Charter a private yacht out to secluded reef sites for snorkeling and diving far from the day-tripper pontoons.
What to expect
You depart Cairns marina and cruise roughly 90 minutes to pristine outer reef locations like Michaelmas Cay or Paradise Reef. A marine biologist briefs you on the coral systems and marine life before you slip into the water. Snorkeling and introductory diving are both offered, with crew assisting nervous swimmers. Lunch is served onboard between sessions, with sun deck lounging as you cruise back.
Good to know
Book 1-2 weeks ahead in peak season; bring reef-safe sunscreen (required); Cairns port timing means confirm the return window fits your all-aboard call.
