Cat Ba Island
Situated 50km east of Hai Phong, Cat Ba is the largest of the 366 islands in the Cat Ba Archipelago. Named a UNESCO Biosphere Reserve in 2004, the island has an impressive national park that houses a small population of langurs, an endangered monkey found only on Cat Ba. If you don’t suffer from a fear of heights, climb up to the park’s observation tower, but you have been warned: much of the trail involves climbing metal ladders bolted to steep rock faces. With sandy beaches, the same dramatic landscape as Halong Bay and a small city with enough restaurants and shopping to keep you occupied, this island has it all.
