Boulders is a unique dive site with dramatic rock formations. At the surface, you face a vertical stone wall and a few large boulders breaking the surface. As you descend underwater, down the slope, the site is covered with different shaped and sized boulders that look like they have rolled from the cliff and have come to rest on the slope, creating swim-throughs and caves and lots of hiding places for marine life.

The site is home to various marine life including:

• Thorny Seahorses
• Ribbon Eels
• Schools of Snappers
• Nudibranchs (various species)
• Cuttlefish
• Black Coral Formations
• Crustaceans in rock crevices

This unusual dive site doesn't sport much of the lush vegetation and colorful corals seen at other dive sites in Puerto Galera. Instead, you'll be treated to dramatic rock formations, black coral formations, schools of Snappers hovering over the reef, lots of Nudibranchs, and often Ribbon Eels and Cuttlefish. This is where we find the Thorny Seahorse, the one that doesn't need a magnifying glass to be seen unlike its pygmy counterpart. They reside in 28-30m, unfortunately hiding in the rubble, but a good dive guide will find them for you.
