The question we get most from families is not which beach is prettiest. It is where to take a small child who is not confident in the water yet. Somewhere with no waves, somewhere they can stand up everywhere, somewhere a parent can relax for twenty minutes.
That list is shorter than you would hope. Most of this coastline is lava, which is beautiful, dramatic and for a four year old completely useless. The beaches that genuinely work are specific places spread across sixty miles of coast, and the right one depends far more on how your child is in water than on anything else.
We host families all year, so here is the list we actually hand them, with the honest warnings attached.
If your child is not swimming confidently yet, start here
Three places, in order, and you can stop reading after this section if you like.
Spencer Beach Park near Kawaihae. The flattest water on this side of the island, a gentle sandy slope, real shade, and lifeguards at weekends. This is the one for a two or three year old.
ʻAnaehoʻomalu Bay at Waikoloa. Sand entry, no rock, and a bottom that slopes so gradually a child can stand a long way out. No lifeguard, so stay within arm’s reach.
Wawaloli Beach Park by the airport. Not a swimming beach at all, but a lava shelf traps a big shallow pool with no waves in it, which is exactly right for a child who wants to sit down in warm water and not be knocked over.
Everything below adds detail, other ages, and the places to be careful about.
If you are staying in South Kona, start with the honest answer
There is no great toddler beach in Kealakekua or Captain Cook. We would rather say that plainly than send you somewhere that disappoints.
The closest real sand is Hoʻokena Beach Park, about twenty miles south of Kailua-Kona and a short run down the hill from us. The sand is a dark steel grey, a blend of black and white grains, and it gets genuinely hot underfoot, so bring something for small feet. Swimming is best at the south end where the bottom is sandier. There is a concession stand with food, drinks and ice, plus showers, restrooms and picnic tables, which is more than most beaches on this coast offer.
Two Step at Honaunau, which everyone will tell you about, is not a toddler beach. The entry is a lava ledge you step off into deep water. It is superb for confident swimmers and wrong for little ones. Its neighbor, Puʻuhonua o Hōnaunau, the place of refuge, is the better family stop down there. The path is flat and shaded, turtles are usually asleep on the little beach, and most families plan an hour and stay two.
For a proper beach day with young kids, you drive north. It is worth it.
Kahaluʻu Beach Park, the best all rounder
If you only take one recommendation from this page, take this one. Kahaluʻu sits just south of Kailua-Kona in Keauhou, roughly twenty five minutes from us and ten from town.
It is shallow, it is protected by an old breakwater, and it is absolutely full of reef fish. Green sea turtles come in to feed and rest most days. A six year old with a mask can count twenty species in ten minutes standing in water that reaches their waist, and that is a better morning than any waterslide delivers. There are restrooms, showers and a lifeguard.
Three honest notes. The bottom is rock and coral rubble, not sand, so water shoes are not optional. It gets busy, so arrive early. And there is a current that runs out through the gap in the breakwater at the north end, which the lifeguards will point out if you ask, so keep small children on the shoreward side.
Give the turtles room. They are protected by law and the required distance is further than people assume.
Wawaloli Beach Park, the beach by the airport
About seven miles north of downtown Kailua-Kona, right beside the runway, which means you will watch planes come in low over the water while your kids play. That alone sells it to a certain age group.
The reason it works is a flat pāhoehoe lava shelf running out from the shoreline, which traps a large shallow pool and a set of tide pools behind it. Toddlers can sit down in warm knee deep water with no waves at all. There is a small sandy area, plus restrooms, showers, picnic tables and barbecue grills, so it holds up for a full afternoon.
The warning matters here. The protected pool is calm, but the open ocean immediately beyond it is not a swimming beach, and people have been swept off the rocks in high surf. Stay in the pool, keep off the wet rock at the edge, and wear water shoes, because the lava is sharp and slippery.
Old Kona Airport, the keiki ponds in town
Confusingly, the island has a second airport beach. The old Kona airport runway is now a state park in Kailua-Kona, and along its shoreline sit a set of shallow tide pools that families have used for generations.
