John Bryan State Park

Beautiful year-round, the park's breathtaking scenery attracts visitors every season. John Bryan State Park is distinguished by its remarkable limestone gorge, which the Little Miami State and National Scenic River cut many years ago. The gorge, a National Natural Landmark, offers hikers splendid views from the trail. A launch area outside the park provides paddlers with access to the river.

Along with ten different hiking trails, including the popular Storybook Trail, the park has a public rock climbing and rappelling area and miles of mountain bike trails. Clifton Gorge State Nature Preserve, adjacent to the park, offers additional hiking opportunities. (Note: Pets are permitted in the park, but not in the preserve.)

Day-use visitors will enjoy the scenic picnic areas and playground. A reservable day lodge is great for group gatherings. The family-friendly campground is perfect for overnight guests who enjoy semi-rustic surroundings.



A paddlecraft launch area near the park on Jacoby Road provides access to the Little Miami State and National Scenic River. As the river twists and bends, visitors will discover steep rock cliffs, towering sycamores, and many historic sites along the way.


The John Bryan State Park Campground offers non-electric and electric sites close to the park's hiking trails. Pets are permitted on all sites. The park also offers a group camp. Reservations may be made six months in advance online or by calling (866) 644-6727.

All climbers are encouraged to use safe climbing practices. Top-rope climbing is permitted from dawn to dusk. Bouldering is prohibited.

Storybook Trail

Located beside our newly installed playground, this Storybook Trail presents a children’s nature story in segments along a short path.

At the beginning of the trail is a free Little Library where you can choose to take a book home or leave one for others.

Winter Recreation

Under the proper winter conditions, park guests can enjoy sledding near the lower shelter house and cross-country skiing.

History & Natural Features


Some of the first people to experience the area's beauty were the Moundbuilders, and later, the Shawnee Native Americans. Just 5 miles south of Yellow Springs, approximately where the town of Oldtown is now, was the site of Old Chillicothe, one of the leading Shawnee settlements in Ohio. The great Shawnee warrior, Tecumseh, was a frequent visitor here and at the nearby James Galloway House, which is maintained by the Greene County Historical Society.

This portion of the Little Miami River was a vital, economical source of power for the early European settlers in the 1800s. The Cincinnati-Pittsburgh stagecoach road served the area and several enterprising settlers began establishing water-powered industries in the gorge. The town of Clifton prospered from its textile mill, grist mills, and sawmills. By the late 1800s, water was no longer an economical source of power and many mills were abandoned. Today, Clifton Mill, a nearby grist mill built in 1802, is still in operation and is open to visitors.

The park takes its name from businessman John Bryan who was responsible for the preservation of much of the area as a state preserve. In 1896, Bryan purchased 335 acres along the gorge and called these acres, "Riverside Farm."

Bryan had a great respect for the natural world. In 1918, he bequeathed Riverside Farm to the state of Ohio, "...to be cultivated by the state as a forestry, botanic and wildlife reserve park and experiment station," which would bear his name. In May of 1925, John Bryan's land became one of the state's first forest parks. In 1949, John Bryan State Park was transferred to the newly created ODNR Division of Parks and Recreation. John Bryan State Park and the adjoining Clifton Gorge State Nature Preserve overlook the beautiful Little Miami River gorge that has been designated as a National Natural Landmark by the U.S. Department of the Interior.

Natural Features

Much of the history of John Bryan State Park is "written in the rocks" of the Little Miami River gorge. Entering the area at Clifton, at 980 feet above sea level, the Little Miami drops 130 feet through layer upon layer of limestone and shale bedrock. Each layer has a tells a story of the time when the area was covered by warm, shallow seas or scoured by tons of slow-moving glacial ice. Each layer has its own characteristics. Some of the shale layers are easily worn away by the forces of erosion, causing undercutting in the cliff face. The more erosion-resistant dolomite and limestone rocks above are weakened by this undercutting and large "slump blocks" fall away, creating unusual rock formations including Steamboat Rock (which can be see at the preserve). Springs feeding small waterfalls and cascades are common.

Geology of Clifton Gorge State Nature Preserve and John Bryan State Park

Not only did the glaciers affect the landscape, but they also affected vegetation. As the last glacier retreated and the climate warmed, the cool shaded recesses of the gorge valley provided a suitable habitat for several Canadian plant species such as Canada yew, redberry elder, mountain maple, arborvitae,and even a few hemlocks.

More than 100 different trees and shrubs have been identified in the park. More than 340 species of wildflowers grow wild here. Snow trillium, Virginia bluebells, bellwort, wild ginger, Dutchman's breeches, Jack-in-the-pulpit, and wild columbines are only a few to be seen in the park. The dominating trees are oaks and maples, but large numbers of sycamores and cottonwoods can be found along the river. Wildlife is also abundant in the park. For instance, more than 90 different varieties of birds live in or visit the park area during the year. To fully appreciate the beauty of John Bryan, one needs to experience it during all four seasons.
