Kalalau Valley, Hawaii

Hawaii is not only known for its world-class surf and beaches with snow-white sand; this tiny archipelago is also a mountainous natural paradise. Since a large portion of the island of Kauai is covered in rainforest, it is referred to as the "Garden Isle." On Hawaii's Kaua'i Island, Kalalau Valley is regarded as the island's cathedral and is tucked away along the N Pali Coast. It is arguably one of the planet's greatest natural wonders and features a secluded beach encircled by towering peaks.

The valley has been valued for its beauty almost since its inception, as a historically highly populated place with a large thriving community living there until the twentieth century, after which only those with permits were allowed to occupy the "unspoiled" land. With a 90-day pass, one can see the esteemed valley if they are prepared to show some athleticism by trekking a few days-worth 11-mile hike inclusive of camping overnight(s) from Ke'e Beach.

The most rewarding way to get there is probably by hiking the Kalalau Trail, where you'll first see its steep, flower-covered cliffs that seem to be ridged like draped cloth as they descend to the royal-blue ocean. The beachfront Hanalei Colony Resort is close to some of the island's top snorkeling locations and the Kalalau Trail.

Hiking two miles to Hanakapi'ai Beach, where one must cross the Hanakapi'ai Stream, which is known for causing flash floods due to rapidly rising waters. The "Crawler's Ledge," a mountain-embracing narrow footpath that drops steeply off into a vast chasm with the tumultuous sea, begins at mile seven. Only those with cat-like grace and instincts who want to commune with nature, self-reflect, and unwind from the city should set out in good weather. Wandering through hidden paths in the rainforest, relaxing by the ocean, and sleeping under the stars make for an unforgettable trip. Everyone else can take a tour by boat or helicopter.
