Adventure tips

Protect the reefUse reef-safe sunscreen and avoid standing on or touching corals during snorkels to preserve fragile marine life.

Bring a waterproof caseNight snorkeling and sunset photos are best with a dry phone or camera—bring a waterproof case or housing.

Watch the tide scheduleSome sandbanks and island crossings are accessible only at low tide—ask your guide about timing to plan beach walks.

Hydrate and layerCarry a refillable water bottle and a lightweight wind layer for the return—sea breezes cool quickly after sunset.

Recommended gear

Reef-safe sunscreen: Protects your skin while minimizing damage to coral and marine life.
Mask and snorkel (or mask if you prefer rental): A well-fitting mask improves underwater visibility and comfort during two snorkel sessions.
Waterproof phone case or camera: Allows you to capture daytime reef life and the night snorkel without risking damage.
Water shoes or reef shoes: Useful for rocky shore entries and walking on sandbars at low tide.
