Boulder, CO -- While millions of visitors travel through the nation's national parks every year, few of these outdoor enthusiasts experience the true beauty and grandeur of these areas like guests on The World Outdoors' Yellowstone/Grand Teton and Glacier/Waterton hiking and multi-sport adventures.

The pristine wilderness and rugged beauty of America's most beloved national parks—Grand Teton and Yellowstone—set the stage for the company's action-packed Grand Teton/Yellowstone multi-sport offering. In six extraordinary days, guests discover waterfalls, buffalo herds, and thundering geysers while biking back roads and rafting renowned rapids.

Day one begins pedaling through Bridger-Teton National Forest with a gradual descent through beautiful alpine meadows to the Buffalo River valley. A walk through the Upper Geyser Basin, a visit to Old Faithful, and then a night spent in historic Old Faithful Inn make this day memorable. The following days are equally as sweet, with hikes that include breathtaking, panoramic views of snow-capped peaks, serene mountain lakes, and the golden-hued rim of Yellowstone's Grand Canyon; exploration of geothermal features and underwater geysers by sea kayak; hiking, biking, horseback riding, or fishing in Grand Teton; and a final afternoon of whitewater fun on the Snake River.

The Yellowstone Hiker trip makes the most of every moment in the country's finest national park. Tracing tranquil footpaths, participants hike and ride horseback as they explore a pristine wilderness of waterfall-filled canyons, rugged peaks, steaming fumaroles, spewing geysers, and hidden hot springs. Guests also witness the wonders of nature as they view bison, elk, moose, and eagles in one of the world's foremost wildlife sanctuaries.

The company's Glacier-Waterton multi-sport offering features hiking, biking, and rafting. The magnificent park lands of Montana's Glacier and Alberta's Waterton National Parks offer some of the most dramatic mountain scenery on earth. Guests immerse themselves in this mountain wilderness that is still wild with moose, bear, and bighorn sheep as they hike amid jagged, glacier-carved peaks and through sweet-smelling valley floors blanketed with wildflowers; bike over the Continental Divide by azure lakes; and raft the thrilling Flathead River on this diverse, action-packed trip.

The Glacier-Waterton Hiker adventure sends the senses soaring and spirits flying. With more than 800 miles of footpaths, Glacier National Park is one of the world's premier hiking destinations and is especially well suited for discovery on foot.
