Tusan Beach, near Bekenu about 40 minutes south of Miri, is the most photographed stretch of coast in northern Sarawak. Its sandstone cliffs frame a long, wild beach whose icon is a sea arch shaped uncannily like a horse's head dipping to drink from the sea.
Tusan's other claim to fame arrives after dark: on some nights the surf glows an unearthly blue with bioluminescent dinoflagellates — the famous 'Blue Tears'. The display is natural and unpredictable, strongest on dark, moonless nights, and never guaranteed.
