Tête des Fétoules, Mountain summit in Isère, France

Tête des Fétoules is a 3,459-metre summit in the Massif des Écrins, in the French Alps. It rises in two points: a lower, narrow left point of dark rock and a broad, rounded central snow peak whose left flank is a smooth snow slope. To the right the ridge falls away in near-vertical rock walls where snow clings in narrow gullies.

The peak was first summited on August 29, 1876, by Emmanuel Boileau de Castelnau, marking a key milestone in French Alpine exploration. This early ascent was part of the wider movement of mountain discovery that defined 19th-century alpinism.

The summit stands on the ridge separating the vallon des Étages to the east from the vallon de la Lavey to the west, alongside the tête de l'Étret. Its name, Fétoules, refers to the mountain itself rather than to any building or monument; no chapel, refuge or inscribed marker stands on the summit.

The ascent requires specialized glacier climbing equipment and takes at least two days, starting from a parking area near Refuge de La Lavey at Champhorent. The route follows the Vallon de la Lavey valley and demands altitude acclimatization and experience in alpine mountaineering.

Tête des Fétoules separates the Vallon des Étages to the east from the Vallon de la Lavey to the west, sharing that divide with the Tête de l'Étret and other summits. Its 3,459 m summit was first reached by Emmanuel Boileau de Castelnau on 29 August 1876.
