Namakanipaio Campground
The main drive-up campground in Hawaii Volcanoes National Park, set in a grove of tall eucalyptus and ohia at around 4,000 feet. Staying inside the park is the whole point: you can drive out to the Kilauea overlooks after dark to see any active glow without a two-hour round trip from Hilo or Kona, and be back at the tent in fifteen minutes. A small number of simple cabins have historically been available alongside the tent sites. It is genuinely cold at night by Hawaii standards, and rain is common.
