This beautifaul arch is situated in the middle of nature so you have to walk a few hours in order to see this impressive arch. The first option is: you can park your car at the Chapel of Our Señora de las Nieves in Dílar. There you take the path that goes along the "Barranco de la Ermita" in order to reach the trailhead marked by the PR A78 which you need to take. This path leads to the hill of Poco Leña. Then you need to go down to the Rambla and up to take the path that leads to the old Hermitage and Puerto de la Mala Mujer. At the port you need to take the direction of the la Silleta and walk on a sunny path that leads to Piedra Ventana.
A second option is: take the road N323 from Durcal to Padul. Turn right in front of a Seat garage (this street is named Colada de Blas de Haro) and is going up into the mountain to the old hermitage Vieja de Dilar. Follow this street to the end. When the street is turning into a dirtroad, you keep left and after a few meters you take the dirtroad to the left. This road you need to follow a few kms. It is a mountain service road and in good condition. After passing Barranco de Peña Horada you have to park you car after about 750 meters (last picture of the slide show). In the curve of the dirtroad is starting a hiking trail and will take you up another 500 meters to the arch. At all the crossings you keep left. This hike will take about 2,5 hours in total.
