Dôme de l'Arpont, Alpine summit in Vanoise National Park, France.

The Dôme de l'Arpont is a mountain peak in the Vanoise range, a high alpine area in the French Alps. The mountain features glaciers that cover its slopes and shape the appearance of the summit throughout the year.

The mountain is part of Vanoise National Park, established in 1963 to protect this mountain area. The park's creation was an important step to preserve the region's nature for future generations.

The summit lies in the Vanoise massif of Savoie, north of the Dent Parrachée, and its name refers to the dome-like form of the top. It is a landmark on the Vanoise glacier routes, and the Refuge de l'Arpont below carries the same name.

Climbing this peak requires specialized mountaineering equipment and experience with technical climbing, so proper preparation is essential. The best time to climb is between June and September, when conditions are safest.

The Dôme de l'Arpont lies just north of the Dent Parrachée, a neighbouring summit in the same Vanoise massif. The two are often seen together on the skyline above the Arc valley, and the rounded dome contrasts with the sharper forms around it.
