Kīlauea Iki Trail

The Kīlauea Iki Trail on the Big Island of Hawaii offers an otherworldly experience: the chance to hike directly across a solidified, still-steaming lava lake inside a volcanic crater. In 1959, this crater erupted sustainedly, shooting fountains of lava 1,900 feet into the air and filling the basin with a fiery lake. Today, the surface has crusted over into a jagged floor of jet-black 'pahoehoe' (smooth) and 'a'a' (sharp) lava rock. The hike begins in a dense, lush, tropical rainforest of native ohia trees and giant hapu'u tree ferns along the crater's rim before plunging 400 feet down the steep walls. Hikers then follow a path marked by stone cairns ('ahu') directly across the desolate, cracked, steaming expanse of the crater floor, walking over active volcanic vents.

The Three Capes Track is a 48km point-to-point trekking route within Tasman National Park, Tasmania. Starting at the Port Arthur Historic Site with a marine transfer across the bay to Denmans Cove, the route traverses the high sea cliffs of the Tasman Peninsula. The track is highly engineered, featuring wide gravel paths and boardwalks that provide safe access to vertical dolerite columns reaching 300 meters above the Southern Ocean. Management is handled by the Tasmania Parks & Wildlife Service, with a regulated north-to-south flow. The route transitions through diverse environments including coastal heathland, dry sclerophyll forest, and temperate rainforest.
