The Macadamia Nut Farm in Oahu is a popular spot on our Ohana Circle Island Tour. Aside from over 15 types of Macadamia nuts and Kona Coffee samples, make sure to check all the fun happening outside. Here is a sign found on the Macadamia Nut farm that can help any lost tourists find their way home! Definitely one of the best things to do in Oahu!
