Grand Assaly, Mountain summit at France-Italy border, Savoie

Grand Assaly is a mountain summit in the Alps that sits on the border between France and Italy in the Savoie region. The peak rises to about 3174 meters and offers expansive views across the alpine landscape on both sides of the frontier.

The summit lies on the Franco-Italian border between Sainte-Foy-Tarentaise in Savoie and La Thuile in the Aosta Valley. Its name comes from the Valdôtain patois arsali or ansali, meaning alisier (wild service tree), while pointe du Petit refers to the small Glacier du Petit it overlooks. The Doigt d'Assaly, a slender rock gendarme on the eastern ridge at 2,971 m, was first climbed in the 1950s by Chamonix guides.

The name Assaly comes from Valdostan patois arsali or ansali, meaning service tree (alisier); in Italian the peak is thus the "Great Service Tree". The alternative name Pointe du Petit refers to the small Glacier du Petit it overlooks, while the neighbouring Petit Assaly lies east of the Grand glacier. The pointed rock spike on the eastern ridge, the Doigt d'Assaly (2,971 m), was first climbed in the 1950s by Chamonix guides; in August 2014 slackliners rigged a roughly 40-metre highline between it and the summit ridge.

Reaching the summit requires mountaineering skills and proper gear such as ropes and ice axes in challenging conditions. Visitors should prepare for changing weather and be familiar with alpine terrain.

The eastern ridge holds the Doigt d'Assaly, a slender rock pinnacle at 2,971 m first climbed in the 1950s by Chamonix guides. In August 2014 a group of slackliners rigged a highline of about 40 m between the Doigt and the summit ridge. A three-pitch 5c climbing route also exists on the pinnacle.
