Yellowstone National Park is a famous national park located in northwest Wyoming. It is very popular with tourists, receiving thousands of visitors each year. The natural sights like geysers are spectacular, and there is also a canyon, lake, and waterfalls. Brown bears live in the park and attract tourists. The park is open all year but some smaller facilities close in winter when it is cold and snowy. June and October are recommended times to visit as the weather is good and fewer tourists are present.
