amazing trail. lots of fun, wildlife, water

very nice trails not well marked at all very easy to get lost.

great hike, but the trail isn't well marked and it's very easy to get lost and end up on private property

Trail not well maintained and very muddy. Not well marked and goes through the middle of a kids camp. Do not think I will go back, many other better options.

About half the hike is akin Bull Run river...very nice. About 1/3 of the hike is over rocks so just be advised. Went with my dog and he enjoyed it as well!
