Honolulu to Kailua-Kona Road Trip: Ultimate Island Guide

The route from Honolulu to Kailua-Kona is unique: you must first fly from Oahu to the Big Island (Kona or Hilo airport) then drive. There is no bridge or ferry. The flight takes about 30-40 minutes, and the subsequent drive from Kona Airport to Kailua-Kona is a short 15-minute hop. This guide focuses on the driving portion on the Big Island, exploring the best stops between Kona and Kailua-Kona, as well as day trips from Kailua-Kona.

The flight from Honolulu to Kona Airport is the first leg; it's a quick inter-island hop. Once you land, the real road trip begins. The drive from Kona International Airport to Kailua-Kona takes you along the Queen Ka'ahumanu Highway (Route 19) hugging the stunning Kona coast. This 8-mile stretch offers immediate ocean views and sets the tone for your Big Island adventure.

Driving on the Big Island is generally safe, but be aware of unique conditions. Roads can be narrow and winding, especially on Highway 11 south of Kailua-Kona. Watch for livestock (cows) on some rural roads, and always yield to pedestrians. The Kona coast has sunny weather, but sudden rain showers can create slick roads. Use headlights in rain and reduce speed.

• Always wear seat belts; child seats are required per Hawaiian law.
• Do not leave valuables in plain sight in vehicles, especially at trailheads.
• Cell phone reception is spotty in remote areas; download maps offline.
