I've been to Yellowstone 3 times so far, and this National Park never stops to amaze me. It has so much to offer, and the nature is so fascinating. It is one of my favourite places in the world to visit. It has the world's largest concentration of geysers (more than 300 geyers, or two thirds of all those on the planet). There is wildlife in abundance such as grizzly bears, wolves, bison and wapitis.

The description of the UNESCO is:
"The Grand Canyon is among the earth’s greatest on-going geological spectacles. Its vastness is stunning, and the evidence it reveals about the earth’s history is invaluable". And all I can do is agree whole-heartedly! The grandness of the Canyon is mind-boggling and it just took my breath away. And on my second visit, it was even more impressing than the first. Seeing the sunrise slowly lighting up the Canyons walls on this September day in 2010 is one that I will never forget.

Redwood National and State Parks is covered with a magnificent forest of coastal redwood trees, the tallest and most impressive trees in the world. And impressive they are! It is hard to grasp how huge these trees are in reality. And although one instantly only thinks of the forest in these Parks, also the coastline itself is included. The marine and land life are equally remarkable, in particular the sea lions, the bald eagle and the endangered California brown pelican.

The beautiful Glacier-clad peaks, hiking through extensive alpine meadows, and being surrounded by an extensive old growth forest. Olympic National Park is among the best example of intact and protected temperate rainforest in the Pacific Northwest. On the western side of the park the 'rain'-forest embraced us in its full meaning, with everything in the forest covered by thick layers of moss.

'Impressive' is the word that comes to my mind when thinking back to my visit to Yosemity National Park. With its 'hanging' valleys, many waterfalls, cirque lakes, polished domes, moraines and U-shaped valleys, it provides an excellent overview of all kinds of granite relief fashioned by glaciation. My best memory is a very early morning, with the sun barely rising, filtering through a thin layer of morning mist, showing the surrounding landscape at its best.

The description of the UNESCO of the Everglades is: "The exceptional variety of its water habitats has made it a sanctuary for a large number of birds and reptiles, as well as for threatened species such as the manatee." I visited the Everglades many many years ago, and wish I had more time here, to take in more of the natural beauty of this National Park.

Last in the list, but absolutely not least: Waterton Glacier International Peace Park. I only visited once, but am always dreaming of returning to this park. Some of my favourite memories of visiting National Parks are from Glacier National Park. Both the landscape, the amazing hikes, as well as the abundance of wildlife, has made this one of my favourite places in the world.
