Old Mormon Fort State Park

It may be the only state park in the United States that is actually within someone's city limits: The Old Mormon Fort State Park at the intersection of North Las Vegas and East Washington. It includes remnants of the original adobe structure built by Mormon missionaries in 1855 during their short-lived tenure in the valley. Hours are 8 a.m.-4:30 p.m. Tuesday through Saturday, and admission is only $1, with kids 12 and under getting in free.
