Accompanied by local conservationists and expert wildlife biologists, join us for a living lesson on the ecology and conservation of one of North America’s most iconic species: the monarch butterfly. Each year as winter gives way to spring, monarchs leave the safety of their wintering grounds in central Mexico and fly north to places such as Texas or Louisiana. They mate, lay eggs on milkweed plants, and die. The caterpillars hatch, form a chrysalis, and emerge as butterflies, ready to continue journeying north. It takes four or five generations before monarch butterflies arrive in the northeastern U.S. and Canada by summertime, each hatching, living, and dying in just six or seven weeks. Then, the last generation—a single “super generation” of butterflies—flies 3,000 miles back to Mexico, where they spend the winter in the very same forests inhabited by their great, great, great, great (you get the idea) grandparents just one year earlier. Nobody really knows why the monarchs migrate this way, or how they know where to go—but one thing we do know is that the best place to witness this grand spectacle of nature is at the start of the journey, among the “sacred” oyamel fir trees of Central Mexico.

Trip Leaders

Phil Torres
Phil Torres has been bitten by an anaconda, tackled a tiger shark, and gotten lost in a forest full of quicksand… all in the name of science. As a researcher and science communicator, he spent two years living in the Amazon and has worked in Mongolia, Venezuela, Sweden, the Bahamas, the Arctic, and the bottom of the ocean. He is the creator and host of The Jungle Diaries and has hosted more than 70 episodes of TechKnow on Al Jazeera. He also hosts Ready, Set, Pet on The CW network and Big Metal Bird for United Airlines. Phil has made several significant discoveries as a field biologist in South America, including the decoy spider, a thieving butterfly, and silkhenge; this research and wildlife photography has been featured by National Geographic, Wired, and the BBC. He’s been leading wildlife trips with Atlas Obscura since 2017.
Becky Friesen
Becky is a field biologist from Alberta, Canada. She has worked on research projects across the Americas, from studying hummingbird foraging behavior in the Rocky Mountains to monitoring frog populations in the cloud forests of Honduras to trapping butterflies in Peru's Amazon rainforest. In 2019 Becky obtained her Masters in Forest Science from the Universidad Autónoma de Nuevo León in northeast Mexico where she studied butterfly response to forest fire in an area that sits along the migration pathway of monarch butterflies. She is passionate about conservation and loves to travel, meet new people and talk about wildlife!

Seeing so many butterflies in one place is extraordinary! Sitting quietly and waiting for the butterflies to warm up was my favorite experience. Watching them transform from drab butterfly pine cones to a beautiful whirlwind of orange in the morning sun is an unforgettable experience. The delicate rustle of thousands of wings, like a gentle breeze through the treetops, heightened the sense of wonder.

Trip FAQ

The International Ecotourism Society has formally defined ecotourism as “responsible travel to natural areas that conserves the environment, sustains the well-being of the local people, and involves interpretation and education.” In other words, it is an effort to combine sustainable travel with ecosystem-level conservation and the explicit recognition of and respect for the rights of indigenous people. That’s why ecotourism is more than just “nature tourism." It has the explicit goal of benefiting local communities both environmentally and economically. By providing financial incentives through tourism, these communities can become empowered to fight against poverty. By achieving more sustainable economic development, such communities can better resist exploitative industries such as mining, agriculture, ranching, or logging. Ecotourism has also motivated the traditional tourism industry in general to move toward more “green” or sustainable practices.
