones.
Two honest caveats. The crossing can be rough, and the site is exposed, so surface conditions are a real factor. And mantas are wild animals: they are resident year-round, sightings are common, but nobody can promise them. Keep a respectful distance, stay low, and do not chase. They will usually come closer if you do nothing at all.
Mola Mola: Worth Planning Around
Between roughly July and October, oceanic sunfish rise from deep water to be cleaned at sites around Nusa Penida, most famously Crystal Bay. They are extraordinary animals, some over two metres tall, and seeing one is a genuine event.
This is not a beginner dive. Crystal Bay can carry strong down-currents, and the thermoclines that bring the mola mola up also bring water at 20–24°C, cold enough to matter over a full dive. An Advanced Open Water certification and some current experience are the sensible minimum.
Which PADI Course Do You Need?
- Discover Scuba — one supervised dive, no certification required. The right choice if you want to see whether you like breathing underwater before committing. Enough for Manta Point.
- Open Water — the standard entry certification, typically three to four days. Certifies you to 18 metres and opens up Tulamben and Amed properly.
- Advanced Open Water — usually two days after Open Water. Takes you to 30 metres and covers the deep and drift skills you want for Crystal Bay and Menjangan's walls.
We run all three, and the honest advice is that most people underestimate how much better their week is with Open Water rather than a single try-dive. Three days of your trip buys you every other dive site on this page.
Diving with Fitrip means small groups, unhurried briefings and instructors who dive these sites weekly, not seasonally.
When to Dive in Bali
Diving runs year-round. Visibility is generally best in the dry season, April to October, and that window also covers both the manta peak around April and May and the mola mola season from July to October.
In the green season, runoff can soften visibility at some coastal sites, though Tulamben and Menjangan tend to hold up better than most. Water temperature sits around 27–29°C for most of the year, dropping into the low twenties at Nusa Penida during mola mola season.
How Many Days Do You Need?
A useful rule: one dive day gets you one site properly. Bali's dive sites are spread across the island, and the driving is the constraint rather than the diving.
Tulamben and Amed sit on the north-east coast, roughly two to three hours from the south. Nusa Penida requires a fast-boat crossing from Sanur, typically 30 to 45 minutes, and the sea state on that crossing is a genuine factor in the green season. Menjangan is in the far north-west, inside West Bali National Park, and is realistically an overnight trip rather than a day trip from Canggu or Ubud.
If you have three dive days, we would usually suggest one at Nusa Penida for the mantas, and two on the north-east coast covering the Liberty wreck and the surrounding reefs. If you have a week, add Menjangan and stay the night up there rather than driving four hours each way.
A Note on Surface Intervals and Flying
One piece of planning that catches people out: do not dive on the day you fly home. The standard guidance is a minimum of 18 hours between your last dive and a flight after multiple dives, and at least 12 hours after a single dive.
It is worth building this into your itinerary early rather than discovering it the evening before departure. The same applies to driving up to Kintamani or Bedugul after diving, since both sit high enough that the altitude change matters.
A Note on Diving Responsibly
Bali's reefs carry a lot of visitors. A few things make a disproportionate difference: keep your fins off the substrate, do not touch or ride anything, hold your position rather than crowding a cleaning station, and use reef-safe sunscreen or a rash guard instead. Manta cleaning stations in particular stop working if animals are approached too closely, which costs everyone the encounter.
