2 . The State of Colorado has four of the best parks out of the 58 national parks in the United States. The parks have some of the best scenery of all the national parks.

Black Canyon (峡谷) of Gunnison National Park

This park offers the most breathtaking views from up in the mountains into the canyons below. While exploring the canyons, you will find that the walls drop nearly straight down into the narrow valleys of the snake-like rivers below. Visitors are offered more than 100 camping sites, and a lot of bird species and many animals are native to the area.

Rocky Mountain National Park

It is the only national park in the north central region in the state of Colorado. Elevations in this park are anywhere from 8,000 feet to 14,259 feet at the top of Longs Peak. While traveling throughout this park you will notice two very different climates because of the difference the upper peaks of the Rocky Mountains make. You can enjoy 359 miles of hiking trails, a lot of places for camping, horse-back riding and beautiful scenery.

Mesa Verde National Park

This is probably the most interesting national park, offering a fascinating trip back in time to 600 AD up to 1300 AD．This park was declared a protected national park in 1906 because of the cliff dwellings(住所) that were found throughout the area, which were once home to American Indians. Many of these dwellings can be walked through, while you imagine what each room may have been used for so many years ago.

Great Sand Dunes (沙丘) National Park

The Great Sand Dunes National Park lies in south central Colorado, about 127 miles from Pueblo. This park has the tallest sand dunes in all of North America and has trails for hiking. The natural sandy beaches around the small rivers and lakes are good for swimmers.
