Heavener State Park is a day-use only park offering group shelters for picnics, picnic tables, outdoor grills, comfort stations, amphitheater, playground, hiking, exploring, and educational programs about the Runestone. Overnight camping can be found in nearby Lake Wister State Park. The park offers a park office, gift shop and interpretative center with educational information.
Plenty of rain prior to our visit meant the waterfall yards from the runestone (and its protective shelter) was in full flow. For me, the waterfall was more interesting than the subject of the park.
The loop to the rune stone is a nice, although short, walk. Plenty of stairs and some wet stones as pavers makes this a trek for the able bodied. For me, this park is not so much a destination as a waypoint...a good place to let the kids get out of the car and stretch their legs.
We did not get to check out any of the parks other nature trails during our brief visit.
