Age is nothing but a number at the Generations Hike. Bring the whole family out to Greenleaf State Park and celebrate 80 years of Oklahoma State Parks with a special group hike that will connect generations in the great outdoors. The hike will take place on the park's Family Fun Trail, so everyone can participate. This 1.5-mile, paved, beginner-level hiking trail is wheelchair-accessible and begins at the Greenleaf State Park office. Along the trail, you'll find benches, a gazebo and other places you can stop to rest, including an observation deck that overlooks the Arkansas River. Travel through wooded areas, near the children's pond and around structures built by the Civilian Conservation Corps, and make sure to check out the informative markers along the way during this fun family hike at Greenleaf State Park.
