If it is dry, the long loop is fun and can be done in around an hour. This is a good local trail, but not one I would drive too far to ride. It was my first REAL trail, and I was a beginner. I survived, and I go about 2-3 times a week now. A graveyard that's at least 130 years old, and a possible Native American Burial Site.
Mile markers are up and a map is posted at the start.
The creek crossing at mile maker 4.0-4.4 has a new trail that will keep you from having to go through what I call Bubble Gum Alley with all the rain. I've been riding this trail for 8 years and it is in great shape. If you would like one of my maps, I can send one in about any format you wish. Tour de Dump is the closest trail for me. I really like riding it and it is very fun.
