Tunnels make a good backdrop. Zion, UT


Does this count? Natural Bridge. Bryce, UT


Train tunnel #4 of the San Diego and Arizona Railway that crosses the border between
the United States and Mexico. Between Campo and Tecate, CA

The Black Hills

Hint: It's $15 +/- to go through.

I've been on that train. Neat.

The way through the castle... Ore Mountains- Germany

On the KVR (Kettle Valley Railroad) above Kelowna BC

Ok not technically a tunnel (but a bridge) but I like this shot of Thinairthumper coming into Batopilas Mx.

Underneath Hyway 97C on Bear Creek Main in the Okanagan Valley BC

Another tunnel on the KVR line near Kelowna

Abandoned RR tunnel in Arkansas.

Nothing ADV cool like the previous posts, but the Broadway tunnel in SF,

Well my tunnel is quite a bit different than the tunnels I've seen so far as it's a railroad tunnel and is a live tunnel. I was very nervous riding thru it and couldn't help looking behind me while going thru.

The tunnel is about 1/2 mile long and is on a curve so you can't see thru it. It goes thru tunnel hill near Tunnelton, Indiana.

I didn't have the guts to go all the wa to the end of this "tunnel" I'm pretty sure it was a dead end

Here's a really cool train tunnel. I took these pics aboutv 15 years ago when riding across Canada. Maybe one of our Canadian adventurers can help me out here as I can't remember exactly where this was. I do know I was near Banf.

seems the trains could not handle the grade so they tunnel inside the mountain and loop thier way up. The top photo shows the train going in the mountain at the bottom and approaching above. The lower photo shows the train actually crossing over itself. Kind of neat. Lots of tourists were waiting to see this specific train go through, we just happened to show up about 5 minutes before it got there.

Backbone Rock, Damascus, Tn

This train tunnel is in south Alabama. I have a geocache hidden here and run a dualsport ride through here a couple times a year. Finished in 1899 with simple tools, the tunnel is 840 feet long. Now home to lots of little bats.
Plenty of hurricane debri thanks to Ivan and Denise

You can sometimes hear the Bats gnashing their little teeth in here

Hell bent on escaping the L.A. basin...
