Saint-Maurice Church of Thônes

Highlight • Religious Site

"Thônes has preserved the appearance of a historic small town. The central square (Place Bastian) and the streets that extend from it, which are lined by numerous houses with arcaded arches, are characteristic." (Wikipedia)

Marais Pass

Highlight • Mountain Pass

The Marais pass is a rather accessible pass compared to other passes in the Aravis. Less known and therefore less frequented, this makes it a very pleasant little pass!

Col de l'Épine (947 m)

Highlight • Mountain Pass

Small, little-used pass above Marlens.
On the way down to Marlens it is really fun, fast and playful.
The ascent to the North is quite easy and gentle.
