Cairns & Port Douglas
This list sorts the reef trips out of Cairns by how you want your day to run: snorkel boats, dive boats and pontoons that suit non-swimmers. The outer reef sits about 90 minutes offshore, so every option is a full day. From November to May you’ll snorkel in a stinger suit; crews hand them out and nobody argues.
