Hawaiʻi is the only U.S. state where cacao grows commercially. The archipelago sits just inside the global “cacao belt” that wraps the equator between roughly 20° north and 20° south latitude, and a handful of estates across four islands run working bean-to-bar operations you can visit. (Hawaiʻi Department of Agriculture — Commodities: Cacao)

Most visitors default to Kona coffee when they think about Hawaiian farm tours. Cacao is the other half of that same story. Hawaiʻi’s patchwork of microclimates supports both crops, and in many cases the same family-run estates grow both. Schedules vary by operator, but most run year-round.

One note on scope: most stops here are working farms. The Manoa stop in Kailua is factory-only with no orchard walk. Maui Kuʻia offers a factory experience alongside its farm tour. I’ve flagged which is which. Below is what each tour delivers and what it costs when the operator publishes a rate.

Manoa Chocolate (Kailua)

333 Uluniu Street. The most accessible chocolate tour in the state, and the one factory-only stop on this list (no orchard walk). General admission starts around $25, with discounted rates for kids 5–12 and free entry for children 4 and under. The guided walk covers their bean-to-bar process step by step and ends with a tasting of single-origin bars. Manoa also offers a shorter tasting-only experience. Confirm current pricing and formats on their booking page before planning a trip around a slot. Kailua is a day-trip magnet, so reserve ahead for weekend times. (Manoa Chocolate — Factory Tours)

21 Degrees Estate (Kahaluʻu)

A veteran-owned boutique cacao farm on the windward side, run by Michael and Maria Rogers (Maria is a retired Air Force colonel). Tours run twice a week in small groups and last roughly two to two and a half hours. Each tour includes a chocolate tasting plus a bonus tasting of estate honey from hives on the property. Published tiered pricing is $60 for adults 18+, $38 for teens 13–18, $18 for kids 3–12, and free for under 2. Check the operator’s tours page for current days and times. This tour pairs well with a windward-side driving loop that takes in Kualoa Ranch or the Byodo-In Temple. (21 Degrees Estate — Tours)

Maui Kuʻia Estate Chocolate (Lahaina)

78 Ulupono Street, Suite 1. The largest chocolate factory in the state, on a 20-acre estate in the foothills of the West Maui mountains. Their “Guided Cacao Farm Tour and Tasting” is a 90-minute experience that starts with a short van shuttle to the farm. You get hands-on fruit-harvesting demonstrations and finish with a nine-piece tasting of their chocolate in an open-air hale under the trees. They also run a separate 90-minute “Chocolate Factory Experience” out of their factory store on Ulupono Street for visitors who want the bean-to-bar walk-through without the farm time commitment. Check the operator’s site for current prices. (Maui Kuʻia Estate — Chocolate Farm Tour and Tasting; Maui News — tour reopening, April 2024)

A note on the location: the Ulupono Street factory store is in the Lahaina Gateway / Lahaina Business Park area north of Front Street, well outside the August 2023 fire zone, and it is open. Always confirm current booking windows through the operator’s own site before planning a trip around a tour slot.

Both experiences are family-friendly for ages three and up. The farm tour is not ADA-accessible and involves roughly 20 minutes of walking on uneven, mulched ground with stairs. Book direct through the operator or compare small-group alternatives with Viator tours on Maui.

Original Hawaiian Chocolate Factory (Keauhou, Kailua-Kona)

The state’s first commercial bean-to-bar operation, opened by Bob and Pam Cooper in 1997 and still run by the same family. Tours are offered Wednesdays and Fridays at 9 a.m. and 11 a.m., with advance reservations required; the schedule fills up fast in high season. Admission is $30 for adults, $12 for children ages 6–12, and free for kids under 5. This is a genuine working plantation tour, not a storefront experience. You walk the orchard, see the fermenting and drying, and taste bars milled from beans grown on the same hillside. (Original Hawaiian Chocolate Factory — Tour/Visit)

Puna Chocolate Company — South Kona Farm

79-7378 Hawaii Belt Rd, Kealakekua. Despite the “Puna” in the name, their farm tours happen at their South Kona estate on the Belt Road. Options range from shorter cacao tastings up to longer farm tours that include coffee (the farm grows both) and a four-course luncheon pairing. Check their current booking calendar for prices and times. Longer tours book out further ahead than the tastings. (Puna Chocolate Company — Cacao Farm)

A cacao tour morning plus a Kona coffee tour afternoon makes a natural Kona-side day. Our guide to the best coffee farms and tours in Hawaiʻi covers the coffee half of that pairing in detail.

Lydgate Farms Chocolate Farm Tour (Kapaʻa)

5730 Olohena Road. The biggest time commitment on this list. The tour runs Monday through Friday, with start times at 9, 10, 11, or noon, and lasts three full hours. Tickets start at $145 per person for ages 13+, with kids 7+ welcome (children under 7 are not allowed). The walk covers their botanical orchards with continuous tastings of chocolate and tropical fruit along the way. Lydgate’s estate chocolate has won Gold at the Academy of Chocolate Awards in London and has repeatedly placed at the Cocoa of Excellence Awards. If you only have room for one farm-tour reservation on your Kauaʻi trip, this is the strongest pick for chocolate-first travelers. (Lydgate Farms — Chocolate Farm Tour; awards history write-up)

Kapaʻa is on the east side, roughly 20 minutes north of Lihuʻe airport, so the tour slots in easily on arrival day or as a buffer between beach and mountain days. The farm is well off any tour-bus route, so you’ll want a rental car.

Every farm on this list sells their own bars, and the best souvenirs from a Hawaiʻi chocolate tour are usually the single-origin bars from the estate you just walked. A few notes on what to look for:

“Made in Hawaiʻi” is not the same as “made from Hawaiian cacao.” Many bars sold at ABC stores and resort gift shops are made on-island but use beans imported from Latin America or West Africa. Read the back label. Bars listing a specific Hawaiian farm, estate, or island of origin are the real thing.

Expect to pay more than supermarket chocolate. A premium single-origin Hawaiian bar typically runs $10–$15 for a 2–3 oz bar. Hawaiian cacao yields are small and the volumes cannot compete with global commodity chocolate. The trade-off is a fully traceable bean-to-bar product. (Seattle P-I — Chocolate farms, a sweet spot on any Hawaii itinerary)

Store them cool and dry. Hawaiian bars with a high percentage of cacao butter bloom easily in checked luggage. Pack them in a carry-on when you can, and keep them in a cool, dry spot at home (away from direct sun and kitchen heat).

If you want to keep tasting after the trip, Hawaiian single-origin chocolate on Amazon is a decent fallback between visits.

All six operators work cacao year-round, so there is no wrong season to book a tour. Most tours cover enough of the bean-to-bar chain — fermentation through roasting — that timing your trip to a specific harvest window isn’t necessary.

A schedule that covers two stops in one trip is easier than it looks. Oʻahu plus Kauaʻi is one natural pairing. Maui plus Big Island is the other. Either combo lets you see one boutique estate and one larger production operation in the same week. If you are tasting coffee on the same trip, many Kona-side cacao farms sit within a few minutes’ drive of established coffee estates, so a farm tour morning plus coffee tour afternoon day works especially well on the Big Island.

Reservations are required for the guided tours on this list. Book ahead, especially in winter and spring-break periods when slots go fast. Puna Chocolate’s shorter tastings sometimes allow walk-ins; confirm on their calendar before you count on it.
