The premier adventures in Lan Ha Bay
Unlike central Ha Long Bay where strict marine regulations limit where you can paddle, Lan Ha Bay offers far greater freedom for active water sports:
Kayaking: The number one must-do activity. Paddle through low arches into quiet lagoons where birds nest in cliff vegetation.
Swimming & snorkeling: Dive into clean, warm emerald water from your boat deck or lounge on natural sandy coves.
Deep water soloing: Climb vertical karst cliffs above deep water with no ropes—if you fall, you splash safely into the sea.
Bioluminescent plankton: Take a night kayak or boat tour after dark to watch the water light up with millions of sparkling blue-green bioluminescent organisms.
Floating restaurants: Dine on floating raft houses in Cai Beo, selecting live crabs, prawns, squid, and grouper straight from sea pens.
