Coffee Farms on the Big Island

“Kona coffee” is a legal place name, not a style. Under state rules, Kona means the North Kona and South Kona districts on the island’s west side, where the slopes of Hualālai and Mauna Loa catch a belt of persistent cloud. The University of Hawaiʻi’s Rainfall Atlas describes that cloud-and-rain zone as home to the farms that produce Kona coffee. The farms spread across the upcountry slopes above Kailua-Kona, from Holualoa south to Hōnaunau, so two or three fit easily into one morning.

Free tours versus booked tours

• Drop-in and free: Greenwell Farms in Kealakekua, a family farm dating to 1850, runs free tours daily with tastings of its 100% Kona coffees. Mountain Thunder on Hualālai offers free guided tours of about 20 minutes, with samples of several roasts.
• By reservation: Hula Daddy in Holualoa runs hour-long tours of the orchard and roasting room on weekday mornings, finishing with a guided tasting.
• Booked ahead: two farms sell their tours on Viator, which locks in a time slot.

Reading a coffee label

A bag that says “Kona blend” can contain mostly foreign coffee. Under current Hawaiʻi labeling rules, blends must state the percentage from each origin, and a 10% Kona blend is still legal. That changes: from July 1, 2027, a blend using a Hawaiʻi region name must contain at least 51% Hawaiian coffee. If you want the real thing, look for “100% Kona coffee.” Buying at the farm is the surest way to get it.

Time your visit

The Kona Coffee Cultural Festival, now in its 55th year, runs November 6–15, 2026, with farm events across the coffee belt. Any time of year, pair the drive with Puʻuhonua o Hōnaunau at the bottom of the hill.
