If you have ever wondered how this immense dam was built, then this tour is a great way of exploring this remarkable civil engineering landmark. Standing at over 700 feet tall, it has the capacity to irrigate two million acres and provides power to southern California, Nevada and Arizona. Enjoy exploring the power plant and head out onto the observation deck outside to walk along the dam itself (no James Bond moments please!) with panoramic views of Lake Mead, the largest man made reservoir in the USA and the mighty Colorado River. The fascinating Boulder Dam Museum, the visitors centre and auditorium also feature in the tour before heading back to your Las Vegas hotel in comfortable, air-conditioned vehicles.
