Approaching the tracks.As we get nearer to the end of the trail, it becomes narrow and rocky. Slabs of stone and small boulders have fallen from the rock wall onto the trail making it more difficult to ride. If you have a good bike, you'll really get off on the trail action here. Best to walk it if you're lacking in confidence. A head first death plunge would unnecessarily burden those traveling with you.

At last, the other end.
Finally!
The end of the trail.
That was gnarly, dude!
I've got to try this again sometime!
We encountered a couple of guys on motorcycles while we were riding.
They were trying to get past the fallen boulders.

Collapsed tunnel entrance.The tracks emerge from the rubble blocking this end of the tunnel. We climbed up to look in, but there's another pile of rocks just inside that goes all the way up to the ceiling. No chance of getting through there. This is one of the obstacles to reopening the line to railcars. If this tunnel were reopened, it would allow access from the highway all the way to the Goat Canyon trestle. The Carrizo Gorge Railway is dedicated to reopening the entire line.
Water tank?Topographic maps show a spring located right up the canyon. We didn't bother looking for it, but there are pipes coming down the hill to this frame. This leads us to belief there was once a water tank located at this spot. Possibly for refilling steam trains as they made their way up through the gorge.
