Puy de la Vache and Puy de Lassolas Loop Trail

The trail features diverse volcanic terrain. You'll encounter sections with volcanic rock, scree, and solidified lava flows known as 'cheires'. A notable part includes a pozzolana quarry, described as a 'lunar landscape'. The ascent of Puy de Lassolas is very steep with rolling pouzzolane stones, while the descent from Puy de la Vache often involves wooden steps. Other parts wind through undergrowth and mixed forests. Erosion on the ridges means staying on the marked path is important.

The loop offers stunning panoramic vistas. From the summits of Puy de Lassolas and Puy de la Vache, you can enjoy expansive views of the Chaîne des Puys to the north, the Monts Dore to the south, and distant ranges like the Monts du Cantal. The distinctive 'open craters' of these two volcanoes are a key visual feature, and the volcanic rock itself presents a striking palette from red to black.

While categorized as 'moderate' for walking, the trail's characteristics make it challenging for continuous jogging, especially for beginners. The steep ascents with loose volcanic stones on Puy de Lassolas and the wooden steps on the descent from Puy de la Vache would likely interrupt a steady jogging pace. Be prepared for varied, potentially unstable surfaces and significant elevation changes.

For jogging, the Komoot data estimates the duration to be around 37 minutes for the 4.3 km loop. However, due to the challenging terrain with steep sections and loose volcanic stones, your actual time may vary significantly, especially if you need to slow down or walk parts of the route.

Parking is typically available at the Montlosier car park. However, please note that the Montlosier car park is scheduled to be closed between August 2025 and 2027 for works. Additionally, access to the summits of Puys de la Vache and Lassolas may be closed for works between spring 2026 and early 2028. Always check local signage for the most current access information.

Yes, dogs are generally permitted on the trail. However, as the trail is located within the Parc Naturel Régional des Volcans d'Auvergne, it is crucial to keep your dog on a leash at all times to protect wildlife and ensure the safety of other visitors. Please also remember to clean up after your pet.

No, there are no specific permits or entrance fees required to access this trail. It is located within the Chaîne des Puys, a UNESCO World Heritage site and part of the Parc Naturel Régional des Volcans d'Auvergne, which is freely accessible to the public. However, general regulations for natural parks apply, such as staying on marked paths and not disturbing wildlife.

Spring and autumn generally offer the most pleasant conditions with milder temperatures and beautiful scenery. Summer can be warm, so an early start is recommended. Winter conditions can make the trail more challenging due to snow and ice, especially on steep sections and exposed ridges, requiring appropriate gear and caution.

Yes, the route shares sections with several other trails. You'll find it intersects with parts of 'Le Puy de la Vache', 'De Laschamp au Lac de Servières', 'Tour des volcans et lacs d'Auvergne', 'De lacs en volcans', 'Le Puy de Vichatel', and 'Les Cheires Hautes'.

These are the youngest volcanoes in the Chaîne des Puys, estimated to be around 8,000 years old. Their unique 'open craters' were formed by continuous lava flow during their eruptions, which also created the Cheire d'Aydat. The entire route is considered an 'open book of Volcanology', showcasing various volcanic deposits and processes.

While the immediate trailhead area is primarily natural, you can find cafes and restaurants in nearby villages. The area around Lac d'Aydat, which was formed by the lava flow from these volcanoes, is a good place to look for dining options after your hike.
