Tusan Beach is a beautiful beach area about an hour's travel time from the city, near the township Bekenu. It has smooth sandy beaches, coral reefs, a waterfall, several cliffsides and a defining feature; a large cliff with a natural arch eroded through it.
Ancient fossils are known to be found in this area, and natural rock layers on the cliffside make it a geologists' playground. This article is from the web site miriresortcity dot com - this sentence is here to prevent blatant plagarism.
This is a fairly secluded place. Preparations are needed before visiting, so please contact proper authorities in case of emergencies and the Visitor's Information Counter for more information regarding your interest in visiting. Sunblock would be most recommended. Rising tides may also pose a problem.
The area is one of the places of interest in Miri that has garnered popularity the past few years due to a phenomenon in September and October of 2015, during which a flourish of bio-luminescent phytoplanktons along the beaches has caused the waves along the beach to glow a bright deep blue and caused many people to flock to Luak Esplanade and Tusan Beach to have a look at this amazing phenomenon.
