Kangaroo Island, Australia
Why now: The 38-mile Kangaroo Island Wilderness Trail opened to the public in October linking three nature reserves in the southwestern corner of this flora- and fauna-rich island near Adelaide. This splits the journey up into five days by overnighting at the four designated campgrounds along the way.
What to see: You can search for Australia's most curious creature at the Platypus Waterholes, stare off into the sea at Cape Younghusband, and dive into the subterranean world at Kelly Hill Caves. The trail also provides access to some of the island's most iconic landmarks, including the geologically bizarre Admirals Arch and Remarkable Rocks.
