The rock is granite, very dusty which makes it very hard to smear. It is a sunny place most all of the year so bring the sun screen. It is a popular place on the weekends but pretty quiet during the week. There are bolted routes.5.6-5.11 also some trad there too. There is a lot of loose rock around. Be careful.
You head East from Lima you can either grab a cab 45min and fairly expensive (round trip s/140) or a bus (1.5 hours each way s/2.50 each way per person)The climbing area is about 15 minutes outside of Ricardo Palma. just past a place called Sol de campo. The crag is a few minute walk away from the highway crossing a rickity swinging bridge.Then the trail goes to the right and wanders through some farm areas.
