Entry to the stay was a bit hard to find for us, as we arrived at night. The place is behind the museum (same building just at the back of it). We had a bit of a hard time figuring out park situation, too (again, since it was dark) but a friendly neighbor came out and helped us.
It was a cute and unique little stay. Every night we were greeted by a ginger cat.
Could see stars pretty clearly from there and felt secluded. We could hear a lot of coqui frogs and crickets.
Super close to Waipio valley (5 min drive).
