    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. According to The Dyrt, several private campgrounds like River Trail Campground and Wapakoneta KOA supplement the public options with additional amenities and seasonal availability.

    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.

      Lake Loramie State Park Campground

      This was our first time here. We only stayed one night as we were on our way to Indiana. We were on site 16 which was right next to the Parks building and one of the camp host and right across the street from a playground. It was a short walk to the shower house and the campground itself was very clean and well taken care of. At the back of our site it was like a big giant backyard and it led to the canal.

      Lake Loramie State Park Campground

      Great camping. It’s smaller but most sites are great. There is a lot of site that are on water or close to water. Very clean and well maintained . This is perfect for fishing, boating and kayaks.

      Blue Water Campground

      Easy Overnight Spot

      Traveling on I40 in mid-October, I planned to stop at Joe Skeen.  In the past I have stayed at Quaking Aspen (Ft. Wingate), but it is often deserted in the off season.  Unfortunately, Joe Skeen was full, but TheDyrt showed me my options and I ended up backtracking a little way to get to Bluewater State Park.  

      Beware of the drive in. The turns are well marked, but there is a cliff on the other side.  First Come First Served registration was easy in the off season.  I did not use the facilities.

    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."
