We went with blue Hawaiian helicopters and we were absolutely blown away. We couldn’t have picked a better day to go; our tour guide was hilarious (Brian) and we were lucky enough to get the front seats. Since the weather was so great and there was barely a cloud in the sky, we had the chance to go right into the crater. I’m not a religious person but that experience was holy. I nearly cried it was so breathtakingly beautiful. HIGHLY HIGHLY recommend! I couldn’t believe you could see the whole island in an hour, but we really did. A must do while in Kauai
