    Campers can find multiple camping areas near St. Marys, Ohio with options ranging from established state parks to private campgrounds. Grand Lake St. Marys State Park offers tent, RV, cabin, and glamping accommodations with full hookup sites and amenities including showers, drinking water, and picnic tables. Lake Loramie State Park Campground, located about 15 miles southeast of St. Marys, provides similar accommodation types with boat-in access and hiking trails.

    Camping availability in the region typically runs from April through October, with some campgrounds like Grand Lake St. Marys and Lake Loramie State Parks remaining open year-round. Most established campgrounds require reservations, especially during summer weekends and holidays. Water access is a significant feature of camping in this area, with many sites offering proximity to Grand Lake St. Marys or Lake Loramie for boating, fishing, and swimming. However, water quality concerns occasionally affect recreational activities, particularly at Grand Lake St. Marys. As one camper noted, "The lake is so big, it was like being on the ocean! Could not swim in the water due to contamination which they have spent millions to repair and is slowly on the up and up."

    Several visitors mentioned the family-friendly nature of campgrounds in the area, with amenities like playgrounds, swimming pools, and organized activities. Campsite privacy varies significantly between locations, with some offering wooded sites while others feature more open layouts. A camper reviewing Lake Loramie State Park wrote, "Relax on the waters edge in shear tranquility. Perfect beach for swimming, excellent trails for hiking, and awesome lake to boat." Campground density tends to be higher during summer months, particularly at waterfront sites. For those seeking more seclusion, primitive camping options exist along sections of the Buckeye Trail, including an Adirondack shelter between Points 6 and 7 on the St. Mary's Section that accommodates up to six people and features a stone fireplace.

      Indian Lake Adventures

      This Is A Review

      Campground is clean and quiet.

      Camp sites are grassy surrounding a flat gravel park site. Sites are wooded with good amounts of shade. There are very few nightly sites - most of the sites here are seasonal only. We were here in the second week of June and hardly saw a soul outside their camper or walking around the campground.

      Bathrooms are clean and spacious. Showers don't have benches or shelves. The water smells strongly of sulfur.

      Camp Brewing is the brewery at the entrance of the campground. Highly recommend a visit! Great variety of beers and excellent vibes. Dogs are allowed on the patio and they have a kitchen that makes pizza and wings.

      Overall, would stay here again. Wish there was a little more livelihood around the camp sites, but this is a great spot to enjoy the quiet.

      Fairgrounds early in the year

      Clean, quiet and very nice. One of about 10 RVS in the park, nice and peaceful. They were exercising the horses this morning, and I really enjoyed watching. The staff was excellent. I thought the experience was great.

      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.

      Wonderful facility! Pool, pool table, games for kids and adults. The grounds are beautiful and the staff is super friendly and helpful! Oh and in the laundry room they even have a sink for washing dishes! Great for tent campers ar those with small units that don't have kitchens.

      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.

      Grand Lake St. Marys State Park Campground

      Campground is fine but the lake reeks of POO

      First the good: the campground is big and spacious. Some areas were like RV parking lots- no trees, no shade, but there was a grassy area in the middle with nice big trees and shade. There is a nice pool and splash pad. Weirdly, the pool closed from 4 to 5, leaving us with nowhere to go on a 90+ degree day. 

      Now, the not-so-good: we stayed in a camper cabin and it was very shabby and dirty. It had bunkbeds, a full size fridge, and a folding table and folding chairs, which was nice (and rare in Ohio state park camper cabins). The bathrooms were average. Not new, not especially sparkling clean, but fine. Not gross, at least.

      Now, the terrible: the entire lake stinks of pig poop. All the air smells like poo. You feel like you are breathing feces when you approach the water. We were right on the water so we couldn't escape the smell. 

      This lake is notorious for having algae blooms that prohibit swimming. So I did a google search before our trip and the Ohio Department of Health reports that the bacteria level in this lake is dangerously high, and no one should swim in this lake. However, when we walked to the campground beach, there was no sign or warning or anything indicating the bacteria in the water- and people were letting their children and dogs swim in it!! 

