The Donner Train tunnels are a fun day trip from Sacramento. Located near Donner Ski Ranch one can hike through one tunnel or all of the tunnels for about an eight to nine mile trek if you go the distance. It gets pretty damp, dark and cold so be prepared. Last year we went and everything was covered in snow and ice with monstrous ice cycles. This year we managed to visit right before Halloween and before the first real snow of the season. Lots of art can be seen although none too noteworthy. I found the patterns of the ceilings to be interesting and the tunnel lighting to be fun. This was a great socially distant COVID day trip/hike.
