Lonely Planet review
Whether young or old, triathlete or couch potato, everyone appreciates the island's most thrilling, easy to access (and admittedly busy) snorkeling spot which also boasts offshore surf breaks. Protected by an ancient breakwater (which, according to legend, was built by the menehune, or 'little people'), the bay is pleasantly calm and shallow. You'll spot tropical fish and honu (green sea turtles) without even trying. The lifeguard-staffed park has outdoor showers, restrooms, drinking water, snorkel and locker rentals and picnic tables.
Kahaluʻu can be too popular for its own good, with snorkelers literally bumping into one another. The salt-and-pepper beach (composed of lava and coral sand) is often a mass of humanity, which you may find convivial or nauseating, depending. Come early; the parking lot may fill by 10am. Treading lightly is also important: follow coral-reef etiquette and stay back at least 20ft from sea turtles.
When the surf's up (and it can rage here), expert surfers challenge the offshore waves and avoid strong rip currents on the bay's north side near the church. When conditions are more mellow, beginners can learn to surf or go stand up paddling (SUP) here.
