This was such a wonderful experience. Our tour guide was a super nice and had some great information about the site (he was also hilarious and honestly worth the trip alone), and the sights where absolutely incredible. While the stars weren't great that night, the view of a sunset above the clouds while it was snowing off and on was unreal, and the view of the full moon was beautiful.
Also, the snacks where on point.
The photography was something we didn't know the trip included, but was really fun to do as well.
However, be aware the altitude is high, and you will need to walk a bit slower and acclimate.
But, all in all, it's one of the coolest things you can do on the big island.
