This is another of the interconnected trails in the Municipality of Toques network (PR-G 166, 167 and 168), making it possible to combine the routes.

The trail begins with a one-way section and then forms a loop. We recommend taking an anticlockwise direction for a less demanding gradient. This route shares a small section with Trail PR-G 166, before beginning the climb up to San Cidre Chapel. From this high point, there is a magnificent panoramic view of the surrounding area. From the “cruceiro” (stone cross), you can make out the unique scrubland plain that characterizes the Serra do Careón SCI.

Continue along the mountain tops towards San Xiao, a small area where you can take shelter in the shade of the English oak wood, visit San Xiao Chapel and discover Casa Grande do Herdeiro, which features all the typical elements of an ancestral home: “hórreo”
(raised granary), pigeon shed and stone wall.

Before beginning the descent back to the starting point, be sure to visit Castro de San Xiao, a perfect example of the castro type of pre- Roman fortified settlement, and explore the different parts.
