Greg Witt has lived the adventures he writes about and shares with audiences around the world. His journeys have taken him to every corner of the globe. He has guided mountaineering expeditions in the Alps and Andes and paddled wild rivers in the Americas. He has dropped teams of adventurers into golden slot canyons, trudged through deep jungles in Africa, Central America, and Asia, and guided archeological expeditions across the parched Arabian Peninsula. His passion for adventure has always focused on sharing his experience with others. Greg is the founder and Chief Adventure Officer of Alpenwild, the leading operator of hiking and trekking tours in the Swiss Alps. Some weeks, Greg hikes more miles than he drives, which means he wears out his boots faster than he wears out his tires. He has crossed the Grand Canyon on foot many times, climbed Colorado's three highest peaks in three days, and in a recent summer in the Alps he hiked over 700 miles and gained nearly 100,000 vertical feet of elevation-the equivalent of climbing Everest 9 times. Now he leads readers on the most breathtaking hikes and exciting outdoor adventures on the globe. He comes ready to discuss the geology, history, archaeology, weather patterns, culture, flora, and fauna of the exciting locales he loves. Other titles include "60 Hikes within 60 Miles: Salt Lake City" and "Ultimate Adventures: A Rough Guide to Adventure Travel." He is the US Editor of "Off the Tourist Trail: 1000 Unexpected Travel Alternatives" and a contributing editor of "Make the Most of Your Time on Earth: A Rough Guide to the World." He lives in Provo, UT.