Park near the first yellow gate and look for the lone palm. The pools there are deep enough to sit in and full of minnows, tiny shrimp and shells, which occupies small children for an hour at no cost. Time it for a rising tide rather than dead low, and bring your own shade, because there is very little. There is also a playground and a long flat stretch of old runway that is very good for scooters and bikes.
ʻAnaehoʻomalu Bay at Waikoloa
Known to everybody as A Bay, and the best straightforward sandy beach for young children on this side of the island.
The entry is sand rather than rock and the bottom slopes very gently, so a child can stand a long way out. A reef offshore keeps it calm. Behind the beach sit two ancient Hawaiian fishponds, Kuʻualiʻi and Kahapapa, and one translation of the name is bay of the protected mullet, which is what was raised in them. There is a palm grove for shade, restrooms, showers and free parking a couple of minutes from the sand.
Two things to know. There is no lifeguard, so this is an arm’s reach beach with toddlers. And the wind picks up in the afternoon, which is why the kite surfers show up, so mornings are calmer. Snorkeling here is often murky, so come for the swimming rather than the fish.
It is about forty minutes north of Kailua-Kona and closer to an hour from Kealakekua, so plan a day rather than an afternoon. If you are already going up that way, our guide to the best pools for kids on the Big Island covers the resort pools in the same area and how to buy a day pass into them.
Spencer Beach Park, the best one for toddlers
Further north again, near Kawaihae, and worth the drive once. An offshore reef plus the harbor breakwater keep the water almost completely flat, the sand slopes gently, and there is real shade from mature trees, which is rarer than it should be on this island.
Lifeguards are on duty at weekends and holidays. There are restrooms, showers, picnic tables and grassy areas, and you can camp with a permit. Water shoes again, because there is reef underfoot in places.
This is the one we name when somebody asks for the calmest water on the island for a two year old.
Kūkiʻo, if you want quiet
About five miles north of the airport, with a shallow lagoon that suits toddlers and unusually clean restrooms. Two catches. There is a drop off at the end of the lagoon, so it needs supervision. And public parking is limited to twenty seven spaces with a security check in, so go early or do not bother.
Two to be careful about
Magic Sands, also called Laʻaloa. The small sandy area at the north end looks like a natural paddling pool and children are drawn to it, but the main beach has a serious shore break that injures adults every year. The sand itself washes away in winter swell and comes back later. Beautiful beach, bad choice with small kids.
Hapuna and Kua Bay. Both are stunning and both are better suited to strong swimmers and older children. In winter especially they get real surf and currents. Save them for a calm summer morning, and check conditions before anyone gets in.
What to bring
Water shoes for every person, because almost every good spot on this list has rock or reef underfoot. Rash guards, which beat reapplying sunscreen to a wriggling child every ninety minutes. Reef safe sunscreen, which is the law here. Your own shade, since only a few of these have trees. And snacks, because only Hoʻokena has anywhere to buy them.
Frequently asked questions
What is the best beach for toddlers on the Big Island?
Spencer Beach Park near Kawaihae for the calmest water and the best shade, or ʻAnaehoʻomalu Bay at Waikoloa for the easiest sandy entry. Closer to Kona, the shallow pool at Wawaloli Beach Park works well.
Which beach is best for kids who want to snorkel?
Kahaluʻu Beach Park, without question. Shallow, protected, lifeguarded and full of reef fish and turtles.
Is there a good beach for children near Kealakekua?
Not really, and we would rather be honest about it. Hoʻokena is the closest real sand, and Kahaluʻu is about twenty five minutes north and worth the drive.
Are there lifeguards at Big Island beaches?
At some, not most. Kahaluʻu has one, and Spencer has them at weekends and holidays. A Bay, Wawaloli and the tide pool spots do not, so stay within arm’s reach of small children.
Do you need water shoes?
Yes. This is a young volcanic island and most of the shoreline is lava rock or reef. Water shoes are the single most useful thing you can pack for a family trip here.
Our wider guide to the beaches near Kona covers the same coast for adults and stronger swimmers, and our Big Island with kids itinerary puts these into a workable week. If you need somewhere with space for everyone at the end of a beach day, here is what we have learned about what families need from a Kona rental, or come and ask us directly.
