Today, view some of North America's most spectacular mountain scenery - and keep an eye peeled for wildlife ranging from moose and elk to beavers and bald eagles - during a ten-mile float trip* along the Snake River in Grand Teton National Park; there's no better vantage point than your raft on the river from which to gape at (or photograph) the majestic peaks of the Tetons. Then pay a brief visit to the park's Mormon Row Historic District, whose preservation is being supported by a major grant from Tauck. A homesteaders' settlement dating back to 1890 located in an undeveloped area of the park, Mormon Row is home to a number of weathered historic structures - including the iconic T.A. Moulton barn, an unofficial symbol of the park - that (along with their dramatic Teton Range backdrop) attract photographers from around the world, and convey the sense that you've traveled back in time. Continue on to the historic and trendy Western town of Jackson, gateway to the Tetons and the Jackson Hole region, for an afternoon spent as you please. Enjoy dinner at your inside-the-park lodge tonight.

With 10,000 hot springs, thundering waterfalls, two-thirds of all geysers in the world and endless forests, Yellowstone inspires awe. Explore its geologic wonders - including hundreds of geysers, brilliantly colored hot springs, steaming fumaroles and more - that early 19th-century skeptics found too astounding to be believed as you follow the Lower Grand Loop Road to Fountain Paint Pot's collection of colorful, bubbling mud pots. Then view the dramatic Grand Canyon of the Yellowstone, carved by the churning waters of the Yellowstone River. Make your way through Hayden Valley before arriving for an overnight at Mammoth Hot Springs Hotel and Cabins, where you'll settle in and have dinner this evening.

Upon departing Cody this morning, traverse the Bighorn Mountains with their breathtaking vistas of rugged canyons, sparkling waterfalls, miles of grassland, and colorful vegetation en route to a double dose of authentic Wyoming ranch life. First, feel the spirit of the West during an authentic ranch experience - including a cookhouse lunch, then your choice of a horseback ride*, a horse whisperer or a roping demonstration - at the TA Guest Ranch in Buffalo, Wyoming. Set in the heart of cowboy country, TA Ranch was the site of a famous siege and shootout during the infamous Johnson County War in 1892; you can still see the old gunshot holes in the ranch's original horse barn. Later, continue on to an overnight and dinner at your leisure at a different Wyoming ranch, the Ranch at Ucross.
