Na Pali Coast, Kauai
Stretching across more than 27 kilometers of Kauai's northern shore, the Na Pali Coastis the island's most famous juncture with the ocean. The occasional waterfall adds to the already dazzling beauty of these jagged green cliffs. You can experience the Na Pali Coast from the Kalalau Trail, but this hike isn't for the faint of heart. You can also see the coast by boat or enjoy views on the cliffs from the eastern end of Route 560, about 17 kilometers west of the resort town of Princeville.
Waimoku Falls, Maui
The short hike to Waimoku Falls - located in the southeastern part of Maui's Haleakala National Park - is a worthwhile detour along the island's famous Road to Hana Drive. One can follow the Pipiwai Trail through several bamboo groves and they will find themselves staring up at the 122-meter-high falls.
Hawaii Volcanoes National Park, Big Island

Molokini, MauiA less fiery view of Hawaii's volcanic history can be found at Molokinki, a half-moon-shaped islet found about four kilometers off the southwest coast of Maui, making it an easy day trip from Maui's resorts. Molokini is all that remains of a violent volcanic eruption that rocked the Pacific around 230,000 years ago.
Waimea Canyon, Kauai
Although it's not nearly as large as its Arizona counterpart, the 'Grand Canyon of the Pacific' boasts some memorable scenery. Numerous lookout points offer panoramic views of the 22.5-kilometer-long, 1,100-meter-deep canyon on the northwest side of Kauai. One can also follow Waimea Canyon Drive, which cuts through the state park and leads down into the canyon, weaving between the rusty buttes. One can also take a helicopter ride here.
