In a natural environment of rare beauty, a “sensitive natural area”, the cairn of Petit Mont is also a great starting point to walk around the monument, on the coastal paths, the GR34 and the surrounding beaches.
Just a 15-minute walk from Port-Crouesty, it also allows you to discover other megalithic and heritage sites of the Rhuys peninsula: Tumiac, Graniol, Bilgroix and the Domaine de Suscinio.
Composed mainly of moors, still exploited and maintained extensively until the 1950s, by traditional agriculture, the site of the petit mont evolved after the cessation of these agricultural practices.
From the 1990s to today, the part has evolved towards plum thickets. The western part is occupied by fairly stable moors because they have to adapt to marked ecological constraints (strong winds, sea spray, poor soils).
