Ulong Sand Bar Dive Site

Site Overview

Ulong Sand Bar, within the Ulong Island & Ulong Channel of Palau, is one of the region's most rewarding dive sites and a highlight of any Micronesian diving trip. A serene shallow sand bar that is a haven for garden eels, pipefish, and the occasional resting leopard shark. Geographically the site features sandbar and slope formations built from sand and coral substrate, dropping from a shallow top of around 4 metres to a maximum depth of about 18 metres, with an average working depth near 10 metres. Visibility is typically excellent, ranging from 15 to 35 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Garden Eel (Heteroconger hassi), Leopard Shark (Stegostoma tigrinum), Pipefish (Corythoichthys schultzi), Blue-spotted Stingray (Neotrygon kuhlii), Cleaner Wrasse (Labroides dimidiatus), alongside dense reef fish, invertebrates, and the soft and hard corals that blanket the reef. The mix of nutrient-rich currents and Palau's protected status makes Ulong Sand Bar one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Ulong Sand Bar is best enjoyed as part of a boat programme out of Koror, and it rewards wide-angle photographers, naturalists, and adrenaline-seeking drift divers alike. The Palau Protected Areas Network helps keep the reef pristine, so divers are asked to maintain perfect buoyancy and respect the fragile coral at all times.
