Pic du Grand Doménon, Mountain summit in Belledonne range, Isère, France

Pic du Grand Doménon is a summit of the Belledonne range in the Isère department, reaching 2,802 metres. Its upper part is bare grey rock: a steep, roughly triangular main peak with a jagged crest, joined on the right by a slightly lower craggy shoulder that leads to a broad rounded ridge. Darker grey-green slopes fall away below the stone.

The sources record no medieval use or 19th-century ascent of Pic du Grand Doménon; the summit stands at 2,802 m in the Belledonne range of the Dauphiné Alps, in the Isère department. The documented route to the top starts at the Lacs du Doménon and passes the Col du Bâton before gaining the summit.

The usual route to the summit starts at the Lacs du Doménon and crosses the Col du Bâton before the final climb. The two lakes below the peak are a destination for day hikers from the Isère valley, and the col is the pass walkers cross to reach the summit ridge.

Marked trails from Doménon lake lead to the summit and offer the best trekking conditions during summer months. Good footwear and proper fitness are important since the climb takes several hours.

The summit is reached from the Lacs du Doménon by way of the Col du Bâton, a route that crosses the pass before climbing the final slopes. The jagged grey crest seen from below is the highest point of the Grand Doménon massif, at 2,802 m in the Isère department.
