From jct Hwy 19 & Hwy 100 (S): Go 1/2 mi N on Hwy 100, then W 1 block to Gasconade St.
Great for campers because the town caters to out of towners. They have closed down the parking area near the basketball court for the towns people during popular times, they have a sign that says if you aren't a camper and your vehicle is parked there that it could be towed. Kinda great if you have kids, they have play equipment and they have a Dino dig area to dig for little treasures. The pool during summer is great to swim at but it is only open to the public from 12-6/7pm, but does offer swim lessons and other lessons and for pool parties
Hermann City Park is absolutely a fantastic place to go camping especially if you are in a tent or primitive camping of some sort. Everything is neat and clean and even like the playground for future times when we will bring the grandkids. This was our first experience up there and we were very pleased.
Love that they keep it very clean, well cut. Traffic through is very respectful. Only warning I have to over-nighters, tent and RV is be sure to watch the weather before your trip, be PREPARED it DOES flood in times of high precipitation. I have seen emergency evacuations several times.
