Mont des Avaloirs, Mountain summit in Mayenne, France

Mont des Avaloirs is a summit in the Mayenne department, on the border of Orne, reaching 416 metres as the highest point of the Massif armoricain. It forms a plateau of heathland and thin meadows above the Multonne forest. A belvedere built in 1994 stands on the site, its two sloping panels carrying a 2019 mural by Seb Toussaint.

The summit lies within the Normandie-Maine Regional Natural Park, created in 1975. On 5 September 2023, UNESCO recognised the park as a global geopark. Since 25 September 2020, the site has been part of the Mont des Avaloirs regional nature reserve.

In 2019 the Franco-British artist Seb Toussaint painted a mural covering both sloping faces of the 1994 belvedere. The work is not a nature study: it belongs to his Share the Word project, in which residents choose a word for the wall. Visitors see the painted panels before entering the viewing platform.

The belvedere built in 1994 stands a short distance from a car park reached from Pré-en-Pail; a path from there leads to the Pierre au Loup site, near which the Mayenne rises in Lalacelle, Orne. The summit is a plateau of heath and thin meadows, so wear shoes suited to open ground. The climb by bike from Pré-en-Pail is nearly two kilometres long with pitches at 8%.

The summit lies within the Mont des Avaloirs Regional Nature Reserve, created on 25 September 2020. The surrounding Multonne forest and heathland belong to the Normandie-Maine Regional Natural Park, which UNESCO recognised as a global geopark on 5 September 2023. The Mayenne river rises near the Pierre au Loup site, a short walk from the belvedere car park.
