As the sun rises over the Rocky Mountains, the sounds of bellowing elk, croaking sandhill cranes, and howling wolves resonate across the valley. Alone in the fragrant sagebrush meadows, you encounter a herd of mother elk and newborn calves grazing in the cool morning air. On the hillsides above, you focus your spotting scope on a pair of courting black bears in the fresh alpine wildflowers at the edge of a montane glacier. Nearby, steam rises from the edge of a simmering hot spring as a great gray owl hunts in the nearby meadow. Bison and grizzly tracks skirt the orange and turquoise rim of the bubbling pool. On this week-long, small group safari into the heart of the wild, find out why the 18-million-acre Greater Yellow Ecosystem has been hailed as "America's Serengeti," "The World's Wonderland," and "the Land of Fire and Ice.”  (SOLD OUT)
