Last weekend Colin found out they removed the tracks & trains don't run through there, so it's turned into a graffiti museum that anyone can hike through... And with the dogs in tow- we made our way up there.
The first tunnel was a little (okay, a lot) sketchy. Dark & very icy! We couldnt even walk in the center of the tunnel. There were mini lakes 3 feet deep Filled with chunky ice water. I learned my boots are NOT water proof :/ brrrr
There are a series of 6 or 7 tunnels that spam the entire length of Donner Lake- probably 5-6 miles if I had to guess. We made it through 3. After the first one, the rest were just dark & a little icy.
And once again, we found some views that don't suck
