Tours - We conform to all current State of Hawaii COVID regulations in the best interest of our staff and visitors. We are pleased to be able to offer tours, every 30 minutes, of our mill along with discussion of all the processes entailed in growing, processing, and roasting some of the best coffee on Earth. Additionally, we offer fee based ($10 per family group) Nature Trail Walk including native vegetation, coffee plantation, observation deck and lava tubes. For the immediate future we are no longer able to offer 4X4 Plantation Tours or the RoastMaster Experience. We appreciate your understanding and patience during this trying time.

At this time, due to COVID restraints, we are not able to offer our Private 4X4 Plantation Tours or our Roastmaster Experience. Please check back for updates.


This could be the highlight of your trip to Kona. After taking our 30-minute orientation tour, and learning about Kona coffee growing, harvesting, milling, and grading you will spend approximately 90 minutes with Mountain Thunder Coffee Plantation’s master roaster. This is an intimate group (limit six people) or one-on-one experience.

  • Learn about and participate in the selection of the green coffee you will be roasting.
  • Understand roasting theory as well as the basic operation of the roasting equipment.
  • Taste our various Kona coffee roasts, select which roast you prefer.
  • Work side-by-side with our Roast Master to roast the green coffee you selected
  • Manage and create your own personal roast
  • Package your roasted coffee in 8 oz. or 16 oz. packages to take with you, or we can ship to your home (at additional cost).
