EXPLORE AN ARCHITECTURAL WONDER. Built in 1904 by two brothers for their families, the duplex-style Riordan Mansion, part of the Riordan Mansion State Historic Park , is one of the best examples of American Arts and Crafts architecture open to the public today. Guided tours through the home—fitted with the then-cutting-edge technologies of electric lights, central heat, hot and cold running water and telephones— leave on the hour. Self-guided tours of the grounds can be taken any time the park is open. Riordan Mansion State Historic Park, Flagstaff TAKE IN SWEEPING VIEWS OF RED-ROCK BEAUTY.

Lost Dutchman State Park honors a miner whose gold mine remains “lost” to this day, but the real treasure here is the flora, especially during the spring when, depending on the winter’s rainfall, desert wildflowers carpet the base of the Superstition Mountains. Hike the easy Native Plant Trail, the moderate Treasure Loop and Prospector’s View trails or the challenging Siphon Draw to the top of the Flatiron. Book a cabin in the park to stay overnight.

The “Best Haunted Destination in America,” according to USA Today , Yuma Territorial Prison State Historic Park operated as a territorial prison for 33 years, from 1876 until 1909. While the park doesn’t offer ghost tours, it’s rumored some inmates never left. Be prepared to encounter John Ryan, who took his own life in Cell 14, or the spirits of those who endured solitary confinement in the Dark Cell. A little girl is also reported to haunt the park. VENTURE INTO SPECTACULAR CAVES. In 1974, two spelunkers discovered a “living” cave whose formations are still growing in the limestone hills near Benson. Today, Kartchner Caverns State Park offers several half-mile tours inside to see one of the world’s longest soda straw stalactites, a 58-foot column and other extraordinary formations. Stay overnight in one of the park’s cabins, and hike the park’s trails the next morning. The Discovery Center features exhibits on cave formations, cave life, hydrology and history.
