Nice short climb from the Aulne River (50m) up to 150m. Good asphalt and less traffic than down on the D-791 along the river bank.

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.

Old Quimerc'h Church (Saint-Pierre): It was built in the first half of the 16th century and "abandoned" at the end of the 19th century. In front of the church is a beautiful meadow with a table for resting. Worth seeing.

Church of SANT-SERVAIS Impressive ensemble consisting of church, ossuary (now museum) and adjoining triumphal arch. The church also reveals numerous original carpentry works with decorations, such as the theatricality of the interior or the literally fantastic stonework that adorns the façade.

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.

This chapel is dedicated to Saint-Claude, the 7th century bishop of Besançon. From the chapel, there is a view of the mouth of the Aulne and a glimpse of the Menez-Hom mountains. The 16th century building with a Latin cross plan consists of a short nave, a large transept and a chevet "Beaumanoir" of 1574. The bell tower with ornamental openings is crowned by a dome topped by a lantern. Some parts of the ancient sculptures recall a previous cult practiced on this site. In 1968, the azure ceiling was replaced by lacquered paneling and the interior plaster was removed to reveal the stones. The chapel is currently open every Sunday afternoon.
