The USA's oldest national park, Yellowstone, is 145 years old this year. As a testimony to the kind of protection that national park status brings, Yellowstone remains one of the best wildlife habitats in the country. Not only are there both grizzly and black bears, here you can also find wolves, bison, elk, moose, several species of deer, mountain goats and mountain lions.
Here are the 12 oldest national parks in the USA, all of which existed before the National Parks Service was formed in 1916.
1) Yellowstone: 1 March 1872
Straddling Wyoming, Montana and Idaho, Yellowstone was the first National Park in the USA. It was, created by an Act of Congress signed by President Grant, after there had been plans to put the land up in a public auction. As well as its wildlife and jaw-dropping scenery, it's most famous for its geysers, most notably Old Faithful.

2) Sequoia: 25 September 1890
Also in the Sierra Nevada mountains in California, Sequoia National Park is where you'll find the Giant Forest. This contains five of the ten largest trees on the planet, including the General Sherman tree, a giant sequoia which is the biggest tree in the world and estimated to be at least 2,300 years old.
