The first time you arrive at the Blue Lagoon you notice how the water pulls the light into a color that refuses to be plain blue — it has depth, a tropical clarity that makes the lagoon look like a held breath. Your guide leads a short forested track from the parking area: palms and broadleaf trees lean over the path as if pointing toward the water, the air humid and fragrant with wet soil and salt carried from the nearby coast.

Wildlife
History
The lagoon sits along a northern coast shaped by limestone and river channels, historically used by Taíno communities and later touched by colonial-era farming and fishing economies.
Conservation
Avoid chemical sunscreens and take all trash with you; the lagoon’s health depends on reduced runoff and protection of surrounding mangroves.

Wear water shoes
Rocky shelves around jump points are slippery; closed-toe water shoes give traction both on shore and in the water.
Use the life jacket
Even confident swimmers should wear the provided life jacket around deeper sections and near the lagoon outlet.
Watch the currents
The lagoon is calm inside but the channel toward the sea can pull; follow guides’ marked swim zones and exit points.
Protect electronics
Bring a small dry bag or waterproof case for phones and cameras—splashes are common at jump platforms.
Water shoes
Provide grip on limestone and protect feet from sharp rock and coral.
