History
Laguna Grande has long been an important coastal wetland for local communities; its bioluminescent bays gained conservation attention in the 20th century as tourism grew.
Conservation
Operators limit boat traffic and brief guests on low-impact behavior; avoid lotions, soaps, and litter to protect the dinoflagellates and mangrove habitat.

Bring a waterproof headlamp for boarding
A dim red or low-setting headlamp helps for launching and reading instructions without washing out night vision.
Avoid sunscreen before the tour
Oils and residues can wash off into the bay and affect water quality; use reef-safe products well before arrival.
Wear closed-toe water shoes
Expect to get wet from the waist down and walk on wet docks or mangrove roots during launch and landing.
Check moon phase when booking
New-moon or low-moon nights maximize bioluminescent visibility; bright moonlight reduces the glow.
Waterproof headlamp or small flashlight
Useful for boarding, reading safety info, and finding gear without impairing night vision.
Closed-toe water shoes
Protect feet on wet docks and mangrove roots and provide traction when entering/exiting kayaks.
Biodegradable insect repellent
Keeps bugs at bay during shore-side briefings while minimizing harm to the lagoon.
