    Grand Lake St. Marys State Park accommodates pets throughout its campground with spacious sites suitable for tent camping, RVs, and cabin stays. The park maintains full hookup options and clean facilities where dogs can remain comfortable during summer visits. Camping areas feature a mix of shaded and open sites, with some pull-through spaces described as parking lot-like while others provide grassy areas with mature trees. The sites near the playground allow families to watch children while keeping pets at camp. Most sites have fire rings, picnic tables, and level pads that can accommodate larger rigs. 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. The campground features a clean saltwater swimming pool and stocked fishing pond where pets must remain leashed away from the water. Campers report the playground facilities are well-maintained and suitable for families with pets. The camp store offers basic supplies for both campers and their animals. 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.

      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.

    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 saltwater pool, a park and a clean pond with a swimming beach. Catch and release fishing allowed."

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."

    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."
