This historical railroad trail is located in Boulder City, Nevada along the Lake Mead. It is called historic railroad trail is because it used to be a railroad track that brings materials to build the mighty Hoover Dam. Now it has become one of the most beautiful and nice walks in Southern Nevada. The trail is completely flat with the exception of the beginning after parking. There is several tunnels that you will go thru during your time on the trail. I am afraid of little darkness in the tunnels but once I enter, all the fear goes away. It is sort of like Bruce Wayne entering the bat cave and then feels like home.
