Soi Sim is about 8.7 ha, located in the west of Halong Bay, about 12 km from Bai Chay tourist port (Halong city), about 700m from Ti Top Island. The island is a primeval forest with many kinds of plants, many of which are endemic, valued and characteristic of the Ha Long Bay ecosystem. Local people said, because on the island grew a lot of sim trees so the island should be called Soi Sim.
