Bay of Fires Lodge, Tasmania
It takes a 14-mile, two-day hike to reach this 10-room coastal hideout that was built in 1999. Everything at the lodge is sustainable, solar-powered, and eco-friendly: Green architect Ken Latona set the lodge long and low amid casuarina pines to keep all man-made presence to a minimum on this wild stretch of beach in Tasmania's Mount William National Park. Take a kayak to the unspoiled shoreline and dip into its numerous secluded coves. If you want a real escape that leaves no trace, without roughing it, then this is the place for you.
