The mountains of O Careón form the last stretch of the
demanding Camino Primitivo before it joins the Camino
Francés to Santiago. This mountain range is of moderate
height (798 m, maximum) and the subsoil has special
characteristics which make it an area of great geological
interest in Spain.
There are an abundance of small mountain rivers which
run together into the river Furelos, the final tributary of
the Ulla. There are also numerous hill-walking routes
through the area, and even the local roads which cross
the mountains are of landscape interest.
One of the most outstanding places is the shrine of San Antolín de Toques, surrounded by the forest, or
the route to As Fervenzas (Toques), with its drop of some 40 metres beside an old mill.
