The waterfall is tall and very beautiful; it's best visited after a period of heavy rain or when there's snow in the area. It's located within the municipality of Canencia and is easily accessible via forest tracks from the Canencia Pass, coming from the south (Miraflores de la Sierra and Madrid) or from the north (Canencia in the Lozoya Valley). A longer approach is also possible from the M-611 via the Collado del Hontanar pass (1,731 m). If you approach the waterfall from its eastern side, be very careful of slipping, as it could be fatal. The ground is often wet and even icy in autumn and winter.

The traverse between Peñalara and Claveles, or vice versa, requires skill and good footwear. Wet rock, and especially snow or ice, can make it much more difficult. Roped up is advisable in the worst conditions.