      We opted to not kayak or paddleboard in the lake because it was clear that it was full of poop. So we had nothing to do at the park except go to the pool (it was too hot to do anything else). We ended up driving around the country roads and seeing the sights so we could escape the smelly lake and hot poo fumes. 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. 

      Overall, I will not return to this lake or this part of the state. If you can't get in the water, paddle board or kayak, the only thing left to do is ride around in a boat and hope the water doesn't get anywhere near your mouth or your skin. No thanks.


    Guide to St. Marys

    Camping spots near St. Marys, Ohio tend to be busiest from Memorial Day through Labor Day when temperatures average 75-85°F. The flat topography of western Ohio creates camping areas with minimal elevation changes, making most sites accessible for all mobility levels. Several campgrounds in this region offer non-water recreation options like mini-golf, game rooms, and organized weekend activities.

    What to do

    Fishing opportunities: At Grand Lake St. Marys State Park, the lake supports multiple fish species despite water quality concerns. One camper noted, "The campground is big and spacious. Some areas were like RV parking lots- no trees, no shade, but there was a grassy area in the middle with nice big trees and shade."

    Playgrounds and recreation: River Trail Campground offers activities beyond swimming. A visitor mentioned, "My kids had a great time, the playground is very nice, there is a nice pool and a clean pond that is stocked with bluegills."

    Visit nearby attractions: The Wapakoneta area contains points of interest related to astronaut Neil Armstrong. As one camper at Wapakoneta KOA shared, "Neil Armstrong was born in Wapakoneta and the Armstrong Air & Space Museum is also a max 5 min drive away if you want to get your inner astronaut fix."

    What campers like

    Clean bathhouses: Campers frequently mention bathroom cleanliness as a standout feature at Ottawa Metro Park Campground. One reviewer stated, "It's clean as clean can be, including the bathrooms. The bath house has men's and women's bathrooms as well as a largish entry room with water fountains."

    Swimming options: Multiple water recreation choices exist beyond just lake swimming. A visitor to Indian Lake State Park Campground commented, "There is a camper beach area, swimming pool and boat launch within the campground."

    Level sites: Many campgrounds offer well-maintained camping pads. One reviewer at Ottawa Metro Park noted, "The sites are well spaced and beautifully maintained. We picked site 30 because it had ample trees on its west side to create nice shade in the afternoon."

    What you should know

    Water quality concerns: Several lakes in the region experience periodic algae issues. A camper at Lake Loramie State Park reported, "There were signs posted everywhere to use caution with the water because they were know to have blue green algae in the water so we had to keep the dogs away from it."

    Site privacy varies: Campground layouts range from open to partially wooded. An Indian Lake visitor explained, "The down since a lot of site are in full sun and no privacy. We do like the B section and try to stay there when we can."

    Seasonal mosquitoes: Bug activity peaks in summer months. One Lake Loramie camper shared, "The bugs were really bad every time we were outside. There are several nice walking trails but the mosquitoes were so bad even in the day that we kept away."

    Tips for camping with families

    Pool access timing: Check pool schedules for closures or restrictions. A Grand Lake visitor mentioned, "There is a nice pool and splash pad. Weirdly, the pool closed from 4 to 5, leaving us with nowhere to go on a 90+ degree day."

    Weekend activities: Many campgrounds offer structured programs. At Ottawa Metro Park, "While we were there, there was a Blue Grass music event scheduled at the nearby amphitheater."

    Kid-friendly campsites: Choose spots near playgrounds for convenience. A camper at River Trail noted, "We had a great weekend of camping! The weather was perfect, the kids loved the playground and had fun at the Fun Field Day activities!"

    Tips from RVers

    Site dimensions: Check specific site measurements before booking. A visitor to Wapakoneta KOA advised, "The actual sites are very small. Not much room to fit the trailer and vehicle. Basically the site is as wide as your awning."

    Pull-through configurations: Some sites have cramped pull-through arrangements. At Grand Lake St. Marys, a camper observed, "The pull through area is very cramped; more like a parking lot; the campground is quiet; family friendly; no golf carts all over."

    Amenities vary by section: Campground sections often have different features. An Indian Lake visitor pointed out, "We do like the B section and try to stay there when we can. There are no hiking trails or at least none that I have found and the paved trail you have to drive to as well as the disc golf course."
