Calico is an old mountainside mining town that was abandoned when the 19th-century silver rush dried up. Its buildings were preserved and restored by the same family behind Knott's Berry Farm, who reopened it to the public as Calico Ghost Town. Drive in, pay a small fee at the gate, and explore what it was like to live in the late 1800s -- give or take. In between the wooden signs and wagon wheels, you can explore the old schoolhouse, barber shop, and other businesses from back in the day. A few attractions cost a little extra, like the self-guided mine tour and the Mystery Shack, an optical illusion of space and perspective where water runs uphill. The best way to soak everything in is on the Calico Odessa Railroad, a train that circles the park in about eight minutes. Open daily 9am-5pm with ghost tours after dark on Saturdays, the attraction also features a campground and has spaces for tents and RVs.
