This section is quite unusual and very nice on the descent with this half turn (even three-quarter turn) to go back under this bridge.

Beautiful trail, but be careful, some sections are treacherous with all those logs and crooked trunks. They've really damaged our forest, thank you, Europe and the ONF (National Forestry Office).

A small observation deck at the top of the religious site. Unfortunately, the surrounding area would benefit from being cleared of trees to fully appreciate the view, as the panorama is limited by vegetation. It's best to visit in winter to be less bothered by the foliage.
