La Roche Péréandre

La Roche Péréandre is a 39-metre granite monolith rising above the Cance valley in the commune of Roiffieux, in the Ardèche department, right on the edge of Vernosc-lès-Annonay. Protected as a classified heritage site since 1932, it remains one of the most recognisable natural landmarks in northern Ardèche.

What makes this rock special?

Roche Péréandre is a single block of granite — hence "monolith" — rising almost vertically above the Cance riverbed. It belongs to the same granite landscape found throughout northern Ardèche and the Massif Central, where solid rock outcrops break through the river valleys. A small metal cross has stood on its summit since 1930, placed there by scouts from nearby Annonay, and it is still visible from the paths below today.

The rock's name comes from an 18th-century legend. A fisherman named André, convinced a treasure lay hidden beneath the rock, dove into the Cance and discovered an underwater cave, only to be trapped there for three days as the river rose. The name "Roche Péréandre" is said to commemorate "the rock where André perished." Some accounts also point to a possible origin in the Greek "petra andros," meaning "stone of man."

What can you see there?

About 100 metres north of the rock stands a Neolithic dolmen, its entrance deliberately oriented toward Roche Péréandre. A path leading to it branches off roughly 175 metres west of the car park by the rock, making it an easy addition to a visit. The rock face itself is a well-established climbing spot: numerous routes have been bolted here, ranging from grade 4C to 7C, so climbers training on the granite wall are a common sight in season.

How do you get there?

Access is via the D371, which loops around Annonay, followed by the narrow D270 running alongside the Cance toward the Rhône valley. A small car park sits right at the base of the rock, serving both walkers and climbers. For those after a longer outing, a roughly 7.7-kilometre walking loop circles the rock and takes about two hours to complete, offering several different vantage points along the way.

When should you visit?

Spring and autumn bring the most comfortable conditions for walking and climbing, with mild Ardèche temperatures and a granite face that doesn't overheat in direct sun. In summer, an early morning visit is best before the exposed rock surfaces get too hot to handle. Because parking is limited and the access roads are narrow, arriving early is advisable on good-weather weekends.

Frequently asked questions

Is Roche Péréandre difficult to reach? Viewing the rock from the lower paths is an easy walk. Climbing the face itself, however, requires proper gear and experience, with routes ranging from grade 4C to 7C.

Can you visit the dolmen without a long hike? Yes — the dolmen sits only about 100 metres from the rock, and reaching it from the car park takes just a few minutes along a forest path.

How much time should you set aside? Walking to the rock and the dolmen takes around 30–40 minutes, while the full loop around Roche Péréandre takes roughly two hours.

Is the site suitable for families with children? The lower paths are easy and suitable for children, but climbing routes and approaches near the rock's edge require supervision given the steep granite terrain.
