While the National Parks of the United States are natural treasures, they’re also very popular tourist destinations, attracting millions of people every year.

Covering millions of acres throughout the country, there’s a total of 58 protected areas known as national parks. Some are more famous than others, but all of them have their own special and unique attractions, making them some of the most truly amazing places on earth.

  1. There are time when these places are completely empty and you wouldn’t expect it. WhatsBusy.com forecasts foot traffic for the national parks and monuments. They launch March 1 2013

  2. Great Smokey, only because it’s closer to large populations tha any of the others. I vote Zion number one for beauty, followed by Yellowstone for it’s vast size and unique geology and Cater Lake for it’s singularity.
