Morning departures for best visibility
Book an early start — calm seas and lower wind usually mean clearer snorkeling conditions and smoother boat transfers.
Use reef-safe sunscreen
Choose biodegradable, reef-safe sunscreen and reapply after swimming to protect coral and marine life.
Bring water shoes
Sharp coral and uneven entry points make thin-soled water shoes useful for beach and reef access.
Watch for changing tides
Tide and current can affect snorkeling safety and boat anchoring — listen to guides about where to enter and exit the water.
Snorkel mask (or bring your own)
A well-fitting mask improves visibility and comfort during extended surface swims.
Reef-safe sunscreen
Protects your skin and the coral ecosystem from harmful chemicals.
Water shoes
Protects feet on rocky shallows and reef edges when entering or exiting the water.
Dry bag and quick-dry towel
Keeps valuables dry on the boat and makes post-swim changes easier.
