Soi Sim Island (Dao Soi Sim)

Soi Sim Island, Vietnam

The Basics

In recent years, Soi Sim has become known as a center for ecotourism, with its endemic plants and two mountain peaks drawing numerous hikers. Wooden lodges provide unique waterfront accommodation, and unspoiled beaches offer ample opportunities for swimming, sunbathing, and water sports. Few day cruises stop at the island, so if you want to visit, you’ll likely have to do so as part of an overnight or 3-day cruise. Some cruises sail past the island, while others stop for time to swim and relax on the beach or climb to the top for panoramic views over Halong Bay. It’s a good idea to double-check the exact itinerary before booking if you want to ensure a visit to the island.
