Our Heritage

In 1969, three intrepid mountaineer-explorers, Leo Le Bon, Allen Steck, and Barry Bishop, came up with a then-radical idea: to create a business out of their incurable wanderlust for global adventure, sharing backcountry wilderness trips to remote areas where foot travel was the only means of access. Their venture was called Mountain Travel and with it, the business of “adventure travel” was born. Around the same time, Richard Bangs, Lew Greenwald and John Yost were rafting first descents of rivers across the globe. In 1973 they formed Sobek Expeditions—an international rafting company named after the ancient Egyptian god of crocodiles.

For the next two decades, each flourished on its own—earning word-renown as a leader in the adventure travel industry. In 1991, the two companies joined forces, becoming Mountain Travel Sobek, offering the world’s single largest selection of active adventure journeys across the globe.

In 2019, MT Sobek turns 50 and our deep passion for adventure is as strong today as it was in ’69. We are proud of our adventure travel legacy and thankful to our founders, guides, and intrepid guests who have helped craft the adventure company of today.
