Le GR20

The GR20 is widely regarded as the most demanding long-distance trail in Europe. Stretching 180km along the jagged mountain spine of Corsica, it is a high-altitude odyssey between Calenzana in the north and Conca in the south. The route sits on the boundary between strenuous trekking and non-technical alpine scrambling, characterized by steep granite ridges, exposed chains, and the legendary Mediterranean sun. It requires not just physical endurance but a high degree of comfort with rocky, uneven terrain. Note: Compiled from public sources — not a field report.

The wild heart of the Rockies. Stretching over 1,100km from Waterton Lakes National Park to Kakwa Provincial Park, the Great Divide Trail (GDT) is a loosely connected series of trails, old forestry roads, and off-trail cross-country segments. It follows the Continental Divide, crossing between Alberta and British Columbia dozens of times. Unlike more established National Scenic Trails, the GDT is often a "choose your own adventure" experience where the path frequently vanishes into scree slopes or dense willow bushwhacks. Hikers must be prepared for extreme isolation, technical river crossings, and the relentless verticality of the Canadian Rockies.
