I liked the smaller helicopters because one can zoom around like a sports car. Also, each side can have doors off, so opportunity for great pictures and actually feel the heat from the volcanos. We went to several Viatar excursions this trip and the helicopter ride was definitely the best.
This was an amazing trip! The pilot flew us over Kīlauea and to areas of active lava flow, which made for great pictures! He also took us down to where the lava met the ocean. He told us about the volcano and the many eruptions that have occurred. He was very knowledgeable. Next, he took us to fly over the Rainbow Falls, which was really pretty. In all locations, the pilot made sure that both sides of the helicopter got to see the sites. The only caution I would give is, if you get air sick, make sure you let the pilot know. The corkscrew turns to get pictures of the sites can make you pretty sick. But I wouldn't let that stop you from taking the trip!
Great tour and easy to find the helicopter check in at the airport.
