National Parks & Monuments Yellowstone and Grand Teton National Parks and Devils Tower National Monument showcase some of Wyoming’s most beloved natural treasures — from steamy geysers and jagged peaks to ethereal geologic wonders. More than 3 million people make their way to the world’s first National Park annually — and it’s easy to understand why. Home to the world’s largest concentration of geothermal features (more than 10,000 in total), North America’s largest high-elevation lake and hundreds of species of wildlife, the 8,991-square-kilometre park is a dazzling attraction. SPECIAL MOMENTS • Volcanism fuels the park’s wealth of geysers, boiling pools and bubbling mud pots — a result of the active mammoth magma chamber underneath the area. View more than 150 geysers, hot springs and fumaroles (openings in the earth’s crust that emit steam and other gases), including the famous Old Faithful geyser, in the Upper Geyser Basin. • Admire the largest hot spring in the U.S.: the Grand Prismatic Spring, a tie-dyed beauty that credits its brilliant colours to thriving microscopic colonies of pigmented bacteria. • At 94 metres, the Lower Falls at Grand Canyon of the Yellowstone is the tallest waterfall in the park. See and hear the thundering waters from several viewing areas, including Lookout, Red Rock and Artist Point. • Wildlife viewing is a must at the national park, a habitat for more than 300 species of birds, bears, bald eagles, grey wolves, elk and more. Spot the world’s largest herd of free-roaming bison in verdant Hayden Valley. For your safety, please stay at least 20 metres away from bison and at least 90 metres away from bears and wolves. 2 Wyoming Adventure Guide THE GREAT FOUNTAIN GEYSER AT YELLOWSTONE NATIONAL PARK, ISTOCK.
