Top 10 Natural Landmarks and National Parks In the United States America may be known for its man made landmarks, but there are a handful of natural landmarks that are really cool and underrated. In all honesty, I would really recommend going to visit these places if you have not. These are bucket list places and there’s more that are worth a trip as well. The Top Ten Grand Canyon Grand Canyon National Park, in Arizona, is home to much of the immense Grand Canyon, with its layered bands of red rock revealing millions of years of geological history. Located north of Phoenix in Arizona the Grand Canyon is a sight to behold, this great chasm measures one mile deep, 18 miles wide, and stretches for approximately 277 river miles. In all, the Grand Canyon National Park covers 1,218,375 acres. It’s one of the most iconic landmarks not only in the US but in the entire world. There’s multiple ways to see the Grand Canyon including the Skywalk, which is an extended see-through walkway built and maintained by the Hualapai Nation, a native group living in this region. Grand Canyon West and the Skywalk are not a part of the Grand Canyon National Park, but nevertheless, provide a stunning view of the area. The National Park itself contains the North and South Rim and offers hiking paths. On average about 5 million people visit per year
