This trail is difficult to get to - slow travel on a winding gravel, washboard road. But so worth the drive! There are a LOT of trestles, two tunnels, and spectacular views. The rental bikes (right at the start of the trail) are great, but fairly expensive - $40 for 4 hours. The entire trail, even at a snail's pace, is not more than 3. But where else would you get the opportunity to see such vistas on a bike - really worth the effort and expense!
