For more of an adrenaline kick, Absolute Adventures—Shark Diver offers trips from San Diego to the coast of Baja, where divers don scuba gear before being lowered in cages to observe great whites. The package includes a videographer, gourmet meals and accommodations on an expedition yacht ($100,000 a week; sharkdivers.com).
Have only a few hours? On the one-day “Blue Mountains Wilderness, Wildlife Park” tour in Australia, visitors can feed kangaroos and cuddle koalas at a wildlife park ($130; sydneywildernesstours.com .au). In Dubai, you can bond with dromedaries on a camel trek into the desert (from $90; nettoursdubai .com). You may never settle for the zoo again.
