Of the 1960 islands the are dotted around its 600 square mile area, the vast majority are limestone karsts that rise up out of the water and tower above the hundreds of cruise boats that ply their trade here.
The island is in the Southwest of Halong Bay and is about 7 miles from the Tourist Wharf. It covers an area of approximately 22 acres, with a hill at either end. There are two beaches here, if you are lucky enough to get one of the Halong Bay cruises that stops off here, there are two beaches to enjoy also. The island used top be partially covered by sim trees, hence the name. There are still plenty of trees here and other lush greenery. This offers cover to a variety of bird life including Black Kites, Egrets and Herons.
The island sits just about a quarter of a mile from another famous island here, Ti Top Island. There are some resorts here and the island is being developed.

There is a population of wild monkeys on the island, these should not be approached.
