Mont Vinaigre, Mountain summit in Var, France

Mont Vinaigre is the highest summit of the Esterel massif, reaching 614 m on the boundary of Fréjus and Les Adrets-de-l'Estérel. Cork oaks and chestnut trees once covered it; repeated forest fires left maquis scrub, with bare pale grey and yellowish rock at the top. A wooden signpost at the summit reads "MONT VINAIGRE alt" above "614 m", with the letters V, L and B stacked on its left post.

In the 18th century the mountain served as a hideout for the brigand Gaspard de Besse (1757–1781), who robbed travellers and tax officials; escaped convicts from the Toulon bagne also took refuge here. His story inspired Jean Aicard's novel Maurin des Maures. The summit area later received a heliport below the peak.

The name means "Vinegar Mount". In the 18th century the summit sheltered the brigand Gaspard de Besse (1757–1781), who robbed travellers and tax officials; his story inspired Jean Aicard's novel Maurin des Maures. Escaped convicts from the Toulon bagne also hid here.

Access is available via the DN7 road between Fréjus and Mandelieu-la-Napoule, which provides direct entry to the mountain. The site has restricted hours between 9 PM and 6 AM to protect the natural environment.

The summit holds a heliport just below the top, and an old viewing tower stands there that cannot be entered, alongside radio transmission installations. The GR 51 long-distance footpath crosses the mountain from west to east, and a second path climbs from the hamlet of Logis de Paris to the north. The paved DFCI forest track from the DN7 is closed to private vehicles at a barrier one kilometre past the Malpey forest house.
