Kahului Airport  (IATA: OGG) is the main airport for the island of Maui, and the second largest commercial airport in the state. It is a secondary hub for Hawaiian Airlines, which provides interisland service to Kahului from the other major airports in the state. Several major U.S. airlines also provide non-stop service to Maui from the West Coast and beyond. Kahului airport can be reached non-stop from Anchorage, Calgary, Chicago, Dallas, Denver, Edmonton, Hana, Hilo, Honolulu, Hoolehua, Kamuela, Kapalua, Lanai City, Lihue, Los Angeles, Oakland, Phoenix, Portland, Sacramento, Salt Lake City, San Francisco, Seattle and Vancouver.
To get to Lahaina and Kaanapali, where most major hotels are located, exit the airport and follow route 380 to its junction with route 30, and turn left on route 30 toward Lahaina. For Kihei and Wailea, follow the above instructions and turn left on route 31 about a mile (1.6 km) from the route 380 junction.
When departing from Kahului Airport for the U.S. Mainland, all baggage must be inspected by Hawaii State Department of Agriculture inspectors at the airport. Be advised that fresh fruits (with the exception of pineapples and treated papayas) are prohibited from leaving the islands to prevent the spread of fruit flies. Remember that this inspection occurs before you get to your gate, so you won't be able to enjoy your last fruit while waiting for your departing flight.
While Maui has a basic public transportation system , many places are not accessible by bus, and most visitors rent a car. Fortunately, renting a car in Hawaii is relatively inexpensive, except during the holidays. The resort areas around Kihei, Wailea and Lahaina also have a bus that connects the towns with nearby shopping and attractions. If you want to drive green, you can rent a car powered by vegetable oil (biodiesel), or a gas hybrid that gets 50 mpg, or even a plug in electric car from Bio-Beetle. http://www.ecorentalcar.com
Be aware that most locals refer to the roads not by number but by name, and will likely not understand if you ask for a road by number. For example you would never hear someone refer to Piilani highway as "route 31" or "highway 31."
Lahaina Kaanapali Railroad
Also called the Sugar Cane Train, the Lahaina Kaanapali Railroad is both an attraction and a means to travel (slowly) between the Kaanapali resort area and Lahaina Town. The official Lahaina Kaanapali Railroad web site offers more information as well as discounted tickets.
Haleakala National Park offers alpine wilderness and stunning views of Maui and beyond (from the summit you can see five of the eight main islands, more than are visible from anywhere else in Hawaii). Two entrances, one from Highway 36 and one from Highway 37, go to separate parts of the park.
Wainapanapa State Park  has black sand beach, sea arch, sea caves, a small blowhole to see. In Hana at end of Wai‘anapanapa Road off Hana Highway (Highway 360), 52.8 miles (85 km) (3 hour drive) east of Kahului Airport.
Iao Valley State Monument is very green. You can climb up 0.6 miles (1 km) on paved trail to a view of the ocean, Iao Needle, etc. or climb down to a garden, stream, etc. From Kahului go west on ‘Iao Valley Road (Highway 32) through Wailuku to the end of the road.
There are many trails on Maui including a couple of trails in Io Valley State Monument  and several in Haleakala National Park. The upper part of Haleakala National Park bears no resemblance to the lower. The crater at the summit, some 19 square miles, draws millions of visitors each year. Hike within it on miles of trails past cinder cones and lava caves or you can stroll from roadside turnouts to sky-high overlooks. The drive to the top is the steepest in the world and along Haleakala's slopes are eight biological zones, designated as an International Biosphere Reserve.
Canoeing and Kayaking
In Hawaii a canoe is an ocean-going outrigger. They also have double hull canoes that are a bit like catamarans. There are canoe clubs that will sometimes take out visitors for a reasonable donation.
Many businesses would be happy to introduce you to kayaking.
There are many luaus in Maui, which feature Polynesian singing and dancing. Most feature buffet dinners. Here are some of the best known.
There are mountain bike trails in Makawao State Forest.
This can be one of the most affordable activities on Maui. Some favorite spots include:
Use caution to decide when and where to snorkel. Educate yourself about riptides and avoid choppy seas, which could bash you against coral or rocks.
