Blue Hole Rock Formation
This is a unique natural attraction that is a must-see for snorkelers and divers. Keep calm and dive through San Agustin’s famous “hole dive site” in the Philippines! From the town proper, you must ride a boat for about an hour to reach the bay of Barangay Cawayan and crosses Sitio Dayundong. As you swim and descend into the hole, you will witness its rich in rare marine life and wonderful coral formations such as big fan corals. Beginners are allowed to explore this dive site freely but going beyond 30 meters in depth, requires a specialized or advanced diving license. If you’re finding an unspoiled and unexploited dive site, Blue Hole should be on your list!
