The verdict

The waterfall slide is what got me: you drop a boat in at the top, pull a lever, and the fall opens up so the boat slides straight through into the pool.

That one clever function does more to make this feel alive than a whole page of stickered detail ever could. It is priced fairly for what you get and it plays wonderfully. If you want an intricate adult display build, this is not your set, and that is completely fine.

Best for: Kids 8 and up who want a water park they can actually run play scenarios through, not just look at.

The full review

What it is

I have a soft spot for a good water park set, and Heartlake City Water Park earns it in the way that matters most for this theme: the play functions actually work and they are fun. Three slides anchor the whole thing, and each one does something different. The corkscrew twists, the spiral tube slide uses those lovely trans-bright-green curved tube pieces, and the waterfall slide is the showpiece. You climb a minidoll into a boat, pull a lever, and the waterfall itself splits open so the boat slides through and lands in the pool below. The first time I worked that lever I grinned, because it is the sort of mechanism that turns a static model into a toy a kid will replay a hundred times.

The catch

I will be straight with you about the value question, because it is the honest caveat here. At 79.99 dollars for 825 pieces, the price per part is fine, but a chunk of those parts are the big slide molds and the plates that make up an open pool deck. That means the model reads as airy and spread out rather than densely detailed, and the build itself is friendly and simple. If you are eight, that is exactly right. If you are an adult builder hoping for engineering to chew on, you will breeze through it and probably wish there was more to sink your teeth into. It also looks a little modest in photos next to the sprawling older Heartlake water parks, so temper the expectations there.

Who it's for

This one is easy to place. If you or the kid in your life loves imaginative, run-the-scenario play, where the whirlpool spins and the boat launches and everyone queues for the slides, this delivers day after day and the price is reasonable for that. The extra detail spots (shower, lockers, restroom, snack stand) keep the stories going. I would also flag the character lineup as a quiet highlight worth mentioning to anyone who cares about representation. If your heart is set on an elaborate showpiece for a shelf, though, look elsewhere in the lineup, because this set is built to be played with, not admired from a distance.

The parts story

What the build is actually like, and the pieces worth knowing about.

Building this is a relaxed, breezy afternoon rather than a challenge, which suits the theme perfectly. You put together the slide towers, lay in the pool deck, and add the little amenity stations, and the assembly stays approachable the whole way through. The satisfying moments come from the mechanisms rather than the techniques: getting the waterfall lever to trip cleanly, and slotting the trans-bright-green tube sections together so a minidoll can actually shoot down them. It is the kind of build where the fun is front-loaded into the finished functions rather than earned through fiddly steps.

For parts hunters there are a few recolors worth knowing about. The curved and straight trans-bright-green slide tubes are recolors of molds that first appeared back in the 2020 Summer Fun Water Park, so if you want that translucent green for a MOC waterfall or a sci-fi tube, this is a friendly source. There is also a Plate Special 2 x 8 with Door Rail in blue, a 2 x 14 plate in medium nougat, and a Fence Lattice 1 x 4 x 2 in coral, all handy everyday elements in colors you do not trip over often. Nothing here is a grail piece, but it is a nice little bag of useful recolors alongside a genuinely fun toy.
