The Sand Dunes Trail traverses higher ground, passing through an area of large, open sand dunes---remnants of ancient, glacial beach ridges. The unique topography of this high and dry, desert-like habitat, inter-mingled with nearby, low, wet depressions supports many types of rare and unique plant species. Watch for tracks of coyote, wild turkey, and snakes. Portions of this trail are closed from May 1-July 1, due to ground nesting birds, such as the state endangered lark sparrow and the rare, antenna-waving wasp.
Parking for this trail can be found at Mallard Lake Area.
