My wife and I took our three kid, our 1 yr old girl, and 3 & 6 yr old boys they lover it. We started at mile marker 20 hiked down to 17 and back again, so six miles total, and three hours.  i give it a difficulty of 3. becuse of two kids in the jogging stroller, one in a kiddo back pack, and walking our dog. it dose go up and down hills. Nothing too steep though. the creek and bridge about half way down was a nice stopping area for us and the dog. She went swimming while the kids looked through the clear water at the small fish. great lake viewsa throught the trees also. Negitives: lots of over growth through out. may down trees, but cut so the path goes through it and you dont have to go around.  good hike cant wait to try another...
