Maui Tropical Plantation covers about 60 acres, and was originally designed to turn the island's rich agricultural history into a tourist attraction. There is a tram ride you can take, which includes a narrated tour of the plantation and historic information. You'll learn about crops for which Maui is famous – sugar cane, pineapple, coffee, bananas, and macadamia nuts, among other things. You can even try your hand at husking a coconut.
Maui Tropical Plantation is open daily from 9am-5pm, and admission is free. The tram rides depart every 45 minutes throughout the day – the first is at 10am and the last at 4pm – and tram rides cost $16 for adults, $6 for children ages 3-12. You can take the Maui Bus to reach the plantation – the bus stop is about a block from the entrance.
