The northernmost island along the Great Barrier Reef, Lizard Island has a reputation as a classy resort island, with over 20 white sand beaches and the spectacular Coral Sea on all sides. The best time you'll have is under the water, with some of the best diving and snorkeling around. Visit Cod Hole, where travelers have been feeding the potato cod for over 20 years, or a bunch of other reef sites like Dynamite Reef, Kate's Place, Big Softie, and more. If you aren't one to indulge the first-class tourist in you, then do yourself the favor of staying in the national park campgrounds. It's roughing it a bit more, but will be more of a genuine experience. Also, while you're here, stay active on the terry firma with a climb to the island summit (Cook's Look) or the short trek from the island airstrip to Mangrove Beach (Blue Lagoon).
