Fair of el Rovelló Activity · Coll de Nargó, Alt Urgell, Lleida Image of Coll de Nargó, not of the place itself. Autumn fair devoted to the rovelló, the most sought-after mushroom in the pine woods of the Lleida Pre-Pyrenees. It brings together sales of the product, a mycological display and seasonal menus in the town's restaurants, at the height of the gathering season.
