Harnessing yourself to a rope and rappelling into a canyon is challenging enough--but what if on the way down, you run into a waterfall? Since 1999, ATS AdventureWorks has prepared students for exactly this type of outdoor challenge, with courses in canyoneering, mountaineering, and rock climbing. Adventurers can also try their hand at these vertical sports on the company's indoor ropes courses, or on guided trips to rock formations and climbable celebrity homes throughout Southern California. The company's veteran team oversees every outing and class, keeping novices safe and sharing tips on gear and safety. And even when they're not working with students, they're navigating rough terrain and setting up specialty TV rigging for shows such The Amazing Race, The Bachelor, and The Biggest Loser.
