Bring reef-safe sunscreen
Apply and reapply biodegradable sunscreen before entering the water to protect coral and maintain visibility for everyone.
Secure a snug mask
A well-fitting snorkel mask prevents leaks and lets you relax; disposable rental masks are provided but personal ones avoid fogging.
Hydrate and pace yourself
Unlimited water is provided on board, but drink early and often—salt, sun and snorkeling are dehydrating.
Respect the reef
Do not touch sculptures or coral; currents and fins can damage fragile growth and disturb wildlife.
