Active-ism: Yellowstone and the Grand Tetons with Leah Thomas
Step into the awe-inspiring landscape of Yellowstone National Park on a purpose-driven adventure through one of the most ecologically and culturally significant places in the USA. Across the vibrant terraces of Mammoth Hot Springs and the powerful spray of Old Faithful, witness Yellowstone’s geothermal wonders and incredible wildlife – including bison, elk and perhaps even a glimpse of elusive wolves on a special tracking expedition.
Alongside the natural highlights, this trip dives into Yellowstone’s rich cultural and ecological significance, shining a light on its connection to the 27 Indigenous tribes who have long called this land home. Hosted by environmental author Leah Thomas, this journey offers the chance to connect with like-minded travelers, recharge in nature and turn awareness into meaningful action.

About the trip
This trip is part of our special Active-ism range, a series of adventures created for travelers who want to explore and help protect the USA’s national parks. The National Park Service is facing its largest ever budget cut, putting access, preservation and local communities that rely on tourism at risk.
We've partnered with Leah Thomas to give our Yellowstone & Grand Tetons Adventure trip an Active-ism twist, with the goal of helping travelers learn how to advocate for the parks' futures.

Welcome to Wyoming! Your adventure begins in the historic town of Jackson, where fur trappers and frontiersmen once gathered. Surrounded by towering mountain ranges, Jackson is your gateway to discovering Yellowstone National Park. Explore the town’s nightlife, walk the plaza or maybe head to the famous Million Dollar Cowboy Bar for a drink with your new fellow travelers.
Embark on a day of exploring Grand Teton National Park, one of the most stunning places in Wyoming. Perhaps take an optional boat trip across Jenny Lake, hike to Inspiration Point, or have a picnic and enjoy the serenity. Visit the Mormon Row Historic District to see the iconic Moulton Barn with the Tetons towering behind while scouting for buffalo and antelope herds.
Visit Yellowstone National Park, the crown jewel of the American national parks. You’ll explore the southern loop today and watch Old Faithful Geyser spray before being hypnotised by the colours of the Grand Prismatic Spring. You have three full days to fully immerse yourself in this unique landscape.
Spend the day exploring the northern loop of the park, which includes the Grand Canyon of the Yellowstone, an icon of the park’s complex and dramatic geological history, and the Norris Geyser Basin, the hottest and oldest geyser in Yellowstone’s thermal areas. Along the way, look out for abundant wildlife, including birds and grazing elk.
Today, you’ll join a naturalist guide on a wolf-tracking adventure in the park. High-power binoculars will be provided during the tour, so you have the best shot at glimpsing the wolves, as well as lots of other wildlife like bison, elk and bears. While you’re searching, your guide will share more about conservation efforts in the park.
This morning after breakfast, take a scenic drive back to Jackson. Watch the Idaho scenery pass you by as you follow the western edge of the Tetons and then cross the Snake River in Wyoming. You’ll arrive in Jackson at about 3 pm this afternoon, where your trip will come to an end.
