Haleakalā National Park, located on the island of Maui in Hawai‘i, showcases the dramatic landscapes of a volcano. Visitors can hike through the crater, explore lush rainforests in the Kīpahulu District, watch the sunrise, or stargaze under pristine night skies. Notably, the park is home to the endangered Hawaiian silversword plant and more endangered species than any other U.S. national park. Its name, meaning “House of the Sun,” stems from Hawaiian legend.
