Maui is the second largest island of Hawaii but the most popular among tourists, for its 50 km of paradisiacal beaches, lush jungles and magnificent golf courses. A real beauty. The island is formed by two volcanoes joined by an isthmus and its main beaches are Red Sand (Kaihalulu), Hookipa, Big Beach and Little Beach (Oneloa and Pu'u Olai) and Black Rock (Kaanapali). Lao Valley State Park, Waianapanapa, Haleakala National Park and the Seven Sacred Pools are part of its natural attractions. At the Maui Ocean Center there are more than 60 fascinating exhibits and from its observation deck you can watch humpback whales.
