Not the water colour. Entry, lifeguards, shade, parking and how fast you can leave when a child is done.
Which beach is the prettiest is our best beaches on Maui guide; the wider family planning is our Maui with kids guide. This page is the logistics.
Three guarded beaches in a row, which exists nowhere else on the island.
Kamaʻole I, II and III all have lifeguards and bathrooms. That is the fact that should decide a Kīhei family beach morning before anything else does.

Kamaʻole II is the straightforward swim-and-sand morning. Kamaʻole III has the most parking and the most shade, plus grass and room to move when the kids need a break from the sand — which is why it is the one to pick with young children.
The deciding fact is parking. Kamaʻole II has street parking only and no lot at all, and with a family and a car full of gear that is the difference between an easy morning and a hot walk carrying everything.
The Kamaʻole lots open at 7 a.m. and close at 8 p.m. PARK MAUI applies at the paved Kamaʻole I and III lots, so budget for it or use Kam II's street parking. Do not overthink the choice if you are staying across the road from one of them: a calm beach you can walk to beats loading the family into the car for a marginally better one.
The best mixed-age beach in South Maui, with one thing missing.
Keawakapu is long enough for adults to walk, has plenty of sand for children and sits between Kīhei and Wailea. It has no lifeguard, so use it differently from the Kamaʻole parks — closer in, and with an adult in the water rather than on the towel.
The resort-family advantage is that the day does not need a second drive.
Ulua and Mōkapu are the useful pair for older kids who want to try snorkelling: an approachable entry in calm water and reef close enough that nobody has to swim offshore. Neither has a lifeguard. Wailea Beach and Polo sit in the same strip and all of them stitch into breakfast, a pool reset, lunch or the Wailea Beach Path without creating another driving day.

One beginner bay, one relaxed bay, and one that wins on convenience alone.
Kapalua Bay is our favourite place for a child's first real snorkel on a calm morning. Nāpili is the other relaxed family bay. Kāʻanapali wins on pure convenience, because pools, restaurants and the beach walk are all in one place — which matters more with young children than the beach itself does.

Two beaches worth knowing properly rather than simply avoiding.
Big Beach is gorgeous and has two lifeguards, which is more than almost anywhere in South Maui. It is still not our young-child swimming default, and the reason is the shorebreak rather than any absence of supervision — it can be severe, and it breaks directly onto sand.
D.T. Fleming is lifeguarded and has the best facilities of any West Maui beach, and it can also be rough. Both things are true, and a parent should have both before deciding. Exposed North Shore beaches deserve the same caution. A child seeing other people in the water is not evidence that the water suits that child.
Keep young children within arm's reach in the ocean. Not within sight — within reach.
Use a lifeguarded beach when you have the choice. On this island that usually means one of the Kamaʻole parks.
Go earlier. The water is calmer, the parking is easier and nobody has melted down yet.
Bring dry clothes and snacks for the car. A beach morning ending well is mostly about the ten minutes after it.
Check the lot before you load the car. Kamaʻole II has no lot at all and PARK MAUI applies at Kam I and III.
Kamaʻole III, for most families. It has the most parking and the most shade, while Kamaʻole II has street parking only and no lot.
Yes, all three, along with bathrooms. That is the strongest run of guarded beaches anywhere on Maui.
No. It is protected relative to most West Maui beaches, but winter swell and changing conditions still matter.
It has two lifeguards, which is more than most of South Maui, and it is still not our default young-child swim beach. The shorebreak is the reason.
No. It is an excellent mixed-age beach, but supervise it yourself rather than treating it like the Kamaʻole parks.
D.T. Fleming, which is also lifeguarded. It can be rough, so check conditions rather than assuming facilities mean calm water.
