the nicest and most well maintained corps park we’ve ever stayed and we’ve stayed at several. the grounds were closely mowed, sites were level, spotless and roomy, bathrooms were spotless! whoever maintains the park does an outstanding job. one end of the park to the other is about 3 mi and completely flat w a nice asphalt road where we rode our bikes along the beautiful river every day. our site (35) was about 150’ from the river where we fished. watched the barges and boats go by. extremely relaxing and tranquil. town was about 20 minutes away if u need supplies.

shower and restroom facilities need upgrading. The basketball court/tennis/court needs repair The campsites are clean and very well maintained and have scheduled trash pickup. Overall the campground is a great place to stay and the staff is very helpful

The only recommendation I can think of to improve this excellent campground is to identify the campgrounds site numbers more clearly. They are very hard to see.

We had a reservation (Site 24) but ran into our first (and hopefully last) WHERE DID THAT COME FROM???? tornado/ hail as we arrived from the south. Called the campground to check on weather. CONNIE is THE most amazing camp host. She not only waited to be certain we arrived safely (….pretty steep incline but our 36’ gas powered Tiffin WITH a TOAD, made it just fine) and escorted us to our riverside site, is our chocolate lab’s new BFF, and was SUCH a friendly face to arrive and see at checkin. I cannot imagine how frazzled we looked after that storm. It was frightening and I don’t scare easily.
Sadly, we only spent one night enroute to Michigan but we would ABSOLUTELY return. The river on our loop was high and saw zero alligators! 😅
