My family and I did about 2 miles of this, ages 8 & 9 and grandmother. Easy walk by a stream, however, we went after the rain and it was like a river. The river actually made it impossible to pass at the 2 mile mark without getting wet up your knees. So we turned around. Can't wait to come back

My 4 kids and I went up with our mountain bikes and had a blast. Definitely loved the terrain. Water streams strong and high thanks to all the rain. So be ready to get wet and push through.

The description above states that this is a 20 mile moderate hike. However, the group I went with today took the cutoff to Paul Little camp ground and the trail ended at a man made dam/waterfall, which is less than half that distance round trip, and it is an easy fairly level trail.

After years of being a couch potato, I started hiking again only about a month ago, and have bad knees and bad back, so the group pace was a bit fast for me. The furthest I had gone previously was 5 miles, so I thought the touted 7 mile round trip would be a sizable jump for me. However, it turned out that from my car in the middle of the lot till I got back to it exactly 4 hours later is, according to my pedometer app, 9.7 miles, which was a huge jump for me. Granted that towards the end my steps were probably getting a bit shorter, but I still guesstimate that the distance was probably between 9 and 9.5 miles. Probably closer to 9.5. I figure that I was at least 20 minutes behind the group, since I got a text about 15 minutes before I got to the car, from one of my carpoolers that they were taking Uber.

I highly recommend this trail for beginning hikers and those like me who have injuries. I also recommend that they go at their own pace rather than trying to keep up with a group of people, unless that group consists of equally slow hikers. I wish I could find a group like that.
