Skip the crowds entirely with a seaplane transfer over Ha Long's lesser-visited sister bay, Bai Tu Long. Land on glassy water, board a private boat, and kayak through virgin caves and floating villages that see a fraction of Ha Long's visitors.
What to expect
A 45-minute Cessna Caravan flight skims low over the limestone archipelago, giving you an unobstructed aerial view before splashing down near Vung Vieng, a centuries-old floating fishing village. A private wooden boat then escorts you through Thien Canh Son Cave, where stalactites glow amber in your torch light. Afternoons are spent swimming off a deserted white-sand beach before the seaplane whisks you back. The entire day feels like a private expedition rather than a tour.
Good to know
Seaplane terminals are at Van Don Airport, close to Cai Lan port — ideal timing from Sadek. Seaplanes require advance booking (at least 7 days); weather cancellations are possible so have a boat-only backup plan. Combine with a private speedboat for the cave segment.
