Hop on a four-passenger rail bike to pedal your way on an 8-mile round-trip tour along the historic Boulder Branch Line railroad tracks with views of the desert mountains and valley below. Each tour lasts about 90-120 minutes with a short break at the halfway point. No worries if your foursome needs a little help peddling uphill because the bikes are equipped with electric motors. But those wanting more of an endurance challenge can simply turn off the motor. Visitors can also wander through the Museum Pavilion train car displays. All aboard in Boulder City for a unique family-friendly and age-friendly outdoor adventure!
