It is not just the world-famous beaches that make Maui one of Hawaii's most popular vacation destinations. Known as "The Valley Isle" because of the lush rainforests that grow between its two large dormant volcanoes, the entire island is an area of outstanding natural beauty. Travel the eastern coast and you'll see the deep-blue waters of the Pacific, tropical jungles and sparkling waterfalls. And that's before you reach Haleakala, the massive crater-topped national park with its magical moonscapes and mythical sunrises and sunsets. In fact, it can be a challenge to turn your head on this 727-square mile island without seeing some kind of camera-ready natural feature—a stark cinder cone, a secret cove, a grassy plain. Just set a little time aside to visit those beaches.
