Snorkeling Guide to Honokohau Beach Big Island

Honokohau Beach snorkeling on the Big Island offers a different experience than more popular Kona locations like Kahalu‘u Beach Park. It generally draws lighter crowds, providing more space to navigate the water and observe marine life. Families frequently spot reef fish and sea turtles in the rocky areas within Kaloko-Honokōhau National Historical Park, near the harbor. The primary challenge for families is the rocky entry, which necessitates reef shoes and careful footing. This can be difficult for young children or new snorkelers if they are not prepared.

Access and Vehicle Storage

Free parking is available within Kaloko-Honokōhau National Historical Park, either at the visitor center or at the south entrance by Honokohau harbor. The parking area at the south entrance often fills by 10:00 AM on many weekend mornings. From the parking near the harbor, expect a 5-10 minute walk over mixed terrain, including dirt paths and some rocky shoreline, to reach ocean access points. This path is not paved throughout, so plan for carrying gear.

Entering the Ocean

Entry points for Honokohau Beach snorkeling are located along the rocky edge near the Honokohau harbor area and within the Kaloko-Honokōhau park sections. Look for a less abrupt spot, typically a small cove or a flatter rocky shelf, usually within 50 yards of the south entrance parking area. Water visibility can range from 10 to 20 feet, depending on surf and currents. Conditions are generally calmer with better visibility before 10 AM. Afternoons often bring increased wind chop, which can reduce underwater visibility and make entry more difficult. Be aware of sea urchins on the rocky entry points and shallow reef; sturdy reef shoes are essential for foot protection.

Beneath the Surface: What to See

From the primary entry point near the harbor, swim north along the rocky shoreline, staying within 30-50 yards of the coast. Depths in this area range from 5 feet in closer coves to 15-20 feet further out. The underwater landscape consists mainly of rocky structures with patches of coral. You are likely to see various reef fish, including Yellow Tang, Parrotfish, and Convict Tang. Sea turtles (honu) are commonly sighted, often feeding in shallower areas (5-10 feet deep) close to the rocky edges, particularly in the mornings. You might also spot Moorish Idols. To enhance your underwater viewing experience, consider bringing quality kids snorkels. Keep a consistent lookout for small boats entering and exiting Honokohau Harbor, especially if swimming towards the harbor entrance. If you’re interested in other unique Big Island marine encounters, consider snorkeling with manta rays on the Big Island.

Amenities and Shelter

Restrooms are located at the Kaloko-Honokōhau National Historical Park visitor center, a short drive from the harbor entry. Portable facilities may be available closer to the harbor entrance; check upon arrival. There are no dedicated freshwater showers directly at the snorkeling access points. Expect limited natural tree cover directly at the entry areas. Any available shade from sparse kiawe trees is usually gone by 11 AM, giving way to full sun.

Pro Tip: If Honokohau’s rocky entry is too difficult for your children on a given day, Kahalu‘u Beach Park, located approximately 10 minutes south, offers a sandier, shallower entry and generally calmer conditions suitable for beginners.

Essentials for a Good Trip

• Reef shoes: The entry is over sharp lava rock and uneven ground; standard sandals will not protect feet adequately.
• Rash guard: Essential for sun protection given the limited natural shade and to prevent scrapes from incidental contact with rocky edges.
• Swim buoy/safety noodle: Provides extra visibility for kids and assists with flotation in variable water conditions. Consider reviewing best kids inflatable snorkel vests for added safety.
• Reusable water bottle: No freshwater access directly at the beach; staying hydrated is important under the Big Island sun.
• Small dry bag: To keep car keys, phones, and other small items safe from splashes near the entry or during the walk.
