Daisetsuzan Grand Traverse (大雪山縦走)

The Daisetsuzan Grand Traverse is a premier high-altitude wilderness trek in Hokkaido, Japan. This approximately 55km (34 mile) north-to-south route crosses the core of Daisetsuzan National Park—the largest national park in the country. The trail traverses an expansive volcanic alpine plateau characterized by active fumaroles, subarctic meadows, and permanent snow patches. The region provides habitat for the Higuma (brown bear) and the rare pika, offering a true subarctic wilderness environment.

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.
