A snorkel tour with these guys based in Arcadia is a good-value way to get an appreciation of the ecology around Geoffrey Bay. Deep-water thinkers can do three-day PADI open-water courses to kick-start their scuba skills, as well as advanced courses and Yongala wreck dives for regular plungers.

If you're an experienced diver wanting to dive the Great Barrier Reef, this is one of the best deals around with two-dive trips to little-visited Lodestone Reef for $269 ($229 for snorkellers).
