Zegrahm Field Leaders: Inspired and Inspiring
We hear it from our passengers time and again: Zegrahm field leaders are out of this world. That’s because we’ve made it our priority from Day One to recruit the top experts in their respective fields. When planning each adventure, both by ship and on land, we strive to assemble the “ultimate dream team” for the destination: marine biologists, ornithologists, geologists, botanists, historians, anthropologists, archaeologists, and dive masters. Zegrahm field leaders are well-known throughout the world; many of them are published writers, authors, and photographers. All are passionate about travel and the world around them. An added plus: They’re also engaging, personable, and caring.
During our small-ship expeditions, you can look forward to an ongoing series of destination lectures, photo presentations, daily recaps, and onshore interactive walks. On land journeys, one or two field experts will share their intimate knowledge of the region, its wildlife and its cultures, while ensuring that you have a smooth and well-rounded expedition experience.
In addition, on many of our trips, a Zegrahm founder or director is part of the expedition team, lending his/her own incredible breadth of experience to the regions we visit.
See below for a look at our world-class expedition team or just visit any destination we visit and review the trip leaders.
