There are 6.5 miles of mountain biking trails at John Bryan State Park. The trails were built and are maintained by the Miami Valley Mountain Bike Association in partnership with the Park. The first trail, Power Line, opened in April 2002. The other two trails, Abracadabra and Great Scott, opened in April 2003. More trail was added early in 2004.

• Power Line is 1.2 miles of tight twisty turns with some creek crossings, a balance beam & one small ramp. Power Line is located on the outside of the Arboretum trail. It is perfect for honing bike balance & turning skills.
• Abracadabra is a 2 mile section which is flat and open for easy riding. It has one medium-sized ramp (with a chicken run around it) and a creek crossing. Abracadabra is located inside the Arboretum trail loop.
• Great Scott is the longest trail at about 3 miles and has some small climbs, creek crossings and the biggest ramp (with a chicken run around it). It consists of Upper Great Scott (from the entrance, located across from the Abracadabra exit, to the big ramp), Lower Great Scott (from the big ramp to the bridge) and the Great Scott Loop (from the big creek out to the end and back to the big creek).

All trails have some log jumps and the creek crossings may be wet or dry depending on the weather.

Trails are marked with signs. Watch for arrows showing the recommended route at intersections. The map shows all trails.

Please help us track trail usage by signing the Trail User Log at the Arboretum trailhead kiosk. The kiosk has trail maps and other Park information. If you enjoy these trails, please pass along your comments to the Park staff.

RULES FOR USING THE TRAILS

These trails were built for mountain biking but are open to hikers as well. Bikers should always yield to hikers.

The following guidelines are from the International Mountain Biking Association (IMBA):

Ride on open trails only. This means no riding on wet or muddy trails. You leave ruts and ruts hold water. Please allow 2 full days after a good rain for the trail to dry out.

1. Leave no trace. Pack out all of your trash and don't rut the trail. (See Above).
2. Control your bike. Ride within your limits so you don't endanger anyone else.
3. Always yield trail. Bikes must yield to hikers, walkers and those on horseback.
4. Never scare animals.
5. Plan ahead. Try to anticipate what will happen next.
6. Always wear a helmet No one wants to drag you out of the woods.
7. Remember, these trails belong to everyone.
