Two restored camp houses, dating from the days when sugar was the main agricultural crop on the Islands, have been converted into a museum, visitor center, and gift shop. About 3,100 acres of McBryde sugar land have become Hawaii's largest coffee plantation, producing more than 50% of the state's beans. You can walk among the trees, view old grinders and roasters, watch a video to learn how coffee is processed, sample various estate roasts, and check out the gift store. The center offers a 15-minute self-guided tour with well-marked signs through a small coffee grove as well as free guided tours daily. From Kalaheo, take Highway 50 in the direction of Waimea Canyon (west) and veer left onto Highway 540. It's 2½ miles from the Highway 50 turnoff.
