Visitors must carry their own light source if planning to explore the lava tube in its dark, natural state before 10 a.m. or after 8 p.m. Park rangers recommend head lamps and flashlights; cell phones are not recommended as the only light source.
“When we turned the lights off to install the new electrical system, visitors told us they were in favor of leaving an option for a ‘lights out’ natural cave experience in Nāhuku,” said Park Superintendent Cindy Orlando. “We’re excited that the new lighting schedule satisfies visitors, is better for the environment, and supports our goal for a sustainable future,” she said.
The new lighting system also increases visitor safety by illuminating the interior, and protects the cultural integrity of the ‘ana (cave) by inhibiting the growth of non-native plant and algae species.

The native rainforest surrounding Nāhuku is home to endemic plant, bird and insect species, like the Happyface Spider. Visitation is heaviest between 10 a.m. and 2 p.m., and parking is limited to 30 minutes.
