It is suggested that visitors allow three days to a week for a proper experience in Yellowstone National Park. There are hundreds of sites, kinds of flora and animals to see, but the ten spots in the park that you should not miss are:
Old Faithful/Upper Geyser Basin - Yellowstone is renowned for its hundreds of active geysers, the largest of which is Old Faithful, named for its predictability: it erupts for about four minutes every 60-90 minutes. The Upper Geyser Basin where Old Faithful is located has numerous geothermal features, including hot springs, mudholes and fumaroles.
Grand Canyon of the Yellowstone - Not to be confused with the Grand Canyon, this is a canyon of the Yellowstone River that descends to a depth of 900 ft/275 m and is a half mile/0.8 km wide.
Hayden Valley - Centrally located in Yellowstone, this is home to a large concentration of wildlife and fowl. Here you can see bison, elk, the occasional grizzly bear, ducks, geese, pelicans and spectacular views of the valley floor.

Mammoth Hot Springs - a complex of hot springs, located in the park's northwest corner, in the Mammoth District. Accessible year-round, with comparatively mild winters, it's the site of the park's main headquarters, Fort Yellowstone.
Yellowstone Lake - the largest high-altitude lake in the mainland 48 states; one can see ocean-like waves breaking against the shore on windy days.
Norris Geyser Basin - Echinus and Steamboat (the world's tallest geyser) are both located here. There are several miles of boardwalks from which you can see magnificent thermal features, elk and bison.
Lamar Valley - Located in the northeast section of the park, this is where the highest concentration of grizzlies can be found in the park. It's also home to elk, bison, osprey, bald eagles, antelope, moose and black bears.
Tower Fall - Located behind the General Store, this is one of Yellowstone's most popular waterfalls. It's recommended to take the short but steep hike down to the base of the waterfall. In the winter, it is accessible by following Roosevelt Junction to Tower Fall Road. Wear snowshoes or cross-country skis.
Fountain Paint Pots/Lower Geyser Basin - The multi-colored mud pots are located between the Lower and Midway Geyser Basins.
West Thumb Geyser Basin - This caldera within a caldera is the largest geyser basin on the shores of Yellowstone Lake.
