Roche Perfia, Mountain summit in Haute-Savoie, France.

Roche Perfia is a mountain summit in the Aravis Range in Haute-Savoie, reaching approximately 2,500 meters in elevation. The peak is composed of sedimentary rock that forms its characteristic rocky structure.

Roche Perfia, at 2,499 m, belongs to the Aravis Range in Haute-Savoie, not the Bornes Massif. The French Wikipedia article records no founding date or climbing history for the summit itself; its documented historical detail is the neighbouring Trou de la Mouche, a natural arch on the path between the combe de Paccaly and the combe du Grand Crêt, below the Paré de Joux (2,383 m).

The name Perfia is local to the Aravis Range, and the summit stands on the ridge above the combe de Paccaly and the combe du Grand Crêt. Between Roche Perfia and the Paré de Joux (2,383 m) to its north-west, the Trou de la Mouche, a natural rock arch, is crossed by the path linking the two combes.

The summit is accessible via several hiking trails that begin from various starting points in the area. In winter months, visitors should expect more challenging conditions and bring appropriate equipment.

Northwest of the summit, the ridge drops toward the combe de Paccaly and the combe du Grand Crêt. Between the two combes stands the Paré de Joux (2,383 m), and the path linking them passes through the Trou de la Mouche, a natural rock arch.
