Kahalu’u Beach Park is one the most popular snorkeling spots on the Big Island of Hawaii. While we recommend Two Step and Kealakekua Bay as two of the best, Kahaluʻu Bay has its own charm.
The beach park is located in calm water only minutes drive south of Kailua-Kona. Its easy location makes it the perfect place to snorkel if you are staying near Ali’i Drive, or in one of the hotels around the waterfront.
The bay itself is well-protected by a fringing reef, providing safe, calm waters for your snorkeling adventure. The water is relatively shallow, at about 4-5 feet deep. Green sea turtles are often seen in the bay as they like to sun themselves on the rocks.
Some of the sea life you might see when snorkeling include: sea urchins, octopus, eels, turtles, and of course plenty of tropical fish such as yellow tang, parrotfish, rainbow fish, and more.
Take care to snorkel in the south part of the bay. Traditionally, the north part of the bay is where surfers congregate. But there’s plenty of room for snorkelers and surfers alike!
Free parking is available at the beach park. There are also picnic tables, showers and bathrooms, and snorkel rentals. Lifeguards are on duty from 9:30am–4:45pm every day.
Keep in mind that this is a very popular snorkeling destination because of its accessibility to downtown Kona. During the busy season (Nov-Mar) it can get crowded. Your best strategy is to arrive as early as possible to avoid the crowds. The ocean will be at its most calm first thing in the morning before the wind changes to onshore.
The best snorkeling is found in the cove directly out from where you first enter the water. The water is a little clearer further out, due to the fresh groundwater that comes up through the sand near the shoreline causing a blurry effect in the water.
When the tide goes out there are plenty of shallow tide pools to explore in amongst the rocks. The park also has large pavilions for added shade and the beach park is the perfect place to bring a picnic lunch. Don’t have a car? The beach park is close enough to Kailua-Kona you can walk to it (if you’re staying nearby), cycle to it, or make use of the Kona Trolley!
