Megalithic culture and nature give Monteneuf two distinctive themes for an exploration. The Site mégalithique des Pierres Droites is a large complex of rows and groups of menhirs. The Réserve naturelle régionale des Landes de Monteneuf, in turn, is a protected refuge for fauna and flora. To plan your visit, consider whether you want to focus on archaeological sites, engaging interpretation or the landscape.
Megaliths and archaeological sites
Excavations at the Site mégalithique des Pierres Droites, conducted since 1989, have identified more than 420 megaliths across an area of 7.5 hectares. The stones are arranged in rows and groups. The site’s local history of discovery also includes the discovery of menhirs near the Monteneuf–Guer road after the 1976 fires.
A different arrangement can be seen at the Archéosite de Brocéliande: 42 menhirs stand upright and aligned there, while almost 400 more stones are scattered among the heather and gorse. A covered gallery is located at Loge Morinais. In the Oyon valley stands the Tombeau des Rochettes, a Bronze Age burial mound. These different forms—aligned stones, scattered blocks, a gallery and a burial mound—offer several concrete ways to explore Monteneuf’s archaeological heritage.
Educational trail and seasonal activities
The Sentier de découverte des Menhirs de Monteneuf is 1.5 kilometres long and features illustrated panels and frescoes. The educational trail includes full-scale reconstructions of a Neolithic house and a workshop for making menhirs. The route therefore combines explanatory displays with reconstructed buildings. The trail is free and open year-round; check the latest access information before your visit.
The Menhirs de Monteneuf site also offers hands-on activities, including pottery, making a prehistoric ornament and learning how to move a menhir. Activities may vary by season. If you would like to take part in one, check in advance which options are available during your travel dates.
Natural landscapes and route choices
The Landes de Monteneuf landscape encompasses meadows, wet and peaty heathland, and deciduous and coniferous forests. The Réserve naturelle régionale is home to 382 plant species and 180 animal species. The natural environment can be explored through its varied landscapes and the diversity of species recorded there—as a focus in its own right alongside megalithic culture.
The 14-kilometre Boucle des mégalithes is described as a walking route through the countryside, forest and history. Local conditions may change, so it is advisable to check the latest information before setting out. The “Landes et Menhirs à Monteneuf” cycle route is another option: the Destination Brocéliande 2026 outdoor map lists a distance of 35 kilometres, an approximate duration of 3 hours and 30 minutes, and a “challenging” difficulty level. Information may be revised in later editions, so it is worth checking the current map when planning. The two routes therefore differ both in mode of travel and in the planning details explicitly provided.
Another specifically named destination is Étang du Chaperon Rouge, reached by the Circuit du Chaperon Rouge.
