Mont Fourcat, Mountain summit in Mercus-Garrabet, France.

Mont Fourcat is a Pyrenean summit reaching 2,001 m on the boundary of Cazenave-Serres-et-Allens, Freychenet and Montferrier in Ariège. It is the first peak above 2,000 m on the main crest of the Tabe massif coming from the west, and its massive silhouette forms a cirque open to the east, widening above the Ariège valley. Grey crags and cliff bands alternate with green slopes up to the ridge.

Mont Fourcat is the first summit of the main crest of the Tabe massif to exceed 2,000 metres when coming from the west. The sources record no historical events, travellers or herders linked to the peak; its documented record is geographical, defined by its position on the crest and its isolation, more than 3 km from the nearest other 2,000-metre peak of the massif, the pic du Han (2,074 m).

The summit lies at the meeting point of three communes: Cazenave-Serres-et-Allens, Freychenet and Montferrier. Its name, Fourcat, refers to a forked or notched shape, echoed by the mountain's outline as seen from the Ariège valley. The peak marks the eastern end of the Tabe massif's main ridge.

The summit lies on the boundary of Cazenave-Serres-et-Allens, Freychenet and Montferrier, so approach routes differ by commune. The nearest other 2,000 m peak of the Tabe massif, the pic du Han (2,074 m), is more than 3 km to the south-east. The open cirque faces east above the Ariège valley, so the western slopes are the most direct line of ascent.

The summit lies exactly on the boundary of three communes: Cazenave-Serres-et-Allens, Freychenet and Montferrier. It is also the first peak of the Tabe massif's main ridge to pass 2,000 m when coming from the west, and stands more than 3 km from the next such summit, the Pic du Han (2,074 m).
