You step off the boat and the sea rearranges your plans — warm water laps around your ankles and a breeze pushes the salt through the air like an invitation. The day moves in chapters: a panoramic run past the 27 islands, a snorkel above living coral, a loud party cove, a quiet fruit-break on a pale crescent of sand, then a relaxed lunch on Playa Tranquila.

Bring reef-safe sunscreen
Protect coral by using mineral SPF and reapply sparingly; sunscreen washes off in water and impacts reefs.
Pack a small dry bag
Keep phone, ID and cash dry — a 5–10 L bag fits essentials and floats if you drop it.
Prepare for seasickness
If you’re prone to motion sickness, take medication or wear pressure bands before boarding; boat crossings can be choppy.
Cash for island vendors
Small vendors sell seafood, fruit and souvenirs; carry small bills and coins for quick purchases.
Reef-safe sunscreen
Protects skin and marine life — use mineral-based sunscreen to reduce coral impact.
Mask and snorkel
A well-fitting mask improves your snorkeling experience; rentals are often available if you don’t bring one.
Dry bag (5–10 L)
Keeps valuables, camera and extra clothes dry during boat transfers and beach stops.
Light long-sleeve rash guard
Provides sun protection and a bit of warmth in the water without overheating.
