We recently spend the weekend at Punderson State Park Campground to visit family.  There is a ton of stuff to do at this park and it is spread out so you do not feel on top of each other.  We stayed at Site 11, this site is on the road with full hook-ups only.  The rest of the part is water and electric.  We enjoyed hiking, biking, kayaking and sharing stories.  There is a beautiful lodge across from the campground that has cabins to rent.  Although we didn't play, there is a 27 hole disc golf course, a regular golf course, archery range and several hiking trails.  This place will be on our list to return.  The only downside was the lake had alot of algae, but this is expected in the heat of summer.
