Pic de Bonvoisin, Alpine summit in Massif des Écrins, France

Pic de Bonvoisin is a 3,480 m mountain in the Écrins massif, in the Savoie department of Auvergne-Rhône-Alpes. It is glaciated on all sides: the Glacier de Bonvoisin lies on its north slope, the Glacier des Bruyères to the east, the Glacier de Surette to the south and the Glacier de Jocelme to the west. Its summit marks the boundary between Vallouise-Pelvoux and La Chapelle-en-Valgaudémar.

The summit was first mentioned in the 1860s. The first ascent took place on 20 July 1935, and a second climb followed only after the Second World War, on 8 September 1945. The mountain has no economic or tourist development, and the easiest route starts from Vallouise along the Torrent des Bans.

The summit marks the border between Vallouise-Pelvoux and La Chapelle-en-Valgaudémar, so the two communes meet on the glacier-covered peak. Its east slope holds the highest springs of the Onde, a right tributary of the Gyronde. The mountain is neither developed for tourism nor used economically.

The easiest ascent starts from Vallouise, following the Torrent des Bans; a hiking car park lies at the trailhead, and the Refuge des Bans (2083 m) stands four kilometres further west. The summit is not developed for tourism, so the approach is on foot throughout.
