The Hawaiian islands are known for their incredible natural beauty, with idyllic beaches, towering volcanic craters and cliffs, tumbling waterfalls, and lush rainforest.
In Kauai, the legendary Na Pali Coast is a huge draw. The na pali, or "many cliffs," can only be visited by air, by sea, or by hiking the Kalalau Trail.
The Waimea Canyon, on Kauai's west side, is known as the "Grand Canyon of the Pacific." You can view the canyon from roadside lookouts, hike in the state park, or soar over the canyon on a helicopter trip.
On the Big Island, you may be lucky enough to visit when Kilauea (in Hawaii Volcanoes National Park) is erupting. The park also features scenic drives, lava tubes, and crater hikes.
Punalu'u Black Sand Beach, on the southern tip of the Big Island, is not only gorgeous, it's also a place where you may see Hawaiian green sea turtles.
In Maui, the Haleakala crater towers over the island. You can drive up to the summit for sunrise or sunset, and hike the Sliding Sands Trail into the heart of the crater.
Hiking Diamond Head is one of the best things to do in Oahu. From the top of the crater, you have sensational views over Waikiki and the southeast coast of the island!
