Great Spot for Families
I have been going here with my family for the past ~15 years and it's great. Not rustic by any means, but a great spot for kids and multiple families to have a good time. Right on Grousehaven lake with a small beach and playground and a large open grassy area for kids and dogs to to run. Biking/hiking trails run right behind some campsites so you don't have to get farther into the woods.
Great for kayaking/canoeing down the river too. You can rent from the little place across the street or bring your own - just make sure to have an extra car down at the end to get back.
Would recommend this place to anyone.
