Our Story

Menu

The difference between a good trip and a great one is often down to the guide—and Nat Hab Expedition Leaders are truly the best!

If you’ve traveled with us, you know your Expedition Leader often makes the difference between a gratifying trip and a truly outstanding adventure. Simply put, the guides who lead our trips are the best in the business. Painstakingly selected, these highly trained professionals bring a set of traits that foster a superlative travel experience. They are passionate about the places they share with their guests, with an irrepressible enthusiasm that can’t help but inspire those who travel with them. As naturalists, biologists and environmental educators, their knowledge deeply enriches our guests' experience. They receive in-depth training plus exclusive resources from World Wildlife Fund's team of scientists. While many of them hold master’s or doctorate degrees, they are chosen for their good nature as well as their good grades. Many of our guests are global travel veterans, sophisticated and independent—but they choose to go with us because of the consistent top-quality leadership on our trips. In the realm of nature travel, great guides set us apart.
