Snowboarding the three valleys means; El Colorado, la Parva and vallee Nevado.
Each has their own character, El Colorado has good all round terrain, La Parva family orientated and Vallee Nevado short steep slope. The best terrain was down to the Vallee Nevado access road where the Freeride world tour recently used the Santa Theresa face. We parked the El Colorado camper van in the car park for the entire time we were there, cold but effective.
