Know Before You Go
The cave is relatively easy to access if you know the road. Drive past Michilla, and then on the left there will be a very hard to spot road at -22.68939, -70.27071 (just before a large rock formation and where the road curves to the left). Go onto this road and continue west until you pass a few white pits filled with shells. Go around them and keep going until you see a crossroad and head to the right, then after about 650 feet you'll see a singular rock pointing out from the ground. The cave is on the north side of it.
