Already one of Los Cabos' most adrenaline-pumping outdoor activities, Cabo Adventures has upped the ante by adding a longer, higher, and faster zip line to their canopy course. The concluding run now stretches nearly a third of a mile in length, and would-be mountaineers can reach speeds of up to forty miles an hour as they race hundreds of feet above the canyon floor, an exhilarating finish to what was already a thrill-packed excursion.

Zip lining has become one of the most popular action-oriented activities for both adrenaline junkies and eco-travelers, and combines an introduction to the local topography with a level of physical exertion that will satisfy even the most seasoned outdoorsmen. Although zip lining tours are a rather recent phenomenon, the activity has a long and distinguished history in mountaineering areas, where lines were hooked up at enough of an angle that gravity could pull intrepid climbers over difficult or impassable terrain, from gorges to snowbanks.

Cabo Adventures has staked out a demanding course in the Boca de Sierra, a UNESCO protected biosphere that lies in the foothills of the Sierra de la Laguna, the mountain range that runs up the spine of Baja California Sur. The company's crack crew run participants through a safety course before taking them out on the actual course, which includes a succession of challenging obstacles such as swinging bridges, crazy ladders, Tarzan swings, and some basic rappelling descents.

The zip lines are the easiest part of the course, in terms of physical exertion, but are the highlight for most visitors, with a half dozen lines providing high-speed, high-altitude thrill rides. The tour is available on a daily basis, and includes bottled water and light snacks.
