What are the main points of interest along the way?

The highlight of the route is undoubtedly The Infernet spring, a beautiful vauclusian-type resurgence emerging from a small cave. Before reaching the source, you'll also pass a waterfall and experience the unique 'French Colorado' landscape with its striking red and ochre rock formations.

Is the trail dog-friendly?
