Located in Greene County but within a 30-minute drive from Clinton County. Beautiful year-round, the park's breathtaking scenery attracts visitors in every season. John Bryan is distinguished by its remarkable limestone gorge, which was cut by the Little Miami State and National Scenic River. The gorge, which is a National Natural Landmark, offers hikers splendid views from the trail. A launch area outside the park provides paddlers with access to the river.
