An excellent way to sample a wide variety of organic exotic local fruits is to visit the farmers markets.   There are farmers markets all over the island on different days of the week.   On Monday it's in Koloa at the ballpark on Maluhia road at noon. On Tuesday it's in Hanalei at Waipa field just past town at 3:30.   On Wednesday it's in Kapaa at the ball park parking lot off Olehena road at 3:00.   On Thurday it's in Kilauea at the Neighborhood center parking lot on Keneke road at 4:30.   On Friday it's in Lihue at Vindinha Stadium Parking lot on Hoolako road at 3:00.   On Saturday there are three markets, one in Kekeha at the Neighborhood center on Elepaio road at 9:00, one in Hanalei at the Neighborhood center at 9:30, and one in Kilauea next to the post office at 11:30.
