Twin Reef is a reef dive site in Philippines Palawan, Asia.
Overview
Twin Reef is Port Barton’s headline dive — two distinct parallel coral structures a short boat ride from the village, offering an impressive diversity of healthy hard corals that double as a fish sanctuary. The shallows are immediately rewarding for beginners and snorkelers, with butterflyfish, clownfish in their anemones, and schools of reef fish darting through the coral heads in very calm, uncrowded conditions.

Marine Life
Twin Reef’s hard coral sanctuary supports an abundant and approachable reef fish community, with butterflyfish, angelfish, and parrotfish crowding the healthy coral heads and clownfish defending their anemones throughout the site. Hawksbill turtles are frequently sighted on both reef structures, and the calmer current here makes them particularly relaxed and easy to observe. Deeper along the reef slope, whitetip reef sharks occasionally rest in the sandy passages between the two coral structures.
