The cheapest way to reach Lanai is via ferry, which runs five times a day, 365 days a year. It leaves Lahaina at 6:45 and 9:15am, and 12:45, 3:15, and 5:45pm; the return ferry from Lanai’s Manele Bay leaves at 8 and 10:30am, and at 2, 4:30, and 6:45pm. The 9-mile channel crossing takes between 45 minutes and an hour, depending on sea conditions. Reservations are strongly recommended. During winter, the trip doubles as a whale watch. You can walk from the harbor to Hulopoe Beach, but if you want to explore the island further, you’ll have to rent a car or book a tour.
