World's Best Treehouse Hotels

Why It’s Unique: Hinchinbrook, a 96-acre national park with lush rainforests, rugged mountains, and coarse sandy beaches, has just one option for accommodations: the Wilderness Lodge, a secluded hideaway with 15 roomy timber treehouses, each with floor-to-ceiling glass windows, small kitchen, private balcony and bath, and easy beachfront access.

Access: Winding timber boardwalks.

What to Do: Explore one of the island’s 11 secluded beaches, and in the evening relax at the Wilderness Lodge bar.
