Col de la Leisse, Mountain pass in Savoie, Auvergne-Rhône-Alpes, France

Col de la Leisse is a mountain pass at 2,761 m in the Savoie department, on the GR 55 long-distance trail. It links Termignon in the Maurienne with Tignes in the Tarentaise and lies within Vanoise National Park. The broad saddle is bare grey and brown rock and loose scree, with snowfields and short grass on the lower flanks; a signpost near the pass points to Tignes le lac, the Refuge de la Leisse and Bellecombe.

The pass lies near the source of the Leisse stream, whose name comes from a variant of Axia with the article agglutinated, meaning "water, to flow, to wet". It is one of the crossing points between the Maurienne valley and the Tarentaise, specifically Tignes, and today only a mountain path, the GR 55 long-distance trail, goes over it.

The name Leisse derives from a variant of Axia with the article agglutinated, meaning water or to wet. The col lies on the GR 55 long-distance trail, and the Refuge de la Leisse stands near the pass. The weathered wooden signpost at the pass lists Tignes le lac 2h, Refuge de la Leisse 1h30, Refuge d'Entre Deux Eaux 3h15 and Bellecombe 4h5.

The hiking season is best from June to September when snow has melted and trails are accessible. Wear sturdy boots, bring weather-appropriate layers, and carry water, as the exposed terrain offers little shelter from wind or sudden weather changes.

The pass lies on the GR 55 long-distance trail, and the Refuge de la Leisse stands close to the col. From the surrounding slopes the cable car of the Grande Motte is visible, and one of Tignes' ski lifts plus a few pistes run up the upper Leisse valley near the pass, below the Grande Motte glacier.
