Tintic Railroad Tunnel

Also known as the Elbert Slant Railroad Tunnel, this abandoned railroad tunnel is a fun spot to explore. The tunnel is about 235 feet long and can be driven through by most passenger vehicles.  The road to the tunnel is a bit rough, and high clearance is recommended (though we've seen minivans and small sedans at the tunnel before). The road can be very muddy in wet conditions, so do not attempt a visit unless the roads are dry.

The best way to get there is to follow Google Maps, then once you're there, switch to satellite view and follow the path marked in green here:

We typically go through the tunnel, turn around and go back through the other direction. The road loops around and takes you back to the other side of the tunnel, but you might as well go through twice :).
