A cluster of several boulders clustered together in the hills behind the Pond Cave.
Head to Pond Cave and then follow the trail that continues around the eastern edge of the pond. Easiest to get on this trail by either exiting pond cave on the side of Who Needs Hueco or just walking around the back of the boulder (passing the Fish and Chips Wall) and getting onto the trail behind/above pond cave. The boulders are clustered just along the trail as it winds away from Pond Cave and up a small hill.
