Great Explorers Go Together

Great Explorers Go Together
Let Us Take You There

While many may think the world has been explored, that all the great journeys have already been undertaken, that is not so. The surface has been skimmed and maps charted, but today’s travelers can delve deeper and still find the sense of wonder and spirit of discovery that drove those first explorers. The world’s most extraordinary destinations are places for learning, for growing, for transforming.

For a combined 65 years, this has always been the ethos of International Expeditions and Zegrahm Expeditions, sister companies dedicated to showing curious travelers the world. Zegrahm and IE have pioneered expedition-style travel to some of the most remote destinations on all seven continents and given explorers like yourself the opportunity to experience authentic cultural encounters, set forth on exhilarating excursions, and make discoveries alongside a team of experts and scientists—all while supporting conservation and community projects around the world.

As pioneers in expedition-style travel, International Expeditions and Zegrahm Expeditions have made it their mission to offer once-in-a-lifetime opportunities to fellow explorers in some of the most remote and emerging destinations around the globe.

Zegrahm Trustpilot Review

We have taken 13 adventures with International Expeditions. We are often asked which trip was our favorite and have never even able to zero in on just one, or two, or even three. All trips were well planned and executed. Our expedition leaders and local guides were superb. We’re currently exploring choices for our 50th Anniversary trip.
