Between its coffee plantations, artsy havens, and Kealakekua Bay—one of the most beautiful spots on the Big Island—South Kona has plenty of activities to occupy a day. Bring a swimsuit and snorkel gear, and hit Kealakekua Bay first thing in the morning. You'll beat the crowds, have a better chance of a dolphin sighting, and see more fish. After a morning of swimming or kayaking, head to one of the great cafés in nearby Kainaliu to refuel.

The winding road leading to Kealakekua Bay is home to a historic painted church, as well as several reasonably priced bed-and-breakfasts with great views. The communities surrounding the bay (Kealakekua and Captain Cook) are brimming with local and transplanted artists. They're great places to shop for gifts or antiques or to take an afternoon stroll.
