World's Best Expedition Leaders

If you’ve traveled with us, you know that our Expedition Leaders make the difference between a gratifying trip and a truly superlative adventure. Simply put, our leaders are the best in the business. Painstakingly recruited and selected, this group of highly trained professionals brings a set of traits that foster an outstanding travel experience. They are passionate about the places they share with our guests, and they exude an irrepressible enthusiasm that can’t help but infect those who travel with them. As naturalists, biologists and environmental educators, their knowledge deeply enriches the experience of those who see the natural world through their eyes. While many of our Expedition Leaders have master’s degrees or PhDs, they are also chosen for their good nature as well as their good grades. Many of our guests are veterans of global travel, sophisticated and independent – but they choose to go with us because of our Expedition Leaders’ expertise. In the realm of nature adventure travel, great guides set us apart.
