Grew up near here and used to backpack across Lake Winnebago to winter camp and hike in January when the park was empty and no mosquitos to chew on my butt.
Indian Burial Mounds, old kilns, trails, hills, observation deck, sledding in winter, and lots of other things to do all year round.
This Park is actually on an escarpment that winds around Lake Michigan all the way to Niagara Falls. Limestone cliffs for climbing on, scenic.
in the summer the lake gets green with algae and there is a summer stretch wherever the lake flies hatch and get thick.
Good park for families. Close to small towns for resupply. Appleton & Green Bay are within striking distance as is Lake Michigan.
Bring arctic survival gear in January...subzero temps with wind chills in the negative teens is normal. Fantastic cross country skiing/snowshoeing.
