Col du Soulor (elevation 1,474 m (4,836 ft)) is a mountain pass in the Pyrenees in France, linking Argelès-Gazost with Arthez-d'Asson.

A road leaves the pass to the west to reach the higher Col d'Aubisque.

Starting from Argelès-Gazost (east), the Soulor is 19.5 km (12.1 mi).

[4] The Col du Soulor was first used in the 1910 Tour de France[5] and was most recently featured in the 17th stage of the 2010 Tour de France, as a category 1 climb.

When this route is used, for example in stage 16 of the 2012 Tour de France, it is often not a categorized climb,[7] since the amount of re-ascent from the west is relatively small.
