Rent-a-cars are available at the airport and t here are three quick ways to get to Kailua.
To take the new H3 Freeway: At the airport freeway entrance, move to the left lanes and take the Waianae exit on H1 WEST. Follow the road towards Pearl City. As you approach Aloha Stadium, move towards the right side of the freeway and watch for signs to Hwy 78 and H3 to Kaneohe. Take the new H3 freeway through the long Halawa Tunnel north past Kaneohe towards MCBH (Marine Corps Base Hawaii) at the end of the road. Get off at Exit 14 or Exit 15 to Kailua. This is a fast and beautiful new road. We highly recommend it.
To take the scenic Pali Highway 61: At the airport freeway entrance, move to the right lanes and take H1 EAST. Follow the freeway east and move to the left lanes. Follow the H1 as it forks left to Honolulu. About a mile further ahead, the highway merges with Hwy. 78. Continues ahead about four miles. Get in the right lanes and watch for the Pali Highway exit. Turn left to go north on Pali Highway through the Pali Tunnels for 13 miles to Kailua. This is one of the most scenic roads on Oahu through the Nuuanu rain forrest. Make a quick stop at the Pali lookout for fabulous views and photos of the Windward side.
