Very nice, small family campground. Most of the sites are less than 100 yards from the lake. Lots of trees and brush between the sites, which are roomy. The drinking water is good, no bad taste. Minimal mosquitos. Quiet. Play equipment is in good condition. Beach and lake are clean, water is warm. Very cute goats and chickens. There are fireflies in the grassy areas. A downside for us is that dogs have no area anywhere within sight of the beach, so I couldn't sit with the dog and watch the kids. In our 48 hours there, the bathhouse was not cleaned or restocked.

We had a great stay at this campground. The kids had so much fun in the clear water, also the playground and bouncing pillow was a big hit! The staff is very friendly and the campground is well organized. They are offering large sites, we were in spot 73 overlooking the lake and offers a lot of privacy. Very easy online booking system as well. Highly recommended campground. Thank you guys for the great stay ♥️

Great experience! Small, quiet campground, clean amenities, activities for fun, owners are AMAZINGLY friendly and helpful. They let us rebook due to medical issues, and then even offered to help me park my camper as it was my first time! (long story.) Sites are nice and clean, grounds are up to date, well stocked store, swimming area and beach are wonderful. A must stop for campers! As for other reviews-I have small kids, and had no issues with noise, partying, or golf carts, and this was Father's Day wknd. I was impressed how the owners (and the pink golf cart!) enforced the rules actually. All people must stop at the office upon entering, no matter what, so you don't have a bunch of unregistered people roaming around like some places. I even watched her follow and stop a vehicle that didn't check in at the office! Impressive! The seasonal campers are friendly and it has a neighborhood atmosphere. Dont let a bad review stop you from coming!

Stopped here for a night on our way from the U.P. back to Indiana and wish we could have stayed for the weekend! Looks like it would be a really fun place to spend a few nights. Park was well maintained, owners were great, views were beautiful as we watched a storm roll to the north, and then were treated to some northern lights in the evening. Would definitely come back!

Fantastic place! The lake is large (my photo only shows a small part of it) and didn't feel full or overcrowded. Really nice playground as well. The owners are extremely active and social, and seemed to take great pride in providing the best possible experience. They gave us some great local fishing recommendations. Sites are well wooded with space between, bathrooms are nice. Showers cost $1 but give you enough time to run more than one of your kids through. We had such a great time we're coming back again next week- this is our new favorite place!
