Camp ground was closed where I was deer hunting near by. So I stayed over night here. Been here a few times but never during the off season. No one was around me and only like 5 campers on far side. Which made for a fun night. All alone Definitely will be back

The Visitor Center has a small but professional exhibit for free. The aquarium is very big. Here you can see some native fish species. This part of MO is HQ for the many river systems which I learned from all the displays.

What a HORRIBLE experience! I wish I could give zero stars. I called a few days ago to reserved a campsite for a whole week. I let the nice lady on the phone know I have a 35 foot 5th wheel camper. I was assured I'd have no problem camping in campsite #68 because the pad was more than 55 feet long. When I arrived I found two trees and a post right at the entrance to the campsite.

I let the nice lady on the phone know I have a 35 foot 5th wheel camper. I was assured I'd have no problem camping in campsite #68 because the pad was more than 55 feet long. When I arrived I found two trees and a post right at the entrance to the campsite. Directly across from the campsite, right where I needed to drive to back into my assigned spot, was another post. I tried removing the badly placed posts, but they wouldn't budge. I tried also to drive over the grass to maneuver into the campsite, but the ground was too soft. There was no way to get my camper into that campsite, so I called the customer support phone number that I received with the reservation confirmation email. After being repeatedly put on hold for 15 minutes, I was told there was nothing they could do and that I'd have to call another number to speak with someone local. Someone local is who I should have spoken to from the start, because the people answering the reservation line obviously have no information about what can fit at each campsite. My frustration level was already maxed out, so I just requested a cancellation. Even though I had to cancel through no fault of my own, I was still charged a cancellation fee. I'll never stay at another Missouri State Park again.

If you are looking for very nice old wood furniture, this is definitely the place to look. Prices are reasonable for the quality of what you are getting. Things are clean and not even dusty. Laid out well so you can get around to look at things. Only negative was the owner was not very friendly.
