Travel and Learn with IHO

Immerse yourself in the span of human history with engaging scientists and a rich understanding of history

Educational Travel At Its Best

The Institute of Human Origins has a long history of research in Africa and the world to understand the course and timing of human development—the history of how we “became human.” This is our human history, and we believe that sharing this knowledge with the public is as important as sharing the science.

Our expeditions are different from any other travel experience. This is not just travel—it is immersion in the span of human history, hosted by IHO and ASU scientists who add a richer understanding to the travel experience.

At the same time, our travel adventures have been designed for fun, excitement, and comfort and take advantage of the best accommodations and sailing vessels available in the industry. We partner with top travel providers who are specialists in exotic areas of the world.

Plus, tour leaders, like Don Johanson and other IHO scientists, have been accompanying our travelers since the 1980s to Ethiopia, France, Galapagos, Madagascar, South Africa, and Tanzania, and as well as being seasoned world travelers themselves. With years of experience, we understand the balance between a great travel experience and a rich learning program.
