Yellowstone Insight is a continuation of personal guiding services that have been in place since March 1, 1872 when President Ulysses Grant created Yellowstone National Park as the world’s first national park.

The owner, MacNeil Lyons has 20 years of experience guiding and exploring in Yellowstone with a passion for sharing his knowledge of the natural and cultural resources found throughout the Greater Yellowstone Ecosystem. The focus of MacNeil and his company is rooted in the simple concept of instilling an appreciation of preserving the world’s natural resources for future generations.

About MacNeil

MacNeil was raised with an understanding to be grateful for the biological world that surrounded him.  With a nickname like “bird”, given to him by his parents when he was just a toddler, he has always had a bird’s eye for detail.  Growing up in Virginia, Colorado, and Maryland’s Eastern Shore, MacNeil found a home on the northern boundary of Yellowstone National Park.  MacNeil is a published writer, photographer and naturalist. His images have captured remarkable moments that were published in Rolling Stone Magazine, USA Today, Budget Travel, and numerous regional magazines to name but a few. He has been featured as an on-camera Park Ranger for a Discovery Channel documentary, and an on-camera Naturalist for Yellowstone DVD’s by Finley-Holiday Films.

MacNeil has delightfully educated university & college groups, families, Elderhostel groups’, and numerous private tours through single-day and multi-day excursions in Yellowstone.

MacNeil can be found driving the roads and walking the trails and thermal basin boardwalks, educating visitors about Yellowstone’s dynamic natural and cultural resources. When not guiding, MacNeil is enjoying some “Daddy Time” with his kind-hearted daughter and lovely wife, or roaming the hills (outside the Park) at random with his faithful dog!

Meet our Seasonal Naturalist Guides

Shauna Baron holds a B.S. in Biology, and a M.S. in Science Education. Shauna has been teaching outdoor education for over 20 years, sharing her love and knowledge of the outdoor world with students of all ages. Her biology research has led her to numerous parts of the United States to study the predator-prey relationships of large and small carnivores, such as wolves, bears, fishers, and bobcats. She was a volunteer biologist with the Yellowstone Wolf Project during the earliest days of wolf recovery. She also worked as a biologist for the U.S. Fish and Wildlife Service Red Wolf Recovery Program in North Carolina, and spent her free time working on research projects for brown pelicans, tundra swans and sea turtles. Next, she was studying scat for the University of Vermont; that’s right, she is not afraid of a little dirty work. Although her passion for the outdoors has taken her back and forth across the U.S. a few times, she always returns to Yellowstone Country. For the past 14 years, Shauna has been living on the Yellowstone park boundary, working as a naturalist-guide in Yellowstone National Park. Her multi-faceted programs provide an in-depth knowledge of the natural history, ecology, and geology, as well as the thermal biology of the “wonderland” we call Yellowstone. She is looking forward to sharing this amazing place with you.


Chelsea DeWeese

Chelsea Deweese holds a B.A. in environmental journalism from the University of Montana, Missoula. She has guided in the Greater Yellowstone Ecosystem since 2010. Chelsea’s love of Yellowstone began at a young age while growing up along the western shoreline of Yellowstone Lake. She would later move on to school in Gardiner, Montana, and then college where she reported on the economic impacts of wolf restoration to Yellowstone and its surrounding communities; fungal infections in Yellowstone’s Whitebark pines and how the blight affected attempted delisting of Yellowstone grizzly bears in 2005; and efforts to improve equitable access to national parks for underrepresented populations. Chelsea worked as a ski instructor and snow coach driver in Yellowstone before embarking on a five-year career as an environmental instructor with the Yellowstone Association Institute (later to become part of Yellowstone Forever). During summers, she guided multi-day river expeditions in Grand Canyon. Chelsea enjoys sharing Yellowstone with first-time and return visitors, finding quiet spaces to connect with nature while imparting the importance of staying involved to help protect this national treasure. Her writing can be found in various publications including Yellowstone Quarterly, Parks and Recreation,OM, Northern Arizona Mountain Living, and Rediscover Montana magazines as well as newspapers including the Wall Street Journal and Washington Post. She looks forward to helping you plan and create your most positive and memorable Yellowstone experience.

“May all your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view, where something strange and more beautiful and more full of wonder than your deepest dreams waits for you.”
