Nice hike, the vegetation changes are really interesting. It's pretty shaded most of the way so not a bad one to do in the summer. Watch out for losing the trail as it crosses the stream, I've almost done that twice now. Randy Beck (289) over 1 year ago N/A: 8 Completed 7 Reviews The beginning of this trail is kindof different, winding uphill of a house with weird sounding animals. Then the trail gets into the woods and is really nice. There are a few places where the trail is washed out, but it just makes it more exciting. We only made it about half way up (2.5 miles) and the sun went down and got a little chilly. We'll make it the rest of the way and update this review in a few days. There are a few trails that branch off, and I'm not certain which one is which, but they're probably all good trails. Nice little parking lot at the trailhead.
