Approached the summit from the easier route via the TV station. Very clear path. I would recommend some familiarity with the area or looking at a map before descending / ascending through the steep route.
Climbed together with Javi,a friend of mine, taking the long way up: following the 'Cuerda de los Porrones' (starting in 'El Boalo' area). Long and demanding hike, but very beautiful.
From the summit we went to 'Bola del Mundo' (we didn't have enough!!) and we descended by the upper Manzanares river direction 'Charca Verde', in La Pedriza. Finally, we had to climb back to the Cuerda de los Porrones to find the starting point. A whole day walking: 26 km and more than 1.600 m up.
