Why dive here
With 246+ marine species recorded in the area - including blue-spotted stingrays, bull sharks, grey reef sharks, manta rays and mobula rays (devil rays) - Manta Bay offers some of Lombok & Gili Islands's richest drift diving. Water ranges 28-30°C, warmest April, May, November.
Manta Bay is exactly what it sounds like. We’ve had some truly epic manta encounters here, watching them glide through the nutrient-rich water, mouths agape, scooping up plankton. The site itself is a sloping reef that meets a shallow wall, topping out around 18 metres. It’s the kind of dive where you often feel the surge, especially closer to the cliff face, but that movement is what draws the mantas in. Our favourite way to dive Manta Bay is to find a spot with a bit of shelter from the main current and just wait. We've spent entire dives watching mantas circle and feed, sometimes coming within a few feet. Beyond the big draws, keep an eye out for whitetip reef sharks resting under ledges and plenty of reef fish like Gendarme fish darting amongst the staghorn corals. Visibility here averages around 14 metres, which is perfectly adequate for those close manta interactions. It’s an accessible site for most divers, just be prepared for some water movement.
Safety Notes
