Deep Research Report

Last updated: April 23, 2026

What it is

Big Island Abalone (Kona Aquaculture Inc) is the largest abalone aquaculture farm in the United States, spanning 10 acres near Kailua-Kona on the Big Island of Hawaiʻi. The farm raises premium Japanese "Ezo" abalone using a sustainable system that pumps pure, cold, and nutrient-rich seawater from 3,000 feet below the Pacific Ocean off Keahole Point. This deep ocean water, along with dulse algae grown on-site for feed, contributes to the abalone's optimal taste, texture, and color. The farm also has a food truck and a DIY barbecue site, offering visitors various abalone meals and the opportunity to grill fresh seafood and local ingredients.

Visitor experience

Visitors can take a guided farm tour to learn about abalone farming, the history of abalone, and the sustainable aquaculture methods employed. The 60-minute tour includes insights into the abalone life cycle, observation of baby and parent abalone, and sometimes a hands-on experience with abalone and other sea creatures. Tours typically conclude with a tasting of grilled abalone and the opportunity to purchase abalone and other sea vegetables like sea grapes. Many visitors describe the tour as educational, informative, and interactive, appreciating the knowledgeable guides. Beyond the tours, guests can visit the on-site food truck, which offers various abalone dishes like steamed abalone with sauces and abalone poke, or utilize the Kona Barbeque facility to cook their own selection of fresh seafood and local produce.

Logistics

  • Area: Big Island Abalone is located in Kailua-Kona, specifically within the Natural Energy Laboratory of Hawaii Authority (NELHA) Kona Coast Ocean Science and Technology Park.
  • Access: The farm is a short drive (about 5 minutes) south from Kona International Airport (KOA) and under 15 minutes from Kailua-Kona town via Highway 19. Visitors should turn onto Makako Bay Drive, following signs for NELHA, and drive approximately one mile toward the ocean. Public bus service (Route 202) is available to Makako Bay Drive, followed by a 15-minute walk. Ride-sharing services like Uber or Lyft are also options.
  • Reservations: Reservations are required for farm tours.
  • Timing: Guided farm tours are typically 60 minutes long. As of November 3rd, tours are offered Monday through Friday at 10:30 am, 12 pm, 1:30 pm, and 3 pm. The farm office is generally open Monday to Friday from 8 am to 4 pm, and the food truck operates Monday to Friday from 10 am to 4:30 pm. The farm is closed on weekends for tours and gate sales, though previous information indicates weekend tours and food truck operation. It is advisable to verify current operating hours and tour schedules directly with the farm due to recent updates on weekend availability.
  • Parking: Free on-site parking is available.
  • Permits: No special permits are required for visitors taking the tour.
  • Likely duration: The guided farm tour itself is one hour. With time for arrival, tasting, and potential purchases, visitors should allocate 1.5 to 2 hours. If also utilizing the food truck or DIY BBQ, the duration could extend to a half-day activity.
  • Activity Type: It functions well as a quick stop for a tour and tasting, or a longer half-day activity if combining the tour with a meal at the food truck or the Kona Barbeque site.

Safety and cautions

The tour involves walking, but it is generally described as easy and relaxed, with most areas covered by canopies, providing shade. Comfortable walking shoes are recommended. While the tour is family-friendly, children should be accompanied by an adult, especially due to the outdoor and potentially hands-on nature of the activities on a working farm. Visitors with specific accessibility needs should contact the farm in advance, as some farm and aquaculture sites may have uneven terrain.

Editorial take

Big Island Abalone is an excellent choice for travelers seeking a unique, educational, and culinary experience beyond typical Big Island attractions. It's particularly appealing for foodies, those interested in sustainable agriculture, and visitors who enjoy learning about local industries. It offers a fascinating insight into aquaculture and the production of a gourmet delicacy.

Travelers who might skip this activity include those with little interest in seafood or agricultural processes, or those on a very tight schedule prioritizing traditional scenic or beach activities.

It's important not to confuse Big Island Abalone with the entire Natural Energy Laboratory of Hawaii Authority (NELHA) facility. While located within NELHA, Big Island Abalone is a specific farm offering its own distinct tour and dining experiences. Other operations within NELHA may offer different tours (e.g., Kona Sea Salt, which is nearby).
