Hawaii offers the promise of crystal- clear, azure-blue waters at temperatures averaging over 75 degrees. The temperature of our waters varies only five degrees from the hottest day in August to the coldest day in February. On a bright, sunny day there can frequently be up to 100 feet of visibility underneath the ocean’s surface, creating ideal snorkeling and scuba diving conditions. This is due to the makeup of the ocean floor, which is predominantly lava rock or coral reef with little silt or sand.
Enjoy the spectacular waters first hand while snorkeling or scuba diving. Observe the endangered Hawaiian Sea Turtle and swim with Hawaiian Spinner Dolphins. Keep an eye out for frequent whale sightings. Kayak the serene waters and explore sea caves. Take a Virtual Tour of a Hawaiian Coral Reef
