The Doubs River in France meanders for over 450 kilometres (280 mi) from its karst source in the Upper Jura to its confluence with the Saône, forming an impressive natural landscape. It serves as the border between Switzerland and France for a significant stretch, before gracefully curving through Swiss territory and flowing back into France.

On this hike, you’ll delve into the heart of the valley, staying close to the Doubs’ banks. In this sparsely populated region, nature is the master painter. The verdant hues of the forest blend with the turquoise blue of the river and the luminous white rock formations. The Doubs forms an idyllic scene, ever-present, and provides a backdrop of soothing, rippling sounds. Reservoirs intersperse with rapids and waterfalls, offering ideal spots for some refreshing summer swims.

If you like eating fish, this Tour is a culinary delight. Excellent restaurants dot the route, serving predominantly trout in various delectable ways. With a bit of luck, you might even encounter a genuine local zebra trout with its characteristic stripes. Pike and grayling are also commonly caught, while the strictly protected Roi du Doubs (Rhône nerd) hopefully remains undisturbed in the water. It's advisable to steer clear of frog legs, as they often come from illegal wild catches or overseas.

The four stages of this long-distance hike are relatively short, ranging from 13 to 21 kilometres (8 to 13 mi). There are no long, steep climbs. At the end of each stage, you'll find overnight accommodation and a nearby bus stop. The starting point in Les Brenets and the endpoint in Saint-Ursanne are easily accessible by train. Hence, I’d recommend this adventure for less experienced long-distance hikers. However, a degree of sure-footedness is crucial on the often narrow, natural paths.

Get ready for a relaxed Tour filled with captivating impressions and experiences along the Doubs. You’ll remember this wonderful region for a long time to come.
