Great bridge, with great gravel route that runs underneath

The marked trail is rugged. Magnificent views of the Brest harbor. The Terenez port boat graveyard. Arrival at the pretty Seillou beach, opposite Landevennec.

The bridge has a separate bike path. This is lowered by approximately 1.5 m from the roadway. This reduces exposure to the wind. In addition, people with a fear of heights can cycle along the lowered section without having a view of the depths.

Belvédère de Rosnoën: a very beautiful vantage point overlooking the meanders of the Aulne River; a few benches invite you to sit down. The parking lot is a great starting point for a hike—a recommended hiking trail branches off directly from there.

Very beautiful viewpoint in the middle of the forest - just a few steps away from the main path: be sure to take a short detour.

Superb arched bridge over the Aulne, similar to the Millau viaduct in its design (same architectural firm). It was built to replace a bridge built in the 1950s, more suited to today's traffic. The construction materials (e.g. sea sand for concrete) affected its solidity.

Magnificent curved bridge nestled in the hollow of a valley!

The best photo of the bridge can (unfortunately) only be taken in the middle of the carriageway. The look of the cable construction when driving through is impressive.
