I have been on this trail one time, and I'll never forget it. This trail is full of history, and is very easy to ride. It is nicely paved and maintained, especially between the months of Late April to September. Don't be surprised at all if you find a few deer on the trail. Because of the close proximity to Oil creek, in the mid spring you will find the Red Eft newts walking across the trail, a beautiful creature. When biking with my friend Bruce, we both came within about 75 feet of what appeared to be a lynx or small bobcat. This trail winds parallel to the historic Oil Creek watershed. I put in at Oil City and went to historic Petroleum. About 9.5 miles one way. Once a booming Oil town of approximately 5,000 people in the mid 1800's, you'll be able to see the foundations of the now ruined hotel foundation in Petroleum. Information signs show where everything was. Some people don't know, but there is an old cemetary just off the bike trail near Petroleum, by where the old hotel was. Ask the Petroleum Park desk where to find the old cemetary, very helpful and informative people. This was a very fun trip. I would highly recommend it for a day away from the daily routine or for a fun family cruise.
