Sand Pond was added to the forest preserve in 1999 as part of the Croghan Tract. Access is via logging roads and a .2 mile carry from the parking area. Its marshy shores support an abundance of waterfowl and wildlife. Narrow corridors of stream, best paddled at high water levels, connect Long Pond, Rock Pond and Mud Pond. On the east end of Mud Pond is a newly installed handicapped accessible dock, outhouse and parking area. Below Mud Pond there are two waterfalls. A short carry trail leads to the base of the first waterfall, and then there's a .7-mile paddle to the takeout at a footbridge above the second waterfall. A steep trail leads to its base.
