Puig d'Ombriaga, Mountain summit in Eastern Pyrenees, France

Puig d'Ombriaga, called Pic de l'Esquena d'Ase in Catalonia north of the border, is a 2,626 m mountain on the main Pyrenean ridge between Setcases and Fontpedrosa. Its slopes are bare rock and scree in grey, beige and green-brown, cut by gullies, with smoother, lighter ground and rusty pinkish patches near the crest.

The summit sits on the main Pyrenean axis, on the limit between the municipal term of Setcases (Ripollès) and the communal term of Fontpedrosa (Conflent). The Catalan name Pic de l'Esquena d'Ase is used in northern Catalonia, while the southern Catalan side calls it Puig d'Ombriaga. It lies just southeast of the Fontpedrosa boundary and northwest of Setcases, southwest of Puig de Morens and northeast of Coll del Gegant.

The mountain lies on the main Pyrenean axis, where the municipal term of Setcases (Ripollès) meets the communal term of Fontpedrosa (Conflent). Its two names reflect that split: Pic de l'Esquena d'Ase in northern Catalonia, Puig d'Ombriaga in southern Catalonia. The summit sits near the south-eastern end of Fontpedrosa's territory, south-west of the Puig de Morens and north-east of the Coll del Gegant.

The summit lies on the French-Spanish border between the municipal terms of Setcases (Ripollès) and Fontpedrosa (Conflent), just southwest of Puig de Morens and northeast of Coll del Gegant. Approach from the Fontpedrosa side or from Setcases; the final slopes are bare rock and loose scree, so allow for slow going near the top.

The summit marks the border between Setcases in Ripollès and Fontpedrosa in Conflent, so the ridge line divides Catalonia's two historic comarques. The Catalan name Esquena d'Ase means "donkey's back", while the southern Catalan side calls it Puig d'Ombriaga.
