This isolated bay is an unspoiled marine sanctuary filled with colorful marine life and coral where you can see, among other fish, whales and dolphins. Tucked along this bay are ancient religious temples and also the historic monument where world explorer Captain James Cook met his fate, according to Hawaii Activities. Archaeological sites are only accessible by rugged foot paths or by kayak.
