What Chinaman's Hat Offers Anglers
Chinaman's Hat—officially Mokolii Island—sits about a half-mile off the windward coast of Oahu near Kailua, and it holds some of the most accessible saltwater fishing in Honolulu County. The shallow waters surrounding the islet hold reef fish, jacks, and occasional larger species that cruise the deeper channels nearby. You can fish from shore on the Kailua side, wade out to the island at low tide, or launch a small boat to work the deeper water on the seaward side.
The island itself is a distinctive cone-shaped volcanic remnant that rises about 206 feet and is visible from the Kailua Beach shoreline. Most anglers fish the shallow flats and reef edges rather than the island itself, which is a seabird sanctuary with restricted access. The real draw is the combination of easy access, calm leeward conditions most days, and the variety of fish that move through the area with the tides.
Key Takeaways
- Chinaman's Hat is best fished from Kailua Beach or by wading the shallow flats on the windward side, where reef fish and jacks are most common.
- Low tide allows you to wade out toward the island, but the seabird sanctuary designation means you cannot land on the island itself.
- The shallow flats hold bonefish and permit in winter months, while summer brings more reef species and the occasional trevally.
- Bring polarized sunglasses, wade shoes with good grip, and light tackle—most fish here run under five pounds, though jacks can exceed ten.
- Conditions are calmest in the morning and during settled weather; trade winds can chop the water by afternoon.
How to Reach Chinaman's Hat from Kailua Beach
Park at Kailua Beach Park on the windward side of Oahu. The main lot fills quickly on weekends, so arrive early or use the overflow parking further down Kailua Road. From the parking area, walk north along the beach toward the distinctive cone-shaped island—you cannot miss it. The walk takes about ten to fifteen minutes depending on where you park.
Once you reach the northern end of Kailua Beach, you are at the launch point for wading. The shallow flats extend from shore toward Mokolii Island, and at low tide the water depth stays under three feet for most of the distance. If you have a small boat or kayak, you can launch from the beach here as well, though launching through the surf requires care and timing.
Tides, Depth, and Bottom Conditions
The flats around Chinaman's Hat are sand and coral rubble, with scattered patches of seagrass. Water depth ranges from ankle-deep at the shoreline to about eight feet at the deepest channels between the island and the main reef. Low tide exposes more sand and makes wading easier, but it also concentrates fish into deeper pockets, so you have to work harder to find them.
High tide pushes fish onto the flats and into the shallows, making them easier to spot and reach, but it also covers the sand bars and makes navigation less certain. Most anglers prefer the hour or two before and after low tide, when the flats are exposed enough to wade safely but deep enough to hold feeding fish. Tides in Honolulu County shift about fifty minutes later each day, so check a tide table before you go.
The seaward side of the island drops off more steeply into deeper water where larger jacks and occasional snappers hold. This side is best fished from a boat or by casting from the island itself—but remember that landing on Mokolii is restricted to protect nesting seabirds.
Fish Species and Seasonal Patterns
Bonefish and permit move through the flats in winter (November through March), though they are not as abundant here as on the south shore. You will see them cruising the deeper channels and the edges of the seagrass beds, especially on calm mornings. They are spooky and require a long cast and a quiet approach—polarized sunglasses are essential for spotting them.
Year-round residents include small reef fish (goatfish, wrasses, parrotfish) and jacks. The jacks—mostly bluefin trevally and giant trevally—are the most exciting target. They hunt in loose schools and will chase small baitfish into the shallows. Summer months (June through September) bring more jacks and more consistent reef activity, though the trade winds can make conditions choppy by afternoon.
Mullet and small mackerel are present most of the year and make good bait for bottom fishing or for chumming to attract larger fish. The channels on the seaward side occasionally hold snappers and groupers, especially in deeper water beyond the immediate flats.
Tackle and Technique for the Flats
Light spinning tackle works well for most flats fishing here. A six to seven-foot rod with a smooth drag and a reel spooled with eight to ten-pound braided line gives you the sensitivity to feel small bites and the strength to handle a jack if one appears. Fluorocarbon leaders of twelve to fifteen-pound test reduce visibility in the clear water.
Small soft plastics (two to three inches) in natural colors—white, tan, or pale green—work for jacks and reef fish. Cast ahead of cruising fish and retrieve with a slow, steady pace or with short twitches to imitate wounded baitfish. For bonefish and permit, use small shrimp patterns or bonefish flies if you have a light fly rod. Wade slowly and scan the water constantly with polarized glasses—you are hunting by sight, not by feel.
If you are bottom fishing from a boat or from the deeper channels, use small hooks (size 2 to 1/0) baited with mullet or shrimp. The fish here are not large, so heavy tackle is unnecessary and will actually reduce your catch rate.
Safety and Practical Considerations
Wear reef shoes or wading boots with good grip—the coral and rock are sharp, and the bottom can be slippery. The sun reflects intensely off the water and sand, so bring sunscreen and reapply often. Drink more water than you think you need; the windward side can feel cooler than the south shore, but you are still in the tropics.
Trade winds typically pick up in the afternoon, so plan to fish in the morning when the water is calmer and visibility is better. Check the weather forecast before you go—sudden squalls can move in quickly on the windward side. If you are wading, keep an eye on the horizon and be ready to head back to shore if conditions deteriorate.
The seabird sanctuary designation means you cannot land on Mokolii Island itself. Respect the closure—the island is home to nesting seabirds, and landing disturbs them. Fish the flats and channels around the island instead.
Frequently Asked Questions
Can I fish Chinaman's Hat year-round?
Yes. Winter months (November through March) bring bonefish and permit, while summer (June through September) offers more consistent jacks and reef fish. Spring and fall are transitional but still fishable. Trade winds are typically lighter in winter, making conditions more pleasant for wading.
Do I need a boat to fish here?
No. Most of the productive water can be reached by wading from Kailua Beach. A small boat or kayak lets you reach deeper channels and the seaward side of the island, but it is not necessary for good fishing on the flats.
What size fish should I expect?
Most reef fish run one to three pounds. Jacks typically range from three to eight pounds, though larger ones over ten pounds show up occasionally. Bonefish and permit, when present, usually run two to five pounds. This is not a destination for trophy fish, but the action can be steady and fun.
Is there a fee to fish at Kailua Beach?
Kailua Beach Park is free to enter. Parking is free as well, though the main lot fills quickly on weekends. Arrive early or use the overflow parking on Kailua Road.
What time of day is best for fishing?
Early morning is best—the water is calmer, the light is better for spotting fish, and trade winds have not yet picked up. Fish from sunrise through mid-morning, then consider heading out if afternoon winds become strong.
