Float three miles down the Martha Brae on a licensed bamboo raft, then watch the Luminous Lagoon ignite beneath your hands on an evening swim. This private half-day pairs calm river navigation with a bioluminescent night swim and local stories.
More ways to explore the area's outdoor wonders
You push off from a low wooden jetty and the Martha Brae River takes hold—its current steady, almost conversational—guiding a 30-foot bamboo raft down three miles of rainforest waterway. Overhead, the canopy parts in places to reveal shafts of sun; the guide hums old songs and names plants with a practised, dry humor. The river moves like a living map, carving limestone gullies and ferrying orchids in its wake.

Bring water shoes
Carrying sturdy water shoes with good grip makes boarding rafts and walking on slick docks much safer.
Time your visit for night light
The lagoon’s glow is best after sunset—plan to arrive with enough daylight to change and prep for the night swim.
Respect the bioluminescence
Avoid soaps, sunscreens, and heavy splashing in the lagoon; the microorganisms are sensitive and the experience is easily diminished.
Pack insect repellent
River corridors and docks can have mosquitoes at dusk—apply repellent before the evening lagoon visit.
Water shoes
Protects feet boarding rafts and walking on wet, uneven surfaces.
