Aiguille des Arias, Alpine summit in Massif des Écrins, France.

Aiguille des Arias is a 3,403 m summit in the Écrins massif, above Saint-Christophe-en-Oisans and Valjouffrey in Isère. Its upper part is bare grey and brown rock, with a snowfield in a hollow below the peak and a sharp subsidiary ridge of dark pinnacles projecting from the face. Lower slopes carry patches of green vegetation.

The sources record no first-ascent date for the Aiguille des Arias. The usual route to its summit is the Bec de Canard–Arias traverse, graded D in the French alpine scale, linking the neighbouring Bec du Canard with the Arias needle. The mountain stands at 3,403 m in the Écrins massif, above Saint-Christophe-en-Oisans and Valjouffrey in Isère.

The usual route to the summit is the Bec de Canard–Arias traverse, graded D in the French alpine scale, so parties cross the neighbouring Bec du Canard (3,269 m) before reaching the Arias. The mountain appears in the centre of the view mirrored in the Lac des Fétoules, with the Tête de Lauranoure to the right.

The usual route is the Bec de Canard–Arias traverse, graded D in the French alpine scale, so parties need rope, crampons and glacier and rock experience. The summit stands at 3,402–3,403 m above the hamlets of Saint-Christophe-en-Oisans and Valjouffrey in the Écrins massif. Approach and timing depend on snow and rock conditions; check them before setting out.

The lake known as the Miroir des Fétoules, or mirror of Fétoules, reflects three summits in a row: the Tête de Lauranoure at 3,323 m on the right, Le Bec du Canard at 3,269 m, and the Aiguille des Arias at 3,403 m in the centre. The alignment of the three peaks in the water is what gives the lake its name.
