ʻImiloa Astronomy Center of Hawaiʻi

ʻImiloa, which means 'exploring new knowledge,' is a $28 million museum and planetarium complex with a twist: it juxtaposes modern astronomy on Mauna Kea with ancient Polynesian ocean voyaging. It's an educational, if rather pricey, family attraction and the natural complement to a summit tour. One planetarium show is included with admission.
