ScoutThe staff is extremely friendly, and try to accomadate with anything you could need. The campesites are fairly large with gravel pads. They offer water and electric hook-up for 30&50 amps. There is not a sewer hook up but they do offer a weekly pump out for a small fee and a dump station on the way out. The pool, ponds, playground and pavillion are all within walking distance from almost any site.

Basically the FHU loops are out in a field…no privacy from neighbors and no shade what so ever
Grass around sites desperately needed mowed, if you could get thru the large mud puddles
FHU loop D has narrow roads and require driving on grass to back in trailer and some campers in other sites had to move their vehicles
Short length of campsite required creative parking of tow vehicle
Damn Canadian Geese poop every...what a mess!
Site number on electric utility box
FHU sewer connection at the back of the campsite so bring the looooong stinky slinky FHU loop D had tiny toilet building, but no showers; showers were in non-FHU loops

LegendThis park is know for the lake that is kayak and canoe friendly since it doesn’t allow any kind of boat with a motor. It also features a beach , 2 playgrounds and several hiking trails. Just be careful if you hike with dogs since some trails intersect with a nature preserve which doesn’t allow pets.
The campground itself has 20 electric sites , 56 primitive sites and 4 camper cabins. All the electric sites are pull through and all sites have a fire pit but only the electric sites come with picnic tables.
Due to off season and COVID the camp store is closed and there is no camper host or park office staff around.
We did notice lots of downed trees on the poorly marked hiking trails. Some trails just started but no maps were around and no trails were blazed. It was hard to tell where we were headed or how long a trail was. I tried using the new Detour app and it wasn’t very accurate for this park.
We did have good Verizon cell coverage.
GuideThe pool looked to be the spot for the kids of all ages on this hot 4th of July. A well manicured campground, and while looking a bit narrow, it seemed some pull thrus for big rigs were adequate, with concrete pads and picnic tables. But all the driveways and pull thrus were gravel. Lots of seasonal trailers, and some large ones! No junk, and golf carts are restricted to electric.
ScoutThe pull through area is very cramped; more like a parking lot; the campground is quiet; family friendly; no golf carts all over;
ScoutThe campsites are shaded and pretty level. I am using a pull through and it is long enough for my RV and 24’ trailer. There is a very nice cement slab with a nice fire pit and picnic table.
GuideThis was our last camping trip of the year and it was cold. The campground was nearly empty so that was nice but the surrounding area was very crowded. There was nearly no area on the lake that didn’t have houses. The campground was clean and well maintained. There are sites that have access to get out on the water via a small canal. Some sites had good shade, and others had no shade. Overall it was a nice place, but the lake seemed very busy, even in cold weather.
GuideThis is definitely a campground for families and for those who want lots of company in there experience. There are no wooded areas in the campground so all spaces are open to all the other camper. Some shaded areas but mostly open land. Lots of activities for kids and families and even movies and music on the weekend.full power both 30 and 50 amp at almost all site and strong wifi where I was.lots of things going on up until about 10 pm. Then it quiets down. Nice place for families who want outdoor activities.
ScoutStayed 2 nights here. Had a back-in, water/electric spot that was roomy as we were on an end. Wood deck, picnic table, and fire ring included. Very well kept grounds, friendly staff, and all-around good atmosphere.

Bathroom facilities vary significantly: Campground bathroom quality ranges widely across properties.
