We travelled from Granada to El Chorro, Caminito del Rey starting point. It was one of the most interesting route in Spain. Frightening but nowadays very safety. Must wear a helmet and walk in group. It takes about 2,5 hours. Take water and sunscreen. It is not so hard but summer temperatures are high. Windy also, which is goid if the weather is hot. If you are afraid of high places this is not for you.
