A hugely successful boutique crop, Hamakua Mushrooms are favored by top chefs statewide. Its signature specialty mushroom, the Ali‘i Oyster, is cultivated in bottles and immediately recognizable by thick meaty stems and smooth, fawn-colored caps. The reasonably priced guided tours are very informative, covering cultivation, production and the owners' circumstances in starting a mushroom farm. Enjoy a sample taste at the end.

This all-indoor farm and production plant is all-solar powered and uses an ecofriendly eucalyptus growing medium.
