Puna

Puna is the farthest east town in Hawaii. Apparently, scientists test "virgin" air there because it's been floating over nothing but ocean for thousands of miles. Smelled good.

Puna is a very cool town, and the weather finally broke the day we explored there. This is a natural steam room, created by volcanically heated steam that rises into caves like this one. It was not quite as warm as a sauna here, but very warm and steamy. This one even had benches put in there by locals.

We also got to swim in a natural freshwater swimming pool 40 feet from the ocean and saw a series of tide pools created by lava flows. You get to see things in Hawaii that you see no where else on the planet.
