Kauai
Kauai, known as the "Garden Isle," is Hawaii's oldest island, constructed millions of years ago by a volcanic explosion. Hiking, snorkeling, ziplining, river kayaking, and even tubing through inner waterways are popular activities for active vacationers on Kauai.
In addition to snorkeling, scuba diving, swimming, and sunbathing, you may take scenic/snorkeling boat cruises along the Na Pali Coast, where you have a good chance of seeing dolphins or trying your hand at kayaking the gorgeous Wailua River.
