Koh Rong Bioluminescent Swimming

Swim in glowing water. Every stroke creates swirls of blue light as bioluminescent plankton react to movement. It's like swimming through liquid stars, with wine on the beach waiting for afterwards.

Insider tips

• Best on moonless nights in dry season

• The plankton are everywhere but concentrate in calm bays

• Swim first, then wine on the beach

• Long Beach is accessible but Lonely Beach is more intense
