Tidioute Riverside RecTrek Trail

nice walking trail

June, 2026 by melgraves70

The trail is a nice walk and mostly in the shade. Great for walking but not for biking. There are a lot of tree roots. Great place to walk your dogs.

David S Ammerman Trail

May, 2026 by n1960burbank

We just got back from riding this trail. We had hybrid bikes and experienced no problems. The trail was well marked. The last 3 miles was all uphill so bring plenty of water. We rode onThursday and there was very little bike traffic. All in all a very nice trail well maintained and would recommend a visit.

West Creek Recreational Trail

Very nice trail!

September, 2025 by hartt20

Rode out 11 miles from Emporium toward St. Mary's (~22 miles RT). Beautiful scenery once you get out town. Several interpretive signs explaining the environment and history of the area. The trail is surface is mostly packed crush stone and is well maintained. Would definitely do this one again.

Five Bridges Trail

Rough.. big gravel ..but beautiful. So much wildlife. Beaver dams. A bear jumped on the trail in front of me about 50 yards.. I just waited as he walked away from me.

Clarion-Little Toby Trail

Nice Trail- has some deep water holes

July, 2025 by carebare552

This trail goes through state game lands, is mostly shady and parallels an active railway. The active railway portion has some deep mudholes. It would be wise to start at Ridgeway as it is uphill to Brockway.

A shady path for a heat intensive day!

Knox & Kane Rail Trail

Knox Kane Trail

July, 2025 by carebare552

Started at Kane. The trail was unmaintained after mile 4.7. I then went to the Kinzua bridge state park and rode to 219. A nice trail

Mahoning Shadow Trail

Mahoning Shadow is a beautiful ride

June, 2025 by lorainer

We stayed in Punxsutawney and could access the trail from our B and B. We rode east to Winslow, an uphill grade but doable on our e-bikes. Saw chipmunks, squirrels and a very long black snake crossing the trail. After a break for lunch in town we rode west to the Fordham trailhead. Several interesting sights along the way- the coke ovens, a couple Minions and another snake. The trail is wide 8-12’ with a cinder surface with no roots or potholes the whole length. Total 16 miles on a shady trail, sometimes along the Mahoning Creek. I bet it’s gorgeous in the Fall.
