Yellowstone National Park

Yellowstone National Park is America's first national park. It was established in 1872. Yellowstone extends through Wyoming, Montana, and Idaho.  The park's name is derived from the Yellowstone River, which runs through the park. It's unclear if the name first referred to the sulfurous yellow rocks below the falls of the Grand Canyon of the Yellowstone River or to the sandstone bluffs that border its shores.

Within the massive park boundaries, you can find mountains, rivers, lakes, and some of the most concentrated geothermal activity in the world. The park has 60% of the world’s geysers as well as many hot springs and several mud pots. Perhaps the most famous feature of the park is the geyser Old Faithful.

You can also see the Grand Canyon of the Yellowstone River, one of the world’s largest petrified forests, and countless waterfalls. The park is also home to diverse wildlife, including grizzly bears, wolves, bison, and elk.

Outdoor recreation is boundless in this iconic national park. Madison and Yellowstone River are stocked with brown and rainbow trout and mountain whitefish. The many bike trails include an abandoned railroad bed that winds along with the wild Yellowstone River. You can backcountry camp or hike on the extensive trail system throughout the entire park, or boat on Yellowstone Lake. Stock outfitters lead horse and llama trips into the backcountry.

Historic points of interest include Fort Yellowstone, the permanent post of the cavalry when they managed the park in the late 19th century before the National Park Service was established in 1916. Old Faithful Inn is one of the last log hotels in the United States and is an impressive seven-story building of beautiful rustic architecture.

The original American national park and an icon of the entire National Park System, Yellowstone National Park is an American gem with millions of park visitors each year. Because of its magnitude and diversity, it is a park that really requires several visits to appreciate all it has to offer. Created in 1872 as the first national park in America, it set the standard for the entire national park system and is for many the most iconic park in the country.

I was surprised at the number of geysers and hot springs. We were there 2 weeks ago and a wonderful time. Tried the bison at Mammoth Spring and it was fantastic. We stayed at Mammoth Springs and Old Faithful. They were some of the cleanest rooms I ever stayed in. The whole park was clean, even the port-a-pots.

just reading through some of these comments. This is for Holly B. Yellowstone is the 1st NATIONAL Park in the US, not a state park. I have visited Yellowstone a number of times and each time see something new and more breathtaking.

The comment on not being the oldest state park doesn't quite work because Yellowstone is a National Park, not a state park. Yosemite is the oldest nationally protected area. Lincoln signed the Yosemite Grant during the Civil War to protect the Valley and Sequoia groves. Yellowstone became the first official National park, followed later by the larger Yosemite National Park that encompassed the current boundaries.

I visited this park about a week ago and I can honestly say it was a pretty awesome experience. I'm just a 16 year old who lives in a small town named Greenfield in California, but where I'm from compared to this National Park this Park was the BEST!! THANK YOU!

You are wrong about this being the oldest State park i have been doing research and have found that Indian Springs State Park was obtained by the state of Georgia in 1825. My source http://outdoornation.org/profiles/blogs/americas-first-state-parks I have been to this park many times. Small but lovely it also has a natural spring that is open to the public to gather water from it. It has some of the best flavor and being all natural is good for you. (you should leave the containers open and covered with a screen until the sulfur smell has faded away for best flavor.) It may be a very small State Park but it is older than Yellowstone from the research I have done on this State Park. Also the park officials have allowed the Native American Peoples to keep a beloved tradition of having a true powwow each year in mid-September.

This was my first trip to YNP. I got to share it with my one and only and my parents. It was the best vacation I have ever had. The sights are wonderful and Old faithful was a dream. We spent three days wondering the park looking at the mud pots, petrified tree, wildlife and many waterfalls. On the last day as we were leaving the park God prvided my favorite animal for us to see, the almighty grizzly bear. Our United States of America is beautiful and I thank Him everyday for making it for us to enjoy.

Two weeks without TV. Two weeks without internet. Two weeks with minimal cell phone coverage. Two weeks without billboards and other ugly landscape clutter. Roosevelt and all the others were right in conserving the authentic views of the wilderness, valleys and mountains for all of us. We cannot thank them enough for pushing the National Park system.
