As the first company to specialize in tours to the mountain, Mauna Kea Summit Adventures focuses on stars. Cushy vans with panoramic windows journey first to the visitor center, where participants eat dinner and acclimate for an hour before donning hooded arctic-style parkas and ski gloves for the sunset trip to the 14,000-foot summit. Stargazing through a powerful Celestron telescope happens mid-mountain with the help of knowledgeable guides. Tour, dinner, and west-side pickup cost $212 and runs 364 days a year, weather permitting. You can save 15% by booking online.
