When good weather arrives, it's time to head outside. But what if you're tired of the same old, tame old wilderness pursuits like hiking, biking and tent camping? Well, hold on to your hats (and boots and backpacks, too). Here are some bold open-air diversions — like sky diving, below — that let you enjoy nature to the extreme. Just don't try them without proper training, robust equipment and plenty of "leave no trace" respect for the places you pass through.
Intrepid outdoor adventurers often hope to conquer a mountain peak or two in their lifetimes, but peakbaggers take mountain climbing to a whole new level. These goal-oriented extremists aren't necessarily aiming for the highest peaks — rather they're all about quantity (i.e., putting as many peaks "in the bag" as possible). Munro baggers, for instance, strive to climb all 283 Munros in the Scottish Highlands (the highest is 4,409 feet). To up the competition, some try to "bag" as many peaks as possible in a day or scale every peak in record time. Name a mountain range and there's probably a group of baggers — e.g., the Adirondack Forty-Sixers, the California Thirteeners, British Columbia's North Shore baggers, and even a group of fledgling New Zealand baggers.
Gorillas do it, chimpanzees do it, and now you can, too. For treehuggers seeking a taste of their evolutionary past and some arboreal-induced Z's, several canopy-camping tour operators now let you climb into the treetops and snooze among the leaves. Granted, you get a specially made hammock rather than building your own nest, and most tour operators offer gourmet meals and other amenities, but this primal experience is sure to help bring out your inner primate. If nothing else, hanging far above the relentless rush of modern life may score you your first decent night's sleep in years.
