Mont Teret, Mountain summit in Dingy-Saint-Clair, France.

Mont Téret is a rectangular limestone anticline in Haute-Savoie, rising to 1,543 metres. Its south-western and north-eastern ends are sheer cliffs above the Fier and Fillière valleys, and its southern tip forms the tower-shaped Tête à Turpin. The summit plateau is karstic, with numerous cavities known to cavers.

Mont Téret is an anticline, a fold in the rock that continues the Montagne des Frêtes beyond the cluse de la Fillière. Its rectangular mass is bounded by the valleys of the Pertuis and the Fillière and by the gorges of Ablon, and its southern end forms the tower-shaped cliff of the Tête à Turpin.

The mountain's name appears as mont Téret in French and monte Teret in Italian, reflecting its position in Haute-Savoie near the Italian-speaking Alps. The karst plateau is known to cavers, and the summit's southern end, the tête à Turpin, is a cliff with a tower-like profile that walkers can pick out from the Fier valley.

Well-marked trails begin from multiple starting points and lead upward through forests and alpine meadows to reach the top. Starting early in the day gives you enough daylight, and bringing layers is wise since weather changes quickly at this elevation.

The limestone plateau beneath the peak is pockmarked with cavities that form an extensive underground network lying just below the surface. This hidden geology surprises many hikers who explore the summit area.
