The beauty of this trip, a 28-mile route that cuts through rainforest and over 1,000-foot ridges in the wild, 3,500-foot Blue Mountains, is the access: it starts in Katoomba, just a 90-minute drive or two-hour train ride ($15.60 round-trip; cityrail.info) from Sydney. Spend the night before the trek at the Carrington Hotel, a sprawling three-story colonial affair (doubles, $130), then set off. Sydney-based outfitter Life’s an Adventure offers a guided trip with tents big enough to stand up in (from $380). Or pack your own tent and explore the stands of stringybark trees and the sandstone cliffs overlooking eucalyptus valleys yourself. Allow three days and two nights—spend one night ten miles in at the Six Foot Track Eco Lodge ($35 per person)—to reach the Jenolan Caves, a series of ancient limestone caverns. After exploring, catch a bus back to Katoomba ($40; trolleytours.com.au).
