KOA Lake Milton Berlin Lake

Highway noise from nearby roads carries across this KOA's flat, open terrain, making conversation around evening campfires challenging at times. The campground accommodates RVs up to 125 feet with full hookups and operates seasonally from May through October in Diamond, Ohio.

A small swimming lake anchors the property's recreation offerings, featuring inflatable water toys and a designated swim area. Fred R. notes it's a "good fishing lake as well," while nearby Lake Milton provides additional boating opportunities just down the road. The campground includes a playground, jumping pad, and game room that stays well-maintained throughout the season.

Sites sit close together with limited privacy between neighbors, though the level terrain makes setup straightforward for most RVs. Full hookup sites include electric, water, and sewer connections, while primitive tent sites occupy open field areas. The restroom and shower facilities receive consistent praise for cleanliness, and staff maintains daily trash pickup across the grounds.

Campers seeking more dispersed options might consider Nelson Ledges Quarry Park - Heaven on Earth, which offers a different camping atmosphere north of the area.

Numerous guests pointed out excellent family amenities and exceptionally clean facilities with helpful staff. However, visitors commonly noted high pricing, close site spacing, and highway noise as drawbacks.

Kids loved it

Overall we had a great time, kids absolutely loved swimming in the little lake and sliding/jumping off the inflatables. My only complaint is that the sites are very close together, it felt like we had no privacy at all.

Too expensive for one night

We arrived after 10pm and left by 10 am and paid over $80. Our spot was level but our sewer hookup was next to the neighbors campfire so we couldn’t hook up and had to use the dump station before we left. There were tons of fun attractions for kids so if you’re planning to spend time with your kids it looks like fun but too expensive for a nights rest on the road.

Cabin

Last August rented Cabin. It was beautiful and very clean. The owners were great and very helpful. !! Cabins are a little high in price.No WiFi,. KOA should lower the prices due to that. Activities are great keeps the kids interested. KOA should have on all camping sites Life Guard if there is water sports involved.Game room was nice and clean.Change machine needs to stay stocked.Fishing lake was great. I think with full swing in Season they should offer more activities for adults too.Camp Store should be more orangized. Bathhouse was very clean!.Trash was picked up every day and the Park very clean.! We have booked another Cabin for May 2021. They have a limited rental on Life jacket s. Bring ur own.!

My 2 boys had so much fun at the lake and the playground and the bounce pad ect ect! The owners and all the staff were extremely friendly and helpful and always around interacting with the guests. We will surely return for another visit!

Not that impressed

We decided to spend a weekend there frankly due to convenience. I did think it was a little expensive when we booked, but we booked anyway. We then decided to book a primitive tent site with no power for my father-in-law. Over $80 for two nights! To make matters worse, he got there around 12:30 in the afternoon and they charged him $15 for early check in. It was a tent site, in a field, with no power. Bags of ice we $4. The bundles of wood were priced competitively to other campgrounds, but the wood was terrible. We bought 5 bundles, the wood was wet and rotted! I will say the kids jumping area and playground was really nice. The swimming lake was pretty gross. Lots of algae and lots of mud. The couple bright spots were really friendly and helpful staff and the restroom/shower facilities were really clean. Not sure if we will go back.

Easily accessible

Nice and flat grounds. Alot of sites for its size. Very nice lake and inflatables in swim area. Good fishing lake as well. Lake milton is a jump down the road for boating. But the hiway noise was just too much for the kids to sleep, and to enjoy a night at the fire having to yell at times.
