Dive Site Overview
Anticipating a plunge into the Davao waters, divers often set out from Sta. Ana Wharf, embarking on a boat trip that typically lasts 30-45 minutes to reach Marirssa.
The site encompasses three distinct dive spots – Marirssa 1, 2, and 3 – all offering variations of a dramatic vertical wall, a true spectacle of marine architecture.

Divers can navigate along the reef, exploring the vibrant tapestry of soft corals, sponges, and gorgonians that cling to every surface.
Angelfish and jacks are common sights, darting among the colorful corals or schooling in the blue. Lucky divers might also spot reef sharks, including the blacktip reef shark, patrolling the deeper sections down to its maximum depth of 40 m / 131 ft.
While the site promises rewarding encounters, the possibility of strong currents means that diving with a knowledgeable guide is highly recommended to ensure a safe and controlled exploration, especially for those venturing to these advanced depths.
