Le Grand Suchet, Volcanic mountain in Puy-de-Dôme, France.

Le Grand Suchet is a volcanic peak within the Chaîne des Puys in central France, reaching 1,231 meters in elevation. The mountain is characterized by a crater at its summit and a secondary peak of 1,199 meters, giving it a distinctive two-part geological form.

The sources record no eruption on Grand Suchet; it is an extinct pyroclastic cone of the Chaîne des Puys, built of ejected material around a barely marked summit crater at 1,231 metres. Its second, unnamed summit, the opposite crater rim, reaches 1,199 metres. The mountain lies on the territory of Ceyssat, southwest of Clermont-Ferrand, between the puy de Dôme and the puy de Côme.

The name Suchet likely relates to the neighbouring Petit Suchet, the two summits being distinguished only by size. Walkers reach the top by a dead-end path from the unnamed pass between them, climbing the eastern face. The wooded lower slopes give way to open ground near the 1,231-metre crest.

The GR 4 and GR 441 pass at the foot of the mountain, skirting it to the west and south. A connecting path uses the unnamed pass between the Grand and Petit Suchet, and from there a dead-end trail climbs to the summit via the east face. The wooded slopes give way to open ground around 1,150 metres.

The crater is barely marked: its rim forms an unnamed second summit at 1,199 m, 32 m below the main top at 1,231 m. A dead-end path from the unnamed pass between Grand and Petit Suchet climbs the eastern face to reach it.
