Labuan Cermin Lake
Danau Labuan Cermin
The “Mirror Lake,” with fresh water on top and seawater below. It is so clear that it looks like a mirror, and boats seem to float in midair.
Labuan Cermin Lake lies in the Biduk-Biduk area of southern Berau Regency. Its water is a mix of freshwater from the mountains and seawater seeping in from underground. The two layers separate by density. The upper freshwater layer is crystal clear, so you can see the white sand and aquatic plants on the bottom directly. When you enter the water, you can feel the change in temperature and saltiness. From the village at the lake's mouth, a small boat takes about 10 minutes to reach the lake, where you can swim, snorkel and dive. From Tanjung Redeb, the drive takes about 6–7 hours by road, or you can charter a boat from Derawan. You usually need to spend the night in Biduk-Biduk. The lake is often visited together with Biduk-Biduk Beach and Teluk Sulaiman.
