Indulge your senses in an unforgettable journey of sight, taste and sound with a tour of OK Farms. Spanning nearly 1,000 acres, it's the largest family owned farm along the beautiful Wailuku River with its very own private deck overlooking the famous Rainbow Falls. Upon arrival, you'll explore the farm, which grows an abundance of tropical crops such as cacao, coffee, macadamia nuts, lychee, and more. A walk around the surrounding area leads to Spice Road where the scent of cinnamon and nutmeg linger in the air. And a stroll through the coffee and cacao orchard offers a look at how these two Hawaiian favorites are grown and processed. After tasting a variety of fresh seasonal fruits you'll visit the Kaimukanaka waterfall on your way to Rainbow Falls, known for its 80-foot cascade that hits the water below with mist creating a prism of color in the dazzling sunlight.
