The Big Island Volcano Tours are the most popular tour in our roster, and our tour groups are less than 24 passengers for a more personal experience. Hope that helps!

Stay away from "Lava Boat Tours" as the owners will tell you the seas are great, when in fact on the north shore they can be huge for small boats. No Aloha spirit there brudda!
Much better choice is to take Blue Hawaii Helicopter tours. They are the safest and you will never see an active volcano like this from any other view point. Well worth the price!! about 7 years ago
