If you’re looking for a nice CG near St Louis this might be the spot. It’s close to major highways but has very little noticeable noise. There’s a really nice walking trail around the lake. Watch out for the bugs. They are really crazy after dark.

We spent four nights here at 370 Lakeside Park in St Charles MO and loved it. Sites are nicely separated; 45 are paved, 30 are gravel but all appear to be fairly level. You have plenty of room to set up a fence for the pups, or even a picnic tent so you have more shade than just your awning. Clean, quiet campground with a big lake and lots of indoor and outdoor activities for all members of the family, plus two dog parks. Historic St Charles is less than 15 minutes away! Make sure you stop by Grandma's Cookies... Best.Ever.

The people were kind, the parking was perfect for our travel trailer, and the amenities were perfect for what our family needed. Our son loved playing on the playground and running around in the grass and we were able to have time to work on our trailer since their checkout time is later.

This place is a quick getaway camp for us. But, love this park for walking, fishing and picnicking when we don't stay overnight. As a campground the only negative is a lack of shade. But, trees have to grow right? The staff are always awesome to deal with. The place is clean and very quiet. Easy access to some great places.
