The Bottom Yough is beautiful. You can put in at Connellsville and take out at Cedar Creek Park. Makes for a great 1 night 22 mile trip or you can go further downstream to get 2 nights in. There are designated campsites for the boaters & bikers on the bike trail that parallels the river. The only downside to this trip is the busy railroad tracks on the far side of the river. Earplugs are a necessity for sleeping well. Here's a link to the map:
