We came to Heavener Runestone Park with three families and nine young children and had the BEST time! Totally worth the drive from Tulsa. The park is beautiful and secluded, very clean and well kept. It has some really fun little themed touches in keeping with the Viking Runestone. The history around the Runestone is so interesting, the kids loved hearing about the Vikings. The hiking was beautiful and just challenging enough to be fun while accessible for little kids. Bathrooms were clean and easily accessed from our tent sites. The views were spectacular. Out of the three cliff tent sites I would say only 1 was safe for kids, 2 and 3 were too close to the cliff (beautiful views though). The playground was really fun and right by site 1. It’s a big site so we put four tents and 15 people on that site comfortably, it also has a covered pavilion which helped us in the rain and a brief storm. The park hosts were incredibly kind and welcoming. One last note, you do need to bring your own drinking water in. We had such a great time and would totally recommend the park for adults or families. My only complaint was the persistent barking dog on the private residence by the entrance to the park, including late at night.
