This tour is the highlight of our Hawaii trip! Not all tours go to the summit, but this one definitely does. We had ample time to get acclimated to the altitude and also enjoy the sunset and see the stars. Gab and Aiden are fantastic guides! Gab is very friendly and helpful, and shared stories along the way. Aiden is very knowledgeable about astronomy, showed us 2 stars plus the moon via his telescope, and show us how to look for celestial objects. Wonderful pictures they took of individual families! They provided us with clean, warning jackets with hoods and gloves. Amazing trip!
