With little public transportation, a network of long two-lane highways, and by virtue of its nature (it's really big), the Big Island requires the rental of a car or motorcycle if you plan to do any serious exploring. The two-lane highways along the Kona Coast, Hamakua Coast and through the Volcano area are narrow, packed with tour buses and trucks, and the traffic flows fast. You'll want to be behind either the wheel of a car or the handlebars of a motorcycle — or in a tour bus.

Circle-island tours are popular on other Hawaiian Islands, but on this one, we don't recommend it. Although it's possible to accomplish in one day, the 225-mile trip takes about six hours, leaving no substantial daylight time to explore the island's many attractions. We recommend, instead, that you plan a series of shorter trips — maybe one per day — to destinations of your choice.

NOTE: Don't underestimate how long it takes to get somewhere on the Big Island. Long distances and often traffic-clogged two-lane highways can slow you down.
