The Jurassic Coast Path

Forming the eastern end of the monumental South West Coast Path National Trail, the Jurassic Coast is England's only natural World Heritage Site. This 95-mile (153km) section stretching from Exmouth to Old Harry Rocks near Studland covers 185 million years of Earth's history in its crumbling cliffs. The trail requires punishing daily ascents and descents as it roller-coasters over dramatic headlands and plunges into secluded coves. From the stark white chalk stacks of the Isle of Purbeck to the golden sandstone cliffs of West Bay and the classic arches of Durdle Door, it is a visually spectacular, geologically significant, and physically demanding coastal trek.

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.
