It’s complicated for independent travelers to get to from Vietnam’s Ninh Binh to Catba island along the southeastern edge of Halong Bay. Instead of piecing together the trip on your own, book this convenient bus and ferry transfer. Twice-daily departures mean you can fit this trip into your schedule as you see fit. Board at bus at the Tam Coc Wharf for the drive to Hai Phong province. Then, Take the Dinh Vu ferry to Cai Vieng Pier. Upon arrival, board a second bus and drive through the Catba rain forest before arriving at Cat Ba Town.
