We LOVED this experience and will never forget it. We were picked up in HIlo by Addison, who was our driver and tour guide. He was terrific. Personable and knowledgeable. Mauna Kea is simply stunning and awe-inspiring. And to watch the sun set from the summit was something I will never forget. The tour provides warm parkas and gloves, with hot drinks and snacks after, but I sugest wearing warm clothes as it was windy and in the low 40's when we were there. The star-gazing part was nice, but the real reason you do this tour is the summit and that was what this is all about. Highly recommend!!!
