    Dayton KOA Holiday

    Very clean and shady

    The campsites are shaded and pretty level. I am using a pull through and it is long enough for my RV and 24’ trailer. There is a very nice cement slab with a nice fire pit and picnic table.

    What would you expect from Camping?

    Do you have kids? They have it covered, from playground, to lake with inflatables, train rides, Holiday fun.

    Adults? I see Cornhole every weekend, Campfires, Holiday Events, Golf Cart Parades, DJ's or Live Bands on the weekend, Friendly Seasonal Folks always up for a good time.

    Ameneties? Bath Houses, Laundry, General Store, Small Grill and Pizza Oven. (Pizza is not half bad either).

    Amish make their presence felt on a few weekends throughout the season, from fresh Bakery Goods to a Healthy Sized Sausage Egg Biscuit. (You won't be disappointed)

    Food Trucks on a few weekends throughout the season.

    Summit Lake State Park Campground

    Summit lake state park

    Its an ok park. The water is shared with your neighbor, so be sure to have a lo g hose. The showers were sketchy. I wouldn't use them personally. Wecsaw a couple of unattended fires smoldering in empty campsites. And we paid for an overnight reservation. Came in around 5pm. They charged us $7 for day use. I dont think you should have to pay for day use ANYWHERE that you've paid an overnight reservation. We are through travelers and its just plain irritating to me.

    Kil-So-Quah - J. Edward Roush Lake

    No Lake access from campground

    Forest settings, electricity for only $15/night. Lots of traffic in and out. A lot of older rigs.

    Indian Lake State Park Campground

    Lots of sites

    Our pad was not level front to back so we had to adjust a little bit. The fire ring was nice but our picnic table was beat up. I went to move it and the seat pulled right off. We stayed on a Sunday night so it wasn’t packed. There are a ton of sites. Some had great shade and others didn’t have any at all. The bathrooms were flush toilets and they did have shower houses too. The camp store is really big and it’s right next to their pool. They have a dog park, place to dock your boat and a small beach. I would imagine this would be a pretty busy during the summer.

    Resting Roost

    Okay for one night I guess

    We were kind of stuck, looking for a place to stay as we didn’t have reservations during Labor Day weekend so found this place that was listed on Hip Camp. Near Belle Center. PROS- was relatively cheap, $24,out in the middle of fields so pretty quiet, host seems pretty nice. CONS- had to back up a 100 yard driveway, lots of bugs, smells as they just fertilized the fields (not the owners fault). Okay for setting up a tent or a small rig but wouldn’t advise for trailers. Electric was an extension cord. I think water is available. Owner could have mowed the place a bit.

    Summit Lake State Park Campground

    Peaceful park and great hiking trails

    Although we only spent one night here during the week, the campground seemed very peaceful and quiet, even though there were quite a few campers. Sites 1 through 74 seem to be a lot more level and larger, but they were in a sort of an open area with very little shade. The rest of the sites were fairly unlevel, but were in shaded areas. I would think a rig more than 31 or 32 feet long would have difficulty maneuvering around the curve at the end of the second loop. We are a 30ft. Fifth wheel and it was pretty tight for us. Lots of trees. The showers were your typical camp showers not great but not horrible. There was a large lake that one could enjoy fishing on. Also some great hiking trails in the area.

Local attractions: Explore beyond campgrounds with nearby points of interest. "We ended up driving around the country roads and seeing the sights. Neil Armstrong was born in nearby Wapakoneta so there are some sights to see there, and the towns of Celina and one other are cute too," shares a Grand Lake St. Marys camper.

What campers like

Pool facilities: Swimming pools provide relief when lake conditions aren't favorable. River Trail Campground receives praise for its water facilities. "Nice saltwater pool, a park and a clean pond with a swimming beach. Catch and release fishing allowed," reports a camper.
