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.

Scoresby Sund (Kangertittivaq) is not a single trail, but the world's largest fjord system—a sprawling 350km-deep maze of ice and rock in East Greenland. Exploration here is ship-based, where expedition vessels serve as mobile base camps. Each day, Zodiacs ferry you to remote shorelines like the red sandstone slopes of Røde Ø or the high ridges of Milne Land. Unlike West Greenland, there are no marked paths; you'll be walking over ancient, spongey tundra and sharp basalt scree, always accompanied by guides with polar bear deterrents. It is an experience of immense scale, where skyscraper-sized icebergs ground themselves in the deep fjords while muskoxen forage in the silent valleys.
