Best Snorkeling on the Big Island

The best snorkeling on the Big Island is found at Kahaluu Beach Park for calm water and sea turtles, Two Step at Honaunau Bay, Kaawaloa Cove in Kealakekua Bay, the Kona manta ray night snorkel, and the sheltered bays and coves of the Kohala Coast. Each one suits a different kind of day, from ten minutes of wading in before breakfast to an evening on the water after sunset. Here is how to choose, what to bring, and how to leave the reef exactly as you found it.

Kahaluu Beach Park: calm water and honu for beginners

Kahaluu Beach Park sits on Alii Drive in Keauhou, just south of Kailua-Kona, and it is the easiest place on the island to begin. A lava-rock reef arc shelters a calm, shallow inner bay, so the water stays gentle enough for first-timers and children. Green sea turtles, the honu, feed here very often, and you can float nearby without leaving the shallows. The volunteer Reef Teach program, run from the Kahaluu Bay Education Center, places docents on the beach at peak hours to point out the marine life you are looking at. The park has a lifeguard, restrooms and parking, which keeps the whole morning simple.

Two Step at Honaunau Bay: a lava-rock entry beside a national park

Two Step at Honaunau Bay is about 20 minutes south of Kailua-Kona, beside Puuhonua o Honaunau National Historical Park. It takes its name from two natural lava-rock steps that lead into the water, which gives you a clean place to enter. Near shore the coral is shallow, and the bottom drops much deeper in the middle of the bay, so the view changes as you swim out. Snorkeling is not allowed inside the park itself at Keoneele Cove, and Two Step is the access just outside it. Roadside parking fills early, so arrive in the morning, when the water is also usually at its calmest.

Kealakekua Bay and the Captain Cook Monument

Kealakekua Bay State Historical Park holds some of the clearest water on the coast, and the place to be in it is Kaawaloa Cove, at the Captain Cook Monument. You can reach the cove four ways: a boat tour, a guided kayak tour with a state-permitted operator, a rental kayak that carries a valid State Parks permit (ask the rental company to confirm), or a steep hike of roughly 3.8 miles round trip with about 1,300 feet of climb on the way back up. Taking or harming marine life, altering coral, and feeding fish are all prohibited here. Weigh the effort honestly before you set out.

The Kona manta ray night snorkel

Boats leave at sunset, from areas such as Keauhou Bay or Honokohau Harbor, for known reef manta feeding sites. Once you are in the water, you hold a lit float board. The light attracts plankton, and the plankton draws the mantas to the surface near you. You stay at the surface and never dive down to or touch a manta. The Kona manta ray night snorkel is available by tour only, so there is no shore-entry version. KBM's concierge can arrange it, and because high-demand tours can book up, ask early. Each tour vendor sets its own cancellation window.

Kohala Coast bays, plus gear, sunscreen and reef etiquette

Near KBM's Waikoloa and Mauna Lani homes, Anaehoomalu Bay (A-Bay) fronts Waikoloa Beach Resort with calm water and snorkeling near the rocky points at each end. Coves near Mauna Lani and the Puako area offer shore-entry snorkeling with a chance of turtles. Conditions vary with swell, so check each morning. Snorkel gear and boogie boards are not provided in KBM units, unless a set was left from a prior stay. Most units include a beach package, and KBM's concierge can point you to a nearby rental shop or arrange a guided tour. Use mineral sunscreen, never touch coral or honu, and give wildlife room.

Ocean conditions, tour schedules, access rules and permit requirements change. Check current surf and ocean conditions each morning before you get in the water, and confirm current-year details with your tour operator or rental company before you travel.

Frequently Asked Questions

What is the best snorkeling spot on the Big Island for beginners and kids?

Kahaluu Beach Park in Keauhou is the easiest start. A lava-rock reef arc shelters a calm, shallow inner bay, green sea turtles feed there very often, and the park has a lifeguard, restrooms and parking. Reef Teach volunteers are on the beach at peak hours to help you identify what you see.

Can you snorkel at Captain Cook without a boat?

Yes, but not casually. You can hike roughly 3.8 miles round trip to Kaawaloa Cove, with about 1,300 feet of climb on the way back up. Otherwise, go by boat tour, a guided kayak tour with a state-permitted operator, or a rental kayak carrying a valid State Parks permit.

Do KBM rentals include snorkel gear?

No. Snorkel gear and boogie boards are not provided in KBM units, unless a set happens to have been left from a prior stay. Most units include a beach package with towels, umbrella, chairs and a cooler. KBM's concierge can point you to a nearby rental shop or arrange a guided snorkel tour.
