Sun protection is essential
Bring broad-spectrum, reef-safe sunscreen, a wide-brim hat and sunglasses — the sun reflects off water and white cliffs intensifying exposure.
Expect variable sea conditions
Morning departures are generally calmer; if you’re prone to seasickness bring medication and sit mid-boat where motion is least noticeable.
Snorkel ready
Snorkelling gear is provided but a well-fitting personal mask improves visibility and comfort in choppy water.
Footwear for rocky shores
Water shoes or sturdy sandals make beach exits and volcanic pebble landings easier and protect against hot sand and sharp pumice.
Reef-safe sunscreen
Protects skin and marine life during extended sun exposure on deck and while swimming.
