The historic district covers most of central Boulder City and is the most complete surviving example of a 1930s American government town. The streets are laid out in a sweeping arc along the contours of the hill, the houses are small bungalows in pale stucco, and the public buildings — the post office, the Bureau of Reclamation building, the Municipal Building — are arranged around a triangular green called the Wilbur Square. It is on the National Register of Historic Places.
A self-guided walking tour map is available free from the visitor centre on Nevada Way. The walk takes about an hour and includes the original dormitories that housed the dam workers, the wood-frame "Six Companies" cottages, and the Boulder Dam Hotel. The whole district is a flat fifteen-minute stroll, mostly shaded by mature trees — a rare combination in southern Nevada.
