Hiking in Sentier Karstique Besain: trails, map and practical info

Nice walk. Even with kids (6 and 9 years old) a very easy trip of 4.17km if you do both loops of the trail, though the 150m elevation provides a good workout. Moss everywhere turning the forest into a very fairylike environment. Deep sinkholes in the karstone rocks everywhere showcase the Jura's unique geology. Walk through what feels like the scenery of a fairytale come true. There's even a cave you can visit without the company of a guide.

It was a surreal experience. The place was covered in snow, transforming the karst landscape into a winter wonderland. The place was isolated in the afternoon with the 150m elevation making navigation more challenging in winter conditions. I would recommend a proper safety warning should be there, especially given the sinkholes and cave openings that can be hidden under snow. Beautiful but requires caution.

Lovely walk with children and very interesting karst landscape featuring limestone formations and sinkholes. Route doesn't return to car park so you'll have to walk along the road at the end, which adds about 15 minutes to your journey. The geological features make it educational for kids, though the 150m elevation gain requires some stamina. Well worth the effort for the unique Jura terrain.

Very nice walk through the forest along a number of interesting features of the local geology, with rock formations and natural caverns. It was a bit difficult to follow the track currently (early 2020) due to forest works on the parking side. The total tour takes about 1h with the 150m elevation gain. Then after crossing the road you can either go straight for another hour walk or turn left and head back direction parking. Good walking shoes highly recommended, as the terrain is rather uneven at places and can be challenging on the karst limestone.
