Hamakua Macadamia Nut Company

It's a tourist stop, but a darned good one, featuring a spanking-clean factory, gift shop and generous free samples. This eco-conscious company generates much of its energy needs from solar power and a little bit from ground mac-nut shells. The Hamakua-grown nuts are excellent in quality and reasonably priced. To get here, turn mauka (inland) just north of Mile 4 on Hwy 270.
