Selingan Island is one of three islands that form the Turtle Islands National Park, located approximately 40 km north of Sandakan. The beaches of Selingan, Bakungan Kecil and Gulisan Islands are nesting sites for both green and hawksbill turtles. Only Selingan is open to visitors and the island is accessed via a 1-hour speedboat ride from Sandakan.
The 8-hectare island has a range of facilities including accommodation, café, park HQ and interpretive centre. Although turtles lay eggs all year round the best time to visit Selingan is between July and October when the sea conditions are calmer and the number of turtle landings is higher. As turtle landings normally occur after dusk an overnight stay is highly recommended. In addition to having the chance of seeing turtle landings, visitors can observe park rangers collect eggs, tag turtles and release baby turtles.
