The park enforces standard pet policies requiring leashes and proper waste disposal.

    River Trail Campground II provides 260 pet-friendly sites with both electric and water hookups, operating seasonally from April 15 to October 15.

Sites vary in size and privacy, with some visitors noting the close proximity to neighbors. Both drive-in and walk-in access is available, though most pet owners prefer the drive-in sites for convenience. The grounds include trash collection points, shower facilities, and restrooms that stay relatively clean throughout the camping season.

      St. Mary's Section - Buckeye Trail (Points 6-7)

      On the trail Adirondack shelter

      You're learning to backpack the Buckeye Trail, and you want to take the first steps towards that without worrying about the physical load you're going to have to carry. You can drop the tent on this portion! This Adirondack shelter, located between Points 6 and 7 on the St. Mary's Section of the Buckeye Trail, is perfect for you. Built as an Eagle Scout project by Parker and Keaton Cole of Troop 95 (in Sidney), it is large enough for six or to sleep comfortably off the ground. You cannot miss it as you go along the trail. There is a fireplace (stone, make sure you check that the chimney is not blocked) large enough to cook your hotdogs and keep you happy as you sit in the shelter.  There is deadfall from the trees around you that will serve as kindling and fuel for the fire.  If you start in Lockington or Fort Loramie, this shelter is approximately 10 miles in and the right place to break a two-day backpacking trip.

      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.

      Grand Lake St. Marys State Park Campground

      Off Season and No Water

      We love camping in the off season but with that comes closures. Some sections of the campgrounds might not be open, no camp hosts and limited bathrooms and showers houses. This is to be expected, but when I called the morning of our trip to make sure potable water was available and I was told yes it was only to drive 2 hours and realized they were wrong. No water 🙁. This would not have been a peas we have dry camped before but all the bathrooms were closed as well.

      After called the park ranger he did let us get some water at the maintenance building so we were at least able to finish the weekend. Lesson learned always pull with at least some water.

      Now back to the campground itself was nice and clean. Site are a little close together. The biggest down side is you are there to enjoy the lake but the lake had algae warnings everywhere not to go near the water.

      They do have a dog park, pool and splash pad when in season and a marina. Also they have WiFi and good cell coverage.

      Lake Loramie State Park Campground

      Perfect retreat for the family or solo adventure

      Relax on the waters edge in shear tranquility. Perfect beach for swimming, excellent trails for hiking, and awesome lake to boat. Multiple launch ramps provide ease and convenience. Rent a canoe or kayak and head out for some time alone or with your favorite person. The cabins are heated but pets are not allowed. Campground is huge as are the sites. Some are premium, there’s a few ADA and some lakeside making for a great view to enjoy your morning coffee.

      Kiser Lake State Park Campground

      Beautiful lake, no running water, feral cats

      This park has a beautiful lake and nice (although short) hiking trails. The problem is that there is no running water- no showers and smelly pit toilets. There is one spigot for drinking water.

      Beware that the campsites are mostly in one big grassy field with no shade. I'd pick a site along the perimeter or along the lake.

      This park is overrun with feral cats (or it was when I was there). Some people might think that is cute. I consider feral cats to be wild animals that carry disease. What's really bad about them is that they've been fed so they are comfortable around people. We spent the whole weekend trying to fend them off- every time our backs were turned, they jumped up on our picnic table. They ate our food, which we had to throw away. When we sat by the fire, they rubbed up against our legs, which is disgusting, considering they carry Bartonella, which is transmitted through their fleas and ticks (Bartonella is a co-infection of Lyme, or you can get it on its own. I know- I've had it since middle school. Feral cats probably carry Lyme too, as they are mammals). I can't express how stressful it was, trying to keep these wild cats away from us the entire weekend. I don't know why the park can't get them under control.

      Sure, cat people will be offended by my statement, but would you want raccoons or skunks up on your table, eating out of your pots and pans? Would you want raccoons rubbing up against you while you are trying to relax? These cats are also wild animals, yet way too tame for comfort. Ugh,I shudder remembering it.

      Kiser Lake State Park Campground

      Quiet Park

      This park is know for the lake that is kayak and canoe friendly since it doesn’t allow any kind of boat with a motor. It also features a beach , 2 playgrounds and several hiking trails. Just be careful if you hike with dogs since some trails intersect with a nature preserve which doesn’t allow pets.

