Your curiosity has led you from coast to coast in search of Mother Nature’s most impressive stretches of land and sea. Have you crossed these three natural wonders off your bucket list?

The Grand Canyon

Grand Canyon, Arizona

Take in millions of years of stunning geological history at Grand Canyon National Park, home to one of the world’s largest canyons and arguably the most iconic landscape in America. The South Rim is the most accessible section year-round, and you can hike around the edge or even descend into the canyon itself. Plus, take your sightseeing experience up a notch with helicopter or river rafting tours.

Great Smoky Mountains

Sevierville, Tennessee

Witness the majesty of Great Smoky Mountains National Park, the most visited national park in the U.S. Explore the unbroken chain of mountains that run the span of the park, the highest of which is Clingmans Dome at 6,643 feet. Meander through wildflower fields, forests, and waterfalls all while trying to catch a distant glimpse of the symbol of the Smokies, the American black bear. Be sure to wake up early at least once to see the namesake low-hanging fog.

Nāpali Coast

Kauai, Hawaii

Untamed paradise awaits along this rugged stretch of gorgeous coastline. Nāpali Coast State Park is known for its towering sea cliffs, cascading waterfalls, and isolated beaches — all covered in lush greenery. Traverse 2 miles to pristine Hanakapi’ai Beach, the most popular day hike. Sail the coast aboard a charter boat with stops to snorkel along the way. Or, opt to see sweeping views from above on a helicopter tour.
