We will be touring the Islands in April and was looking for some feed back on Helicopter tours. Have read a few posts about Kauai tour being the highlight of many trips. I'm trying to decide between Kauai and the Big Island, for our helicopter tour. We can do the land tour to Volcano National Park. The best rate is to book on line in advance but I am hesitant with the Big Island tour over the Volcano because of the weather. If it is cloudy or overcast we may only see steam. I have recently read about Vog in the alir also, which could affect this tour. Can anyone reccommend a carrier or shine some light on this subject. Don't do heights very good so chances are I will do one tour only!!Thanks.
