World Class Guides

International Expeditions is the world leader in nature travel for one reason above all others — we feature only the best travel guides—the superb, English-speaking naturalists and historians who accompany you. While our destinations are remarkable in their own right, they become even more so because of the talented world travel guides who breathe life into the details and encourage you to discover. Not just ordinary “tour leaders,” our travel tour guides are consummate local experts with the uncanny ability to tell you about all the animals, plants, history and culture you encounter along the way. More than that, they are also warm people who want to see that you get the most from your expedition. Because of them, your International Expeditions journey will be interesting, enriching, memorable and great fun.

Below are just a few of our many travel guides and expedition leaders who enrich our expeditions. Find more about each destination’s guides on the expedition Web pages.
