This comprehensive road bike itinerary is made up of two excellent loops that can be covered separately, setting off from Barbastro, Naval, Aínsa o Boltaña. Each loop is one of the classic circular routes of the area: the one from Barbastro to Abizanda and Bárcabo has 105 km in length and 1600 m of vertical gain, while the loop from Aínsa to Las Bellostas and Arcusa has only 59 km in length but 990 m of vertical gain. Both together result in a very demanding route if done in just one day due to its high accumulated height difference, only achievable for cyclists in good shape. If the tour is divided in two stages it becomes an atractive and pleasant mid-mountain route with great landscapes and a rugged profile where the mountain passes of El Pino, Arcusa, Serrablo and San Caprasio stand out.
