Right off the Mamalahoa Highway, the Kona Coffee Mill and Museum sells Kona Coffee, macadamia nuts, T-shirts, and heaps of Hawaii souvenirs. A perfect pit stop, you will find coffee samples and a small cafe on the lanai (porch) of the red farm building. A self-guided tour is available around the small establishment. You will observe beans drying in the Hawaiian sun below the shop and cafe. A small lava tube invites visitors to walk through a short tunnel. Several coffee plants grow on the property so you can see how they grow their berries.
