Maui: What to Pack

This is an excerpt from Frommer's Maui 2010:

Maui is very informal: You'll get by with shorts, T-shirts, and sneakers at most attractions and restaurants; a casual sundress or a polo shirt and khakis are fine even in the most expensive places. Dinner jackets for men are required only in some of the fine-dining rooms of a very few ultraexclusive resorts, such as the Lodge at Koele on Lanai -- and they'll cordially provide you with a jacket if you don't bring your own. Aloha wear is acceptable everywhere, so you may want to plan on buying an aloha shirt or a muumuu (a Hawaiian-style dress) while you're in Maui.

So bring T-shirts, shorts, long pants, a couple of bathing suits, tennis shoes, and rubber water shoes or flip-flops. Don't forget a long-sleeved cover-up (to throw on at the beach when you've had enough sun for the day). If you plan on hiking, bring hiking boots and several pairs of good socks. You might also want to bring binoculars for whale-watching.

The tropical sun poses the greatest threat to anyone who ventures into the great outdoors, so be sure to pack sun protection: a good pair of sunglasses, strong sunscreen, a light hat, and a canteen or water bottle if you'll be hiking -- you'll easily dehydrate in the tropical heat, so figure on carrying 2 liters of water per day on any hike. Campers should bring water-purification tablets or devices.
