The city of Lahaina on the western coast of Maui is, today, sometimes seen as simply a way to get to the beaches of Kaanapali. If you're just passing through, however, you're missing the town's charms completely.
Lahaina was once the royal capital of the Kingdom of Hawaii, from 1820-1845, and many of the attractions in the historic district date from that era – including the old cemetery, where you'll find royal graves, and a defensive fortress with reconstructed walls. Later, the city's economy was built on the whaling industry. Visitors today, however, come by the thousands to go whale watching rather than hunting.
The Lahaina Historic District is the center of tourism in the town, with several 19th century attractions to check out, and was designated a National Historic Landmark in 1962. In addition to the historic attractions and whale watching, you can also enjoy snorkeling, surfing, sightseeing cruises, and luaus.
