Kahaluu Beach Park is on the Kona Coast, just south of Holualoa Bay and north of Kealakekua Bay, and right on scenic Alii Drive. It is a small, sheltered cove that is one of the best snorkeling and diving spots on the Big Island. Even though this is not a marine conservation district and fishing is allowed, there is a remarkable variety of colorful tropical fish in its waters. Kahaluu Beach on the Big Island reveals large schools of sturgeon, soldier fish, parrot fish, eels, and much more. These fish are so accustomed to snorkelers that they seem almost tame. Outside the reef that protects the beach, divers also can see tuna, marlin, sea turtles, and playful dolphins.

The reefs and rock outcroppings make good tide pools and lagoons at low tide, and Kahaluu Beach on the Big Island is a good family beach both for this reason and because of the sea wall that keeps the waters calm and the waves gentle. The entire cove is quite shallow, rarely reaching depths of more than ten feet. Because of this, the sun can penetrate all the way to the bottom, which produces the healthiest of coral. Facilities at Kahaluu Beach Park include restrooms and showers, picnic pavilions and tables, food stalls, equipment rental concessions, and lifeguards. Additionally, as you are right in the town of Kailua Kona and on the main part of Alii Drive, there are plenty of other attractions quite close by, including dining spots, shops, and boutiques.
