Select participants and date
Before dawn the road out of Gardiner yawns open and the bus eases into the cool pulse of Yellowstone’s Upper Loop. Headlights pick out pockets of steam rising from thermal basins, and on a clear morning bison silhouettes drift like slow ghosts across Lamar Valley. On this full-day loop—Lamar, Mammoth, Norris, and the Grand Canyon—the landscape moves with its own timetable: geysers that count in minutes, rivers that carve in millennia, and animals that decide when to appear.

Adventure Tips
Start early for wildlife
Predators and most wildlife are most active just after sunrise—arrive on time and be prepared to wait quietly at pullouts.
Wear sturdy, waterproof layers
Weather can change rapidly on the loop; a lightweight waterproof shell and insulating mid-layer will keep you comfortable through wind or brief snow.
Stay on boardwalks in thermal areas
Thermal features are fragile and dangerous—never leave designated paths to get a closer photo.
Bring snacks and water
Although lunch is provided, carry extra water and quick snacks for wildlife stakeouts and time on the road.
