The compact island state of Tasmania, off Australia's southeastern tip, carries an outsize reputation for wilderness and untrammeled natural beauty. This leisurely four-day walk (departing daily October-April) traces the magnificent coastline known as the Bay of Fires, on the fringes of Mt. William National Park in north-eastern Tasmania. Led by friendly and knowledgable local guides, the experience immerses you in the pristine environment; highlights include traversing soft sandy beaches strewn with red-tinged boulders, exploring hidden rocky coves, and kayaking the Ansons River. And when it comes to bunking down, forget roughing it: hikers stay one night at the Forester Beach Camp, a tented camp tucked in a protected dune swale on a white-sand beach, and finish at the Bay of Fires Lodge, an award-winning hideaway with indigenous-inspired spa treatments and incredible food paired—naturally—with Tasmanian wines.
