Radina watching over our camp at the base of Machu Picchu. It is at a place called Butterfly House. This is a project to raise different species of local butterflies in a large space enclosed by netting. Camping area (15 Peruvian soles). The Butterfly House is located along the river on your left just before the bridge as you walk along the road to Machu Picchu from Aguas Calientes.
