An Area You May Want to Avoid -- The zone by the teleférico in the Casa de Campo has a very good self-service restaurant with a terrace section enjoying fine views of the park -- an excellent place to enjoy a relaxing lunch before walking down a wood-fringed park to Lago. But some 500m (1,640 ft.) to the west, it's a different story. There, the road that runs just inside the park is a pickup zone for prostitutes, with cars stopping and negotiating deals. It's also a drug zone, so you may want to avoid that particular section of the park entirely.
