Get metaphorically lost in the immense grandeur of Grand Teton and Yellowstone National Park on this seven-day adventure. Using your own two feet (and the occasional boat), awaken your inner explorer as you encounter spectacular canyons, lush forests, serene alpine lakes, hot springs, and dramatic geysers. Don’t get too mesmerized though, you’ll need to be sharp in order to spot the bears, wolves, bison, and elk that roam these storied parks.
