Great Ocean Walk

The Great Ocean Walk is a 104km point-to-point coastal trekking route in Victoria, Australia. Connecting Apollo Bay to the Twelve Apostles, the trail follows the Shipwreck Coast within the Great Otway National Park. The route traverses mixed terrain including Mountain Ash forests, coastal heathland, and tidal beaches. It serves as a terrestrial alternative to the Great Ocean Road, providing access to remote cliff-top vantage points above the Southern Ocean. Surface composition consists of managed forest tracks, purpose-built boardwalks, and segments of uncompacted sand and rocky littoral platforms.

Lençóis Maranhenses is a vast field of mobile sand dunes positioned along Brazil's northeastern coast. The landscape is defined by the seasonal accumulation of rainwater in the valleys between dunes, creating thousands of clear freshwater lagoons from May through August. The 43km trekking traverse between Atins and Santo Amaro involves sustained walking across soft sand slopes and navigating between the remote Baixa Grande and Queimada dos Britos oases. The primary challenge is the combination of high thermal stress, intense solar reflection from the white sand, and the physical load of soft-substrate movement.
