The Big Island, or Hawaii Island, is the largest Hawaiian island by land area, spanning over 4,000 square miles.

With a total area of nearly 4,000 square miles, the Big Island—officially known as Hawaii Island—is the largest in the Hawaiian archipelago. It is bigger than the entire group of Hawaiian Islands. The Big Island is well-known for its varied topography, which includes deserts, lush rainforests, black sand beaches, and active volcanoes like Kilauea and Mauna Loa. Because of its enormous size, it is a special place to learn about the geological and cultural history of Hawaii. Because of continuous volcanic activity, the island is expanding, gaining fresh land along its coasts. The Big Island is unique in Hawaii because of its size, diversity, and scenic beauty.
