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 archaeological expeditions across the parched Arabian Peninsula.

After earning degrees from the University of California and Brigham Young University, Greg had an early career in human-resources management. Preferring high adventure to the high-rise, he traded his wingtips for hiking boots decades ago and has never looked back.

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 more than a dozen times and climbed Colorado's three highest peaks in three days. Each summer in the Swiss Alps, he hikes more than 700 miles and gains nearly 100,000 vertical feet of elevation as he guides guests of Alpenwild (alpenwild.com), a company he owns and operates.

Greg loves leading 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. His other books include Exploring Havasupai (Menasha Ridge Press), Ultimate Adventures: A Rough Guide to Adventure Travel (Rough Guides), and 50 Best Short Hikes: Utah's National Parks (Wilderness Press).

Greg's research and exploration continue to uncover adventures just waiting to be experienced. If you join him, you'll be guaranteed a phenomenal journey.
