Last weekend we drove up to Donner Summit and hiked around the old train tunnels. They were awesome! The kiddos got to wear their head lamps and the views were stunning! The tunnels were dark and cold and had tons of graffiti and art painted all over them. Good thing the younger kiddos can't read yet.... ha! The views of the mountains and the lake were amazing as well. This is definitely a hike that we will be doing again in the future.
