Nez de Boeuf, Mountain summit in Réunion, France.

Nez de Boeuf is a summit in the Piton des Neiges massif on Réunion, rising to 2,089 metres, about 40 km south of Saint-Denis and 13.7 km from Le Tampon. Its broad, roughly conical form ends in a darker peak, with volcanic rock and dark green scrub covering the slopes. A thin pole stands on the right slope, and another vertical pole is visible near the lower middle base.

Nez de Boeuf is one of two Réunion summits bearing the name, this one in the Piton des Neiges massif, 2,089 m high and about 40 km south of Saint-Denis. The sources record no exploration history for it; the summit rises 62 m above its immediate terrain, with a 1.1 km-wide base, and the nearest town, Le Tampon, lies 13.7 km to the southwest.

The summit's name, "Nez de Bœuf" (ox's nose), comes from its profile as seen from the approach road. Two separate summits on the island share this name: this one at 2,089 m near Le Tampon, and another in the Piton de la Fournaise massif. The name is written with the ligature œ in French.

A path of about 700 meters leads to an observation deck equipped with picnic tables and shelters. The route is accessible for people with reduced mobility, making the site welcoming to all visitors.

The site is known for one of the longest fully accessible paths on the island, with special orientation aids for visually impaired visitors. This level of accessibility makes it exceptional among mountain destinations in the region.
