In the heart of the western United States, specifically where Montana, Wyoming, and Idaho meet, lies Yellowstone National Park.

"Yellow stone? What a cute name!" you might think lightly, but this is a place where you can experience firsthand that the Earth is still alive and breathing with heat.

Yellowstone National Park is the first national park in the United States and one of the most famous in the world, established in 1872, and located at the junction of Wyoming, Montana, and Idaho.

This park boasts a massive area of 8,983.18㎢, which is about 14.84 times the area of Seoul. Just its size gives you an idea of how vast the natural world it encompasses is.

Yellowstone is even larger than South Korea's Chungcheongnam-do (8,247.2㎢), Chungcheongbuk-do (7,407.4㎢), or Jeonbuk Special Self-Governing Province (8,073.2㎢).

The name of Yellowstone National Park is derived from the yellow stones. Many rocks in this area appear yellow due to minerals containing sulfur.

These yellow rocks become a unique natural beauty and symbolic feature of the park, leaving a strong impression on visitors.

Yellowstone boasts a variety of natural landscapes, including mountains, plains, primeval forests, valleys, geysers, and hot springs, all of which play a significant role in making this area a world-class tourist destination.

Geysers and hot springs are representative natural phenomena here, with famous geysers like Old Faithful erupting huge amounts of hot water at regular intervals, leaving a deep impression on visitors.

Yellowstone is also famous as a habitat for various wildlife.

This place is a paradise for wildlife, home to many species such as gray wolves, grizzly bears, buffalo, elk, and white-tailed deer. The opportunity to observe these animals in their natural state offers tourists a very special experience.

In particular, during winter, there are many chances to witness the activities of grizzly bears and gray wolves.

Due to its outstanding natural value and historical significance, Yellowstone was designated a UNESCO World Heritage site in 1978.

This means it is recognized as one of the most important and beautiful natural heritages in the world, and it is one of the reasons millions of tourists visit here each year.

Activities you can enjoy in Yellowstone include hiking, camping, biking, fishing, and photography. The hiking trails are very well maintained, allowing you to walk along various difficulty levels of trails through mountainous terrain.

The scenery here is so beautiful that it cannot be expressed in words, and it is stunning from any angle. Additionally, in summer, you can enjoy boating or kayaking on the lakes within the national park, and in winter, many people enjoy snowshoeing or cross-country skiing.

Yellowstone is not just about boasting beautiful nature. It is one of the largest supervolcano regions on Earth, and the geothermal activity here is very active, providing important information for understanding the natural history of the planet. The geological characteristics of this area are also a significant subject of research for scientists, and its importance holds high scientific and educational value in many aspects.

Yellowstone National Park is more than just a "beautiful place"; it is an important site where you can directly experience the wonders of nature and the history of the Earth. Its scale, diversity, and the mysteries of nature will provide visitors with an unforgettable experience for a lifetime.

If you want to get close to nature, hear the rough breathing of bison instead of the noise of the city, and feel the 'hot heart' of the Earth... be sure to visit Yellowstone. As someone who has traveled around various places in the U.S., I highly recommend it.
