Green Island

Compact Green Island caters to all ages. Calm, shallow water is perfect for young children, and snorkelling is beginner-friendly from the beach or jetty. Circuit the island in under an hour, or go on a glass-bottom boat trip, helmet dive, or heli flight. Day visitors can also use the resort pool. Ferries run regularly: Great Adventures (greatadventures.com.au; adult/child return $107/54) offers flexibility with multiple departures, while Ocean Free (oceanfree.com.au; adult/child $279/220) combines sailing and Pinnacle Reef snorkelling.
