Select participants and date
The morning opens with a short taxi ride from the cruise pier as seawarm air carries the low-lying scent of salt and peat. You shoulder a light kayak, slide off a modest dock and are immediately framed by a green cathedral of mangrove roots—tangled, dark, and alive. Guides give a quick paddling demo, then you ease into the water, the blade cutting through lagoon glass while birds wheel overhead. The kayak thread is narrow at times, a corridor where the mangroves lean across the water and the light drowns to emerald.

Adventure Tips
Bring reef-safe sunscreen
Apply high-SPF, reef-safe sunscreen before the tour and reapply as directed to protect coral and skin.
Secure your mask and loose items
Use a mask strap and stow phones in waterproof cases or lockers provided to avoid losses during paddling or snorkeling.
Hydrate and snack beforehand
Carry a small water bottle; the tour provides water but pre-hydrating helps prevent fatigue in the tropical heat.
Take motion-sickness meds if needed
If you get seasick on taxis or in chop, take medication an hour before pickup to avoid discomfort.
