You need to find the tiny puddle in the middle of the tree area. it's about 4x4, maybe a little bigger. It's very small, not a lake by any means.it is tricky to find but keep making your way to the middle. Use the random rocks placed around the area to help. They are arranged in a circle, so just use that to help you. Once you find this puddle you will trigger an event that will let you climb the stairs.
