We rode this trail a couple of weeks ago and it is labeled with signs as an ATV trail. Most of it, was okay for mountain bike riding, but there was a section of it that was pretty tore up due to the ATV travel. Since the trail is along the highway, we took a side road and rode along the highway for a few miles. The trestle bridges are pretty awesome and the view of Agate Falls is great. The park at Agate Falls is a great place to take a break as there are picnic tables and a bathroom. The park is on the other side of the highway, but there is a trail that goes under the road bridge to get there. Other than the roughness of the trail and that we shared it with a few ATV's, the trail was okay overall. We'll not do it again, however as it is no fun to ride with ATV's.
