For Letter Y, my choice is Yellowstone National Park
Yellowstone National Park
It’s considered to be the first national park in the world, located in the US states of Wyoming, Montana, and Idaho
The park is known for its many geothermal features, especially the Old Faithful geyser, one of its most popular attractions.
The first time I visited the USA, I stayed with my younger brother and his family in Idaho.
As a treat for me, they planned a three-day trip to Yellowstone Park. It was a wonderful experience. I took lots of pictures, trekked the trails, and enjoyed the sights. We stayed two nights in the motels which dot the different locations in the park. I still have my stuffed Bison and black bear which I bought from the souvenir shop.

It was a marvelous trip. Highly recommend visiting there if you’re nearby.
