A pretty iron bridge, built for farmers at the time. Here the path along the water was in a bad state in April 2026 (a warning was installed on one side of the section, but a detour through the forest is possible).

From the south, a short, steep climb on mostly good asphalt. Only the last 100 meters are a bit of gravel on the road. At the top, you're rewarded with a unique view over Finisterre.
