Why dive here
With 82+ marine species recorded in the area - including manta rays, mobula rays (devil rays), whale sharks and pufferfish - Old Volcano offers some of Siargao's richest diving. Water ranges 27-30°C, warmest June, August, September.
The Old Volcano site in Siargao offers some interesting topography, with lava formations creating natural swim-throughs and small caves. We’ve seen plenty of reef fish here – angelfish, butterflyfish, and occasionally a passing snapper. It’s a pretty easy dive, good for newer divers or those looking for a relaxed afternoon. The currents are generally mild, making it a comfortable spot to explore.
