Cat Ba is the largest island in Halong Bay. The central hub of Cat Ba town features a chain of low-rise concrete hotels, however, the rest of the island is largely untouched; wild, rugged and jungle clad. The islands’ national park offers a range of outdoor activities, including rock climbing, kayaking, and snorkeling, as well as opportunities to experience local seafood and island village culture. With its natural beauty and relaxed atmosphere, Cat Ba Island is an ideal spot for relaxation and adventure.
