About Riordan Mansion State Historic Park

A duplex mansion built for lumber barons Timothy and Michael Riordan stands at the center of this site, bordering Northern Arizona University. The park preserves that log-and-stone residence as its focus, kept as a record of the two brothers who built their fortune in the timber trade. The grounds sit alongside the university campus rather than in open wilderness.

Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
