There is a large car park at the beginning of the route that can be reached by car, motorhome or van. Wear suitable footwear as the terrain is stony. It can be done at any time of the year.
The top of the Sierra Prieta at 1518 meters above sea level offers wonderful panoramic views. It can be reached from Casarabonela or Alzoina by various paths, although I recommend you follow the signposts.
The climb and crisp, but worth it. The view from up here over the Sierra Blanca and the Costa del Sol is fantastic. For people afraid of heights, the last part might be a bit problematic.
