It was good stargazing (the best view of sirius and the moon I've ever had), and our guide was knowledgable about astronomy, and good at keeping up an educational dialogue through the trip, and helpful/ensuring everyone's comfort. However, the description on Viator says that there are two stops going up Muanakea, and I think this is misleading. All we did was cross the street, and it was a location I had already been to on the island (across from a popular rest stop), so it doesn't seem that exceptional. The good news is that you have an easy bathroom opportunity. I thought we would be going higher up the mountain (although I knew this was not a summit tour). I would also like the company to incorporate more Hawaiian/indigenous stellar history/stories. For example, the constellations we learned about came largely from a western/European perspective. Since this tour mentions not going to the summit our of respect for Hawaiian concerns, it would be nice to incorporate more of their history/beliefs/culture into this tour.
