1. MAUI: The Road to Hana
This may be one of the most beautiful drives on the planet. Plan a full day for the roundtrip and take your time to enjoy the adventure...too many drivers speed along thinking that the tiny village of Hana is the goal only to be seriously disappointed. From Kahului take 36 east, just past Pauwela the road will narrow and become State Route 360.  Pack a picnic lunch, bring your bathing suit, towels and change of clothes. Sites worth seeing along the way include Keanae Arboretum, Waianapanapa State Park, Hana Coast Gallery, Red Sand Beach and the Hasegawa General Store.

2. KAUAI: Grand Canyon of the Pacific
Head west from Kauai's main town of Lihue along State Rte 50 to the Hawaiian village of Waimea. You'll travel north on Rte 550 which runs alongside the Waimea Canyon...known as the Grand Canyon of the Pacific. The road leads through Kokee State Park and ultimately the Kalalau Lookout. There are several spots to stop along the way up and they are all worth a visit for spectacular views of the canyon below. There's a small restaurant, a lodge, the Kokee Natural History Museum and numerous trails. If hiking, come prepared as this is the wettest spot on the planet (see Kauai, Yes We have Rain.)

3. NORTH SHORE OAHU : Route Of The Surfers
If you ever owned a Beach Boys album or surfboard... you may know about Waimea Bay and Sunset Beach on Oahu's North Shore. During the winter months (Nov-Mar) waves of 15-20 feet are common  along beaches with names like Banzai Pipeline. Waimea Bay has monsterous waves that can make  the ground shake when they break. It's also the sight of the Waimea Valley Audubon Society and  stunning botanical gardens, nature trail and waterfall .From Honolulu you’ll travel north on H-2 and then pick-up Route 99 (Kamehameha Highway) heading towards the North Shore. You meet up with  Route 83 which circles nearly all the way around the entire island of Oahu. 

4. MAUI: Upcountry and Haleakala National Park
Nothing can prepare you for the amazing (some say religious) experience of watching the sunrise over the edge of the crater of Haleakala...Maui's dormant volcano that rises over 10,000 above the Pacific. You'll need to leave quite early to get there in time plus remember to dress warmly as the temperatures will be in the 30's at this altitude. The park has many overlooks and a fascinating visitors center. It is also home to the endangered Nene (Hawaiian Goose) and the fragile Silversword plants. Your return trip down the mountain could include a visit to the Tedeschi Vineyards and the Kula Botanical Gardens. To get to the top of the volcano, take the Haleakala Highway (Route 37), at Pukalani, Route 377 will branch off to the left and begin the steep climb to the top. After 6 miles, look for signs to the entrance to the national park and its narrow winding road.
         
5. HAWAII: Big Island Circle Route (Volcanoes to Waterfalls)
The Big Isle of Hawaii is home to the two largest mountains on the planet Mauna Loa and Mauna Kea and the active volcano of Kilauea. As most hotels are on the West side along the Kona Coast...it will  take a full day to make the grand circle of this diverse island. Highlights include the Hawaii Volcanoes National Park and the Chain Of Craters Road, Mauna Loa Macadamia Nut Farm, the town of Hilo, Hawaii Tropical Botanical Garden, Akaka Falls, and the Parker Ranch. From the Kona Coast area. You’ll take Route 11 to Volcano National Park. Later in the town of Hilo, look for Route 19 and travel north about 13 miles to the village of Honomu. There will be signs for the turnoff to Akaka Falls State Park…  the highest falls in the state. Route 19 continues north and west all around the island, returning you to the Kona Coast side of the Big Island.

6. MOLOKAI
This island was the home to the Belgium priest, Father Damian, who spent years ministering to those suffering from Hanson's Disease (leprosy) at the colony at Kalaupapa. No independent touring is allow at the former colony, however for those over 16 years old, there are organized mule rides that descend along the 1700-foot precipice among the tallest sea cliffs in the world.(See the Molokai Cliff Hanger post)  Just past the stables, the road continues to the Kalaupapa Lookout that offers incredible views of the cliffs and colony below. When driving back, you can stop at Purdy's Macadamia Nut Farm in the village of Hoolehua. The main town on Molokai is Kaunakakai, and you take Route 460 west to the junction with Route 470... take this road north to the Kalaupapa Lookout.
 
 7. NORTH SHORE OF KAUAI
The North Shore of Kauai is where Hollywood came to film the movie South Pacific. Driving north from Lihue on Route 56, there are many sights worth seeing on your drive such as the Kilauea Point National Wildlife Refuge & Kilauea Lighthouse (Home to hundreds of boobies, albatrosses and Frigate birds), the charming village of Hanalei, the Hanalei River and Hanalei Valley Lookout, and Lumahi Beach where the movie was filmed.  A short but slippery hike away are the Maniniholo Caves.  

8. Around The WEST MAUI MOUNTAINS
For those who are staying in the Lahaina and Kaanapali area a day trip around the West Maui Mountains make for a wonderful adventure. Pack a picnic and don't forget you swim suit and towels and head north on Route 30.  Just past Fleming Park there a steep path down to Mokuleia Beach and its Underwater Marine Sanctuary, which offers great snorkeling. Further ahead is Honolua Bay with its black rocky beach. Continuing around the Northwest tip of Maui, the highway becomes Route 340 with spectacular views and a sense that you have the whole island just to yourself. Once you’re on the other side of the mountains, stop at the I'ao Valley State Park for glimpses of the famous I'ao Needle.  

9. OAHU: Through The Tunnels
For those making their base in Honolulu, there is plenty to see just outside of town.  Before heading northeast on Route 61, you could visit the National Cemetery Of The Pacific... known as the Punchbowl. Once on the highway, look for signs for the Pali Lookout...  a small park offering breathtaking views of eastern Oahu. The highway travels under the Koolau Mountains through an impressive tunnel. Head south along Route 72 (Kalaniana'ole Highway) which provides impressive views of the Pacific. For those with extra time Sea Life Park is along the way. The highway passes by Koko Crater and the stunning Hanauma Bay Nature Preserve (Note: The entrance to the Bay is heavily regulated by park officials due to overcrowding) and then around the famous landmark Diamond Head before returning to Honolulu.

10. HAWAII: Big Island Northwestern Tip
The Northwestern tip of the Big Isle, Hawaii, is rarely visited by tourists. For those staying along the Kona Coast, take Route 19 north.  You’ll pass Hapuna Beach which is worth a stop when the waters are calm as it is frequented by endangered green sea turtles .Continue onto Route 270 to Lapakahi State Park to get a glimpse of the Hawaiian ways of 600 years ago. Heading all the way to the tip of the island you'll discover Mookini Heiau---the birthplace of Kamehameha I and the site where legend says the priest Paao first arrived from Polynesia. Spectacular views await at the end of the road at the Pololu Valley Lookout. Return back to Kona via Route 250 with impressive views of the lush green Kohala Mountains.
