Big Island of Hawaii Helicopter Tours - The Kilauea Volcano on the Big Island has been in continuous eruption for over two decades and as such is one of the most dramatic and spectacular sites to be seen by any helicopter flight anywhere in the world. Helicopters flying over the rift zones generally can see the molten lava down in the core of the vents or flowing in rivers through tubes on their journey to the sea where they can be seen spewing clouds of steam and gas high into the air as the hot lava enters the ocean. Kilauea Volcano is closest to the city of Hilo so departing from there would be your least expensive option and flights are generally between 45 minutes to an hour long. If your staying on the Kona or Waikaloa side of the island you can also fly in a helicopter to see the volcanic activity but it is a much greater distance to traverse. Those tours, which also include a fly over of the beautiful Kohala forest reigon are usually about two hours in length and are priced accordingly higher. If you choose to drive from Kona to Hilo to take a flight you can expect a drive, one way, of approximately two and a half or three hours.
