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.

Along with 10 different trails including the popular Storybook Trail, the park has a public rock climbing and rappelling area. Clifton Gorge State Nature Preserve, located next to the park, offers additional hiking opportunities. (Note: pets are only permitted in the park, not in the preserve.)

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