About Nahuku - Thurston Lava Tube
Nahuku, also known as the Thurston Lava Tube, is a fascinating natural wonder located in Hawai‘i Volcanoes National Park on the Big Island of Hawaii. This lava tube was formed over 500 years ago when a river of molten lava flowed beneath the surface, eventually cooling and solidifying on the outside while the hot lava inside continued to drain, leaving behind a hollow tunnel.
The tube stretches approximately 600 feet and is an easily accessible attraction, offering visitors a unique opportunity to walk through a subterranean volcanic passage. The pathway is well-lit, showcasing the smooth, curving walls and ceiling formed by ancient lava flows. Surrounding the entrance is a lush rainforest filled with towering ferns and native Hawaiian plants, creating a striking contrast between the vibrant greenery and the dark, cavernous tunnel.
Nahuku is named after Lorrin Thurston, a newspaper publisher and early advocate for the national park, who helped bring attention to this geological marvel. Visiting the lava tube provides a glimpse into the island’s volcanic past and the powerful forces that have shaped its landscape. A walk through Nahuku is both an educational and awe-inspiring experience, making it a must-visit destination for nature and adventure enthusiasts.
