While our most popular types of group tours are special interest groups like birding clubs/Audubon chapters, professional photographers, or botanical gardens, we also work with numerous museums, zoos, aquariums, and other natural history organizations. These tours usually include a mix of formal and informal lectures and workshops related to your topic of choice, and are escorted by a qualified U.S. leader (someone from your organization) and an expert local guide. Travel is a unique and effective way to fundraise, build your membership, and connect with your donors! 

With expert programming and leadership, Holbrook’s natural history tours take travelers from ancient civilizations to ecological reserves, from the dynamic arts and society of the city to the sounds of songbirds or howler monkeys. We believe that natural history tours should not just inform, but engage, enliven, and enlighten travelers as they journey to some of the world’s most remarkable regions.

Since 1974, we’ve made connections with experts around the world, allowing our travelers special insider access and behind-the-scenes experiences that are typically unavailable to the public. Because of this heritage, we include aspects of natural history programming in nearly every expedition that we develop.

We’re committed to adhering to the best practices of ethical and sustainable tourism and providing travel opportunities that respect and protect the environment. Our customizable natural history tours highlight the interwoven elements of a country’s biological and social systems, from ecology and conservation to history, culture, and education.
