Coll de Nargó is well-known for having one of the most important dinosaur egg sites in the world, El Mirador del Cretaci. There are footprints and remainders of vegetal and animal fossils, eggs and dinosaur nests.
In addition to El Mirador, there is also a museum, Dinosfera. The visitor will be able to see fossils from the last generations of dinosaurs that inhabited the Earth. It is a fun and educational experience that shows how the world was by the end of the Cretaceous period and it will also help visitors discover what caused the great ecologic crisis that ended with the age of dinosaurs.
Until the early twentieth century, Coll Nargó was the largest town of Raftsmen in Catalonia alongside Pont de Claverol, in Noguera Pallaresa. Timber rafting was an extremely dangerous profession in which logs were tied together into rafts and drifted or pulled across a water body or down a flatter river. Visitors can find all the information at the Museu dels Raiers. The museum is located at Roser's old Church, in the town's old neighborhood. Every summer Associació de Raiers de la Ribera del Segre organizes a traditional party to reassemble this old profession by launching two rafts, from els Colps de Fķgols to El Pont D'Espia.
Romanesque Architecture had a big influence in Alt Urgell and Coll de Nargó is one of the towns that better maintains its rich Romanesque heritage. The most representative monument is Sant Climent's Chruch, declared of historical and artistic interest.
A recommendation for exercising and sightseeing the area at the same time would be to go mountain-biking surrounding the municipality, it is 46 km long and it is called la volta a Gavarra. It is a good trail which is easy to follow, among oak and holm oak trees, Romanesque monuments and breathtaking views of the area. Starting at the Village of Nargó, going past Les Masies, following to La Serra d'Arques, El Pla de Tolustre up until La Gavarra and finally coming back passing by Valldarques.
