Agree with mountainmanmark, a nice and quiet alternative with good vistas. Ran into a blizzard so were pleased to finally find the train tracks which we followed to the top. Amazingly we found people walking around in shorts and high heels when we got there!!!
Good alternative route to the others as it tends to be considerably less crowded, good views to. I think it is only once up and on a separate occasion once down and thats all for this one.
