Arnott’s Lodge - Mauna Kea Adventures
"Arnott's Lodge and Mauna Kea Adventures offers guided tours to the summit of Mauna Kea from Hilo on Hawaii's Big Island. This nearly 14,000-foot peak is a sacred site for native Hawaiians and a prime location for astronomical observatories. The tour takes guests to the summit for stunning views and a unique star-gazing experience. Along the way, there are stops at the Onizuka Visitor Center for acclimatization and brief stops at sites like Rainbow Falls. Tours vary in duration, including evening, sunrise, and daytime options​."
