About Maui

Maui's Road to Hana winds past waterfalls and rainforest to the island's remote east, while the Haleakalā crater rises above the clouds at sunrise. Lahaina and Kā'anapali handle the beaches and snorkelling, and humpbacks fill the channels from December to April. The island is warm year-round; spring and autumn are quieter, and winter brings the whales and north-shore surf.
