The Jura Crest Trail (GTJ / GR509)

The Grande Traversée du Jura (GTJ / GR509) is a premier 400km long-distance trail snaking through the gentle, forested mountains along the French-Swiss border. Unlike the high-alpine peaks of the Alps, the Jura is characterized by vast limestone plateaus, dense spruce forests, and rolling sub-alpine meadows. The route is a contemplative journey through a 'Nordic' landscape, offering silence, deep isolation, and breathtaking views over Lake Geneva to the Mont Blanc massif. It is an accessible yet physically demanding thru-hike that showcases a unique mountain culture defined by isolated dairy farms and ancient spruce woods.

This is Stage 1 of the world-famous Alpe-Adria-Trail. Starting at the dramatic high-alpine amphitheater of the Kaiser-Franz-Josefs-Höhe (2,369m), the trail drops roughly 1,000 meters of descent into the legendary mountaineering village of Heiligenblut. You traverse the moraines of the Pasterze glacier, cross the dramatic turquoise Sandersee and Margaritzen reservoirs, and follow the Briccius trail past ancient chapels. The scenery transitions from raw, glacial desolation to the lush, flower-filled meadows of the Möll valley.
