Diving Lembongan and Penida

The strait around Lembongan, Ceningan and Penida brings deep, cool, nutrient-rich water past healthy reefs. The result is clear water, big animals and some of the best diving near Bali. The same water movement means currents, and diving here is about respecting them.

Learning to dive

Lembongan has several dive schools that run beginner courses. Training usually starts in a pool or calm shallow water, then moves to gentle reef dives before the more demanding sites. Small groups and an instructor who knows the local currents matter more than anything else.

What you can see

• Manta rays at cleaning stations off Penida, through most of the year.
• Mola mola, the oceanic sunfish, mostly in the cooler months, roughly July to October, usually at depth. More on the mola.
• Turtles, reef sharks and big schools of fish on the drift dives.
• Coral slopes and walls along Penida's north and west coasts.

Drift diving and currents

Many sites are drift dives: you let the current carry you along the reef and the boat follows your bubbles. Done right, it's effortless and beautiful. But currents here can be strong, can run down as well as along, and can change with the tide. This is why experience levels matter for some sites, and why a good operator will change plans on the day.

Choosing a dive school

• Ask how many divers per guide, and how they match sites to experience.
• Look for surface marker buoys for every diver and oxygen on the boat.
• Trust the school that says "not today" when conditions are bad.
