Yellowstone Lower Loop Full-Day: The Volcano, Old Faithful & Grand Prismatic
Select participants and date
The bus hums awake before dawn in West Yellowstone, headlights cutting through a blue-gray chill as steam rises from the river like a live thing. By the time you cross the park boundary the world has already changed: pine-smelling air, prismatic steam plumes, and a driver-guide whose voice is both map and story. For the next seven to eight hours you ride the lower loop of Yellowstone, moving from thunderous falls to the delicate colors of geothermal pools, while the landscape seems to rearrange itself every time you round a bend.

Adventure Tips
Layer for rapid temperature swings
Mornings near thermal basins are chilly but sun can warm mid-day fast; pack a light insulating layer and a wind shell.
Stay on boardwalks
Thermal ground contains arsenic and silica; never step off designated paths and keep pets off the boardwalks for their safety.
Bring a small daypack
Even though snacks and water are provided, carry sunglasses, sunscreen, and extra water for longer walks and photo stops.
Follow guide instructions for wildlife viewing
Use provided spotting scopes and maintain distance—do not approach animals even if they appear calm.
