the trails are pretty clearly marked, which way you go is up to you, my buddies and i ride the trails both ways for more miles, experience and just for somthing different.
there are some intermediate trails throughout, also some very technical climbs, on the one trail there is a pretty sweet rock wall we always spend some extra time trying to see how high we can go on it taking cool pics and laughing when we fall off of it.
there are tons of bridges and some log rides.
there is a lot of climbing so this is not a great winter trail when you get a couple of inches of snow it makes for a very difficult ride, i don't mean challenging its just not fun.
starting from the intersection of route 22 and 66 just outside of Murrysville/Delmont<br /><br />Head north on 66 until you get into Apollo go across the bridge in town and at the very first light turn right you will pass the Mozey Inn on your right and Patricks Pub on your left (both good spots for a post ride brew) <br /><br />follow the very narrow road all the way to the end and you will hit a parking lot, here you will find the rail trail start down it and the trails are all over on your left opposite the river.
