The hull cuts through low-slung blue, and by late morning the islands appear—broad granite shoulders rising from clear water, their white beaches flashing in the sun. On Island No. 8, the Sailing Rock juts up like a photograph waiting to happen; you can climb for a quick panorama or linger in shallow water as currents push you past coral bommies.

Bring reef-safe sunscreen
The national park restricts chemicals that harm coral—choose reef-safe sunscreen and apply before boarding to protect reefs.
Wear a snug mask
On guided snorkels, a well-fitting mask reduces leaks and lets you focus on marine life instead of clearing water.
Prep for boat motion
If you’re prone to seasickness, take medication before departure and sit mid-boat where motion is least felt.
Respect no-touch rules
Avoid touching corals or chasing wildlife—keep fins up and controlled to prevent accidental damage.
Rashguard or UV shirt
Protects skin from sun and chafing during long periods of snorkeling and boat travel.
