What to Expect from the Itinerary

The tour begins at Kayak Village, where guides gather everyone for a quick briefing. Here, they explain basic paddling techniques, rules of the water, and the importance of protecting the lagoon’s environment. This initial intro sets the tone for a respectful and safe adventure.
Once equipped, you’ll launch your kayak from a hidden mangrove opening at the northern end of the beach.

The journey through the mangroves is both scenic and calming, with the dark water contrasting against the dense green of the mangrove roots—a peaceful, almost meditative experience.
As you enter the lagoon, your guides will gather the group for a short educational talk about the ecosystem, highlighting the flora, fauna, and sea life that inhabit this delicate environment. They also share historical information about the bay, enriching your understanding of why this place is so treasured.
The highlight of the night is when, as you paddle in the lagoon, you’ll observe the bioluminescent organisms—tiny creatures that emit a gentle, shimmering glow when disturbed. The glow is often described as magical, with reviews quoting the “sparkling water” and “incredible natural phenomenon.” Note that the level of bioluminescence can vary depending on climatological factors and the health of the ecosystem.
