About 200 meters before a sawmill, the entrance is not very visible. You go up the hill by a little marked trail until you reach the place where the stone is next to a reservoir of water.
Few know about the place and the locals are not very aware about the stones. There is no signage and there is little information on how to get there.
To get to Cotundo you can take a bus from Tena ($ 0.75, 30 min) or a taxi for $ 15.
