Deep in the South Australian outback, just over four hours from Adelaide, Arkaba Station—a 19th-century sheep ranch turned luxury lodge—feels remote enough for most. But for an even more thorough immersion in the landscape, the 1856 homestead’s walking safaris may just be the ultimate means of getting away from it all. Guides Kat Mee and Brendon Bevan lead groups of up to eight on a four-day, 30-mile route through Flinders Ranges National Park, known for its centuries-old river red gum trees and hills covered in pompon-like golden wattle. (Your bags await each evening at camp, along with a three-course dinner and a hot outdoor shower.) Plush beds and feather duvets on open-air wooden platforms ensure a good night’s rest, although the wilderness doesn’t lack for background noise: Listen for the call of kookaburras and magpies at dawn and dusk, a kind of outback melody.
