There is a 60% to 80% chance of seeing them.If you're lucky, you can spend time watching them up close as they're cleaned.Other highlights are fusiliers and migratory fish heading towards them.

At over 4m, the manta rays here are huge, and bigger than those in Japan. During high season,mantas can be seen dancing energetically together or meeting whale sharks,all on one dive.This is one of the main sites for dive cruises. When bigger species appear, please remember the three principles: don't chase, don't touch and don't panic.