Take the road trip on Hwy 36 (Hana Hwy) stopping on the road to see waterfalls, lush greenery and beaches. Some of these are not visible from the road, but most are a relatively short hike off the road. A private arboretum and botanical garden (with an entrance fee) called "Garden of Eden" around the 10-mile marker has peacocks, bamboo gardens and view of Puohokamoa Falls. The round-trip will be difficult to complete in one day, so stay over in Hana to break it into two days. Wainapanapa State Park, 2 miles (3 km) east of Hana, has cabins to offer. There are other private nicer places to stay, also in and around Hana.
The Road to Hana is something that must be experienced at least once in a lifetime. Keep in mind that some of the locals from Hana make the long commute to work in Kahului each day. If you see a local vehicle approaching from behind, pull over and let them pass. By the same token, locals' familiarity with the route can lead them to cut across corners (even blind corners) swerving back into their lane at the last minute, so take corners slowly and watch for oncoming traffic that may have encroached upon your lane. Also, don't trespass! If you respect the land and the people, you'll find open arms and acceptance.
Note that it is possible to drive all the way around the island by continuing past Hana instead of going back the way you came. Rental car companies strongly discourage this and state that the rental car contract is voided if you drive there. The road itself is one lane and paved virtually the entire way, (not all of the road is paved as of 9/24/12)although in some places the asphalt can be patched and rough, requiring road speeds of 10 mph or less to avoid damaging a normal car's suspension. Off-road vehicles and jeeps will find it fairly easy going. The area is very beautiful, with soaring cliffs and views over the sea and glimpses of the nearby Big Island on the horizon, but it is dry, desolate and remote, with little traffic, no services, and unreliable cell phone service.
Visit Lanai or Molokai
As one would expect from a tourist mecca like Maui, there are several areas to find good shopping. Also as one would expect, the prices can be quite inflated. ABC Stores can be found all over Maui and the other Hawaian Islands and offer souvenirs and beach junk (such as sunscreen and straw mats) at potentially lower prices than tourist traps. In Lahaina, a good place to "walk the shops", find Old Lahaina Book Emporium. Kaanapali has Whaler's Village Shops and Restaurants, home to lots of stores and restaurants, including plenty of high-end merchandise such as Coach and Tiffany. Paia is a small artist and aging hippie colony with a reasonable and varied mix of shops and galleries worth your time, as well as restaurants. It is located just before Mama's Fishhouse Restaurant. A nice open air mall can be found in the Wailea luxury area. On the way you can stop by Kihea at one of two flea market type shopping areas.
Check the Eat section on the pages for the various towns listed under Cities above
Fresh produce is widely available at road side stands. Banana bread, coconut candy, smoothies and seasonal fruit are all highlights of a drive around Maui.
Check the Drink section on the pages for the various towns listed under Cities above. Also consider the bars at the hotels and resorts, which may have happy hour specials.
Before choosing an accommodation consider where you would like to spend your time. Also consider whether a hotel, resort, condominium or bed-and-breakfast best match your style and budget. Then check the Sleep section for the many towns on the island under Cities above.
To get from Maui to the other Hawaiian Islands usually involves a short plane flight. If you want to go to Honolulu you will find frequent non-stop service. Most other destinations offer a couple of non-stop flights a day or a stop in, you got it, Honolulu.
Ferries run 5 times a day between Lahaina and the island of Lanai. Each way takes approximately 45 minutes, and costs $25 per person per direction. During high winds the boat ride can be particularly rough, so bring something for seasickness if you don't do well on boats. Cruise ships are also an interesting option.
When leaving Maui for the U.S. Mainland, all baggage must be inspected by U.S. Department of Agriculture inspectors at the airport. Be advised that fresh fruits (with the exception of pineapples and treated papayas) are prohibited from leaving the islands to prevent the spread of fruit flies. Consult the U.S. Department of Agriculture  for more details. Bags are inspected by X-ray. At Kahului Airport, be prepared to submit to three checkpoints on the way to your Mainland flight: having your checked bags X-rayed for agricultural items in the ticket lobby, the TSA security checkpoint, and inspection of your carry-on baggage for agricultural items on the way to your gate.
