3-Day Yellowstone & Grand Teton Upper & Lower Loop Wildlife Tours

Mammoth Hot Springs and Lamar Valley are two of the Upper Loop’s most unforgettable highlights. At Mammoth, travertine terraces glisten like frozen waterfalls, shaped over millennia by shifting hot springs—a living testament to Yellowstone’s volcanic heart. Elk often wander near the village, showing how wild and human spaces coexist. Lamar Valley, carved by ancient glaciers, is a haven for wildlife. Herds of bison and pronghorn graze the meadows, while wolves and bears roam, creating an untamed scene. The Upper Loop also features Tower Fall, steaming Calcite Springs, and the ancient Petrified Tree, each revealing Yellowstone’s dramatic past. Pair this with the Lower Loop’s geothermal wonders, such as Old Faithful and Yellowstone Lake, or the alpine beauty of Grand Teton National Park, featuring jagged peaks, clear lakes, and abundant wildlife, for an unforgettable Rocky Mountain experience.
