After the daytime spectators have migrated back to South Beach, Miami Metrozoo comes alive. On your personalized tour of animal enclosures, you can hold bearded dragon lizards, pet a rhino on its horn, and watch nocturnal sloth bears suck up raisins like a vacuum. 1 Zoo Boulevard; 305/251-0400; miamimetrozoo.com; from $50 per person; children over six; overnights held several times a year.
More than a million fossils have been pulled out of the museum’s La Brea Tar Pits since 1906. At this "Camp Goo" overnight, get a flashlight tour of the bubbly asphalt they came from. 900 Exposition Boulevard; 213/763-3466; nhm.org; $43 per person; children five and older; overnights held several times a year.
Campers have access to all parts of the museum, but chances are you’ll spend most of your time in Butterfly Haven, a 2,700 square-foot greenhouse where all manner of butterflies sprout wings (look for leopard-like Rice Paper butterflies and Cairns Birdwings from Australia, which can be up to nine inches wide). 2430 N. Cannon Drive; 773/755-5100; naturemuseum.org; $40 per person; children 6-11; overnights held several times a year.
Climb "Mt. Everest"—a disguised spiral staircase—at this Himalayan-focused museum with the help of mountaineer Luis Benitez, who’s summated the real thing six times. Each gallery floor serves as a camp with different real-life climbing challenges, like tying knots with mittens on and using supplementary oxygen. 150 West 17th St; 212/620-5000; rmanyc.org; $108 per person; children 11-13; overnights held once a year.
Wear your craziest-patterned p.j.’s: after you dig for replica dinosaur bones and sleep in the fossil exhibit, Ms. Frizzle—that ginger-haired teacher of Magic Schoolbus fame—will be waking you up for breakfast. 1788 El Prado; 619/232-3821; sdnhm.org; from $55 per person; overnights held several times a year.
