Years ago I participated in a panel discussion regarding travel and the Internet. At one point in the discussion each panel member was asked what he or she considered to be the best travel bye on the Internet. My response was that for me, the best travel buy is when you find that very special place to stay or have dinner or special thing to see or do that you will always remember as a highlight of your trip.
Over ten years ago, I came across the website for the Mauna Kea Summit Adventures. Their site impressed me and their tour tours seemed even more interesting. When my wife and I visited the Big Island soon thereafter, we made sure to book one of their trips.
Mauna Kea Summit Adventures offers you the opportunity to view the Hawaiian islands from the peak of the tallest mountain in the world, if measured from the bottom of the ocean. You then view the sunset and later have a chance to view the heavens with more clarity than you have ever seen in your life.
