The Island of Hawai'i
The Heavenly Hawaii Coffee Farm was wonderful - they gave a free tour and quite a bit of education about coffee farming in general and specifically Kona coffee. One of their resident cats Umi accompanied us on the tour.
The balcony/patio view at the place we stayed was absolutely gorgeous (thank you David and Yuriko!), and we spent a lot of mornings and evenings on it.
On the way to the national park, we came across a popular (which I understand after trying their food!) bakery. Afterwards we went over to the town of Hilo and spent some time exploring it.
We hiked on Captain Cook's Monument Trail right after the afternoon rain, but it was worthwhile. I didn't expect to see so many goats on the trail.
