Lost City Trek (Ciudad Perdida)

Route Typology: Guided Jungle Expedition. The Lost City Trek leads to 'Teyuna', an archaeological site of the ancient Tairona civilization built around 800 AD. Located deep in the humid heart of the Sierra Nevada de Santa Marta (a UNESCO Biosphere Reserve), the 44km route involves a cumulative vertical strain of 2,700m. The final approach requires a climb of 1,200 ancient stone steps. While the max altitude is only 1,200m, the primary challenge is the extreme tropical humidity (often 90%+) and consistent heat, paired with steep, muddy jungle ridges and river crossings.

The Wilderness Coast Walk is a remote, point-to-point coastal trek of roughly 100 km, linking the Merrica River trailhead in South East NSW (Nadgee Nature Reserve) to Mallacoota Inlet in Gippsland, Victoria (Croajingolong National Park). The route traverses expansive sand dunes, sandstone headlands, and coastal heathlands along the Tasman Sea, with optional extensions to Green Cape. Navigation relies on tidal windows and topographic cues, as much of the track is unmarked. The walk passes through critical habitats for species such as the White-bellied Sea Eagle. Permits are required from NSW National Parks & Wildlife Service and Parks Victoria.
