Location : Gusung Sanggalau Island, Kabupaten Berau, Kalimantan Timur, Indonesia.
After finding no luck with the manta rays at Sangkalaki Island, we shot off towards the direction of Derawan to make a brief stop at Pulau Pasir / Gusung Sanggalau Island. Gusung Sanggalau Island is very near to Derawan Island, basically is a sand bar of very fine white sand with a cute little lagoon. This island gets submerged during high tides, and will reappear when the tide is low. Nothing much to do here but still worthy of a visit.
