How to Hike The 66 du Doubs

Switzerland is a hiker’s paradise. Its breathtaking scenery, pristine trails, and diverse landscapes lure hikers from around the world. While most visitors flock to more well-known destinations such as Zermatt, there are several lesser-known trails that are just as beautiful, if not more so. And one of those is The 66 du Doubs. This stunning three to four-day trek winds through the Doubs Natural Regional Park in Switzerland’s magnificent Jura region. Here you find unspoiled landscapes, warm-hearted locals, and tranquility that can’t be found elsewhere.

Unfortunately, before I set out on my adventure, I found little to no information about The 66 du Doubs. So, I’ve put together a complete list of everything you need to know about this epic hike to help you plan your trip.

What is The 66 du Doubs?

The 66 du Doubs is a three to four-day circular trek that begins and ends in Saint Ursanne, Switzerland. Over the course of this hike, you’ll pass villages with less than fifty inhabitants, farmlands brimming with life, and lush green forests. It’s a chance to take a break from the constant hustle and bustle of modern life and breathe crisp clean air that is void of car exhaust. Since Jura is a relatively remote region in northwestern Switzerland, few tourists ever make it this way. So, if you’re looking for solitude, this is the hike for you!
