Late afternoon light slices across limestone karsts as participants are gathered in Cat Ba Town and driven to Beo Harbour. The boat ride through the Cai Beo floating village feels quiet and deliberate—nets pulled by local fishermen, wooden houses drifting on the tide—until the shore at Van Boi opens into a long, low beach where kayaks wait.

Bring quick-drain footwear
Water shoes or sturdy sandals protect feet during launches and rocky beach landings and dry quickly after paddling.

Keep lights dim or off
Turn off headlamps and phones during viewing to preserve night vision and maximize plankton visibility.

If you’re prone to seasickness, take measures before the boat ride; the crossing and rocking during transfers can provoke nausea.
