Permit hikes afford trekkers the chance to explore the outdoors with fewer crowds. Not all trails are created equal, and there are those strictly protected to preserve their landscape, wildlife, and ecology. Permit hikes are essential in places deemed sacred, too. Securing permits is the first step to adventure, and the United States has some of the best trails for hikers who want to get out there.

Not anyone is patient in getting permits, but those who successfully do so will have the chance to commune with Mother Nature without the throng of people. Hiking, after all, is one of the best ways to appreciate nature’s grand show.

10 Havasu Falls

Tourists will have a slice of paradise in Havasu Falls; a landmark tucked in the Grand Canyon. This mesmerizing attraction is one of the most sought-after in Arizona – if not the world. It is located in the lands of the Havasupai people, so visiting it is highly regulated, as it should be, because its magnificence needs to be protected for future generations. It is recommended to visit from February to November, and a prior campground or lodge reservation is required. The overnight trip is always worthwhile when trekkers reach the mesmerizing falls.

9 Half Dome Cables Route

At 8,800 feet above sea level, Half Dome is one of Yosemite National Park’s iconic attractions. A report once said that it is “perfectly inaccessible,” yet George G. Anderson reached its summit in 1875, establishing the permanent route to “one of the prominent points about the Yosemite which never has been, and never will be, trodden by human foot.” Day hikers need to secure a permit via lottery before they can follow the footsteps of Anderson and declare, once atop, that they have conquered what the early people deemed impenetrable.

6 Kalalau Trail

When in Hawaii, tourists might as well go for a hike through Kalalau Trail on the island of Kauai.

It was once dubbed one of the most dangerous trails in the country but affords tourists unmatched panoramas.

5 Mt. Whitney Trail

Those up for a challenge when exploring California outdoors should head to Mount Whitney, the highest peak in the contiguous U.S. It has an elevation of 4,418 meters above sea level, and the trail reaches an elevation of over 1,800 m.
