Since I live in the San Francisco metro area, I get a lot of out-of-town visitors. My favorite place to take them is the Exploratorium, along the bayside waterfront. It is the original hands-on science museum, and still the world’s best hands-on learning experience. Many of the interactive exhibits now common at science museums around the world began here; the Exploratorium has all of them and many more found nowhere else. This sprawling temple of innovation and maker-goodness can easily occupy me — even after my 50th visit — for four hours or more. (I normally get saturated after only one hour in other museums.) Of course while it is perfect for kids of all ages, every Thursday evening it’s reserved for adults, and crowded with innovators and artists of all types. — KK

If Burning Man was created by a single eccentric artist, it would be Robolights, a four-acre mind-blowing sculptural landscape in Palm Springs, California, created by Kenny Irwin. It’s the only place I’ve visited that matches the surreal feeling I get from dreams. Free. Open from November to January each year. — MF

The world’s coolest nature museum: The Pitt Rivers Museum in Oxford, England. It’s a day trip from London. Take the 1-hour train to Oxford, then walk 15 minutes from the station to the museum, co-housed with the Oxford University Nature Museum. Enter into a lost world of curiosity. You are surrounded by three floors of artifacts collected over centuries by eccentric British explorers. Displays include shrunken heads, voodoo dolls, tomb relics, weird insects, ancient folk tools, dinosaur skeletons, taxidermy galore, uncountable biological, and mineralogical specimens, all stacked in glassy cabinets with typed cards and labels. It’s supremely old-school and hugely satisfying. — KK
