After several successful seasons of springtime operations, Rail Explorers, the family-friendly, outdoor-adventure attraction featuring pedal-powered rail bikes, began year-round tours in October 2019. Located in Boulder City, Nevada, Rail Explorers offers exhilarating, guided excursions in two- or four-seat rail bikes along the same tracks used during construction of the dam. All rides start at the Nevada State Railroad Museum and continue downhill to Railroad Pass.
