There are two or three other places nearby where you can park for the night and enjoy the views. When we were there the village was deserted, all hospedajes and restaurants closed and no restrooms in sight. Cascadas are okay, but not worth a huge detour. If coming from Lima note that approach from San Mateo/Chicla is a 5-6h (100 miles) long drive on dirt tracks.
