Mont Colombis, Mountain peak in Hautes-Alpes, France

Mont Colombis is an isolated mountain in the Hautes-Alpes, rising to 1,733 metres between the Chorges–La Bâtie-Neuve depression and the Durance gorge. Its slopes are covered with dense forest, with beech woods on the north side and juniper and holm oak on the south. Near the summit, two thin towers stand in a clearing on the upper left slope.

The summit lies on the boundary between the communes of Théus and Espinasses, while its slopes are divided among nine communes including Remollon, Valserres and Chorges. In 2013 the summit gained a weather radar installed for the RHyTMME project, inaugurated on 19 September 2013, and a major radio relay station also stands there.

The summit is a launch point for paragliders and the finish of a waymarked cycle route set up by the Hautes-Alpes departmental tourism committee. A cross erected by the inhabitants of Théus stands at the top, and the summit also carries a large radio relay station.

The summit can be reached by car via roads from Théus or on foot using hiking trails from Chorges and Avançon. Visitors should prepare for Alpine weather conditions that change quickly and bring appropriate gear for mountain terrain.

At the summit sits the RHYTMME radar station operated by Météo France, which monitors storms and flood risks across the Southern Alps in real-time. This specialized equipment plays a key role in early warning systems that protect people throughout the region.
