Hawai‘i Volcanoes National Park protects some of the most unique geological, biological, and cultural landscapes in the world. Extending from sea level to 13,677 feet, the park encompasses the summits of two of the world's most active volcanoes—Kīlauea and Mauna Loa. From wilderness adventures to short walks and scenic drives, there's plenty to do in Hawai‘i Volcanoes National Park. Walk through lush rainforest and see a cave where a river of lava flowed 500 years ago at Thurston Lava Tube, or enjoy one of the many trails in the park, such as the Kīlauea Iki trail which descends 400 feet through rainforest into a volcanic crater, and hike across a hardened lava lake from the 1959 eruption. Check with the park regarding the latest activity at the crater.