      The campground itself has 20 electric sites , 56 primitive sites and 4 camper cabins. All the electric sites are pull through and all sites have a fire pit but only the electric sites come with picnic tables.

      Due to off season and COVID the camp store is closed and there is no camper host or park office staff around.

      We did notice lots of downed trees on the poorly marked hiking trails. Some trails just started but no maps were around and no trails were blazed. It was hard to tell where we were headed or how long a trail was. I tried using the new Detour app and it wasn’t very accurate for this park.

      We did have good Verizon cell coverage.

      Huggy Bear Campground

      Overall a great experience

      Clean! Tons to do especially for kids, pet friendly, definitely get rowdy on the weekends- book ahead to snag the best sites. We stayed 5 days and it was awesome. Mini golf, fishing, 3 pools, inflatable in the water, they have a whole schedule for the weekends here. It’s great!

      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.

      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.


    Guide to St. Marys

    Camping near St. Marys, Ohio offers a mix of waterfront sites and recreational amenities in western Ohio's flat terrain. The region experiences humid summers with temperatures regularly exceeding 80°F, making water activities particularly popular. Most campgrounds in the area sit at elevations between 850-950 feet above sea level, creating level camping conditions ideal for both tent and RV setups.

    What to do

    Water activities at Lake Loramie: Lake Loramie State Park offers multiple opportunities for boating and fishing. One camper notes, "Love being so close to the lake we can fish all the time. The beach is a bit of a walk from the campground but not too far. They offer canoe rentals, and bike rentals."

    Visit local museums: The Wapakoneta KOA provides convenient access to the Armstrong Air & Space Museum. A visitor shares, "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."

    Miniature golf and recreation: Several campgrounds offer on-site activities beyond swimming and hiking. At Arrowhead Lakes Resort, visitors can enjoy "their new 18 hole mini golf course, small arcade (4 games and pinball was broken), loaner bikes, and water toys (we liked the paddle bikes)."

    What campers like

    Clean facilities: Ottawa Metro Park Campground receives praise for its maintenance standards. A camper reports, "This is a beautiful, peaceful campground that's not a parking lot like many city campgrounds. It's clean as clean can be, including the bathrooms."

    Saltwater swimming options: River Trail Campground II offers alternatives to lake swimming. According to one visitor: "The papers were friendly and helpful. Friendly patrons throughout the park. Clean saltwater pool, a park and a clean pond with a swimming beach. Catch and release fishing allowed."

    Well-designed sites: At Ottawa Metro Park, campers appreciate the thoughtful layout: "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 area can have water quality issues during summer months. At Indian Lake State Park, a camper mentioned: "There are a ton of sites. Some had great shade and others didn't have any at all... They have a dog park, place to dock your boat and a small beach."

    Seasonal operations: Many campgrounds have limited operating seasons. River Trail Campground II runs from April 15 through October 15, while others may close even earlier depending on weather conditions.

    Site variations: Campground layouts vary significantly across the region. At Cottonwood Lakes, one camper shared: "This is a local's campground. Many permanent camps. We camped in the primitive area and were the only ones there."

    Tips for camping with families

    Playground proximity: Consider site location relative to play areas. At Grand Lake St. Marys State Park, one parent appreciated: "The camping spot was great. It was very close to the pool and playground. The sites were pull through which was nice for have young kids. Could sit at our spot and watch our kids at the playground."

    Swimming options: Most campgrounds offer alternatives when lake swimming isn't possible. Indian Lake State Park features "a camper beach area, swimming pool and boat launch within the campground."

    Activity planning: Look for campgrounds with organized events. At Lake Loramie State Park, campers enjoy the "Fun Field Day activities! Plenty of fishing and relaxing! We love the little ice cream shop/bait shop across the street."

    Tips from RVers

    Site selection: At Lake Loramie State Park Campground, RVers should note that "The sites vary in size and privacy, with some visitors noting the close proximity to neighbors." Another reviewer observed, "The campground is like a giant RV lot. The sites are tiny."

    Hookup availability: Ottawa Metro Park Campground provides "Water and electric 30 Amp and some 50 amps as well." This makes it suitable for pet friendly camping near St. Marys, Ohio for those with larger rigs needing higher amperage.

    Level sites: Many campgrounds in the St. Marys region offer relatively level sites, though some require adjustments. At Indian Lake, one camper mentioned: "Our pad was not level front to back so we had to adjust a little bit."
