Get a folding beach wagon, not a cart.

Yes, they exist — look for a folding utility wagon, not a traditional beach cart.

Most beach carts either fold awkwardly or are too small. Folding wagons (the kind with a collapsible frame and pull handle) fold flat enough to slide behind a seat or into a trunk. They’ve got bigger wheels that actually roll on sand, and they can handle a 48-quart cooler plus two chairs without tipping.

The trick is to check the folded dimensions before buying. Many list “folds flat” but still end up three feet long. Aim for one that folds under 30 inches in at least one dimension. Brands like Mac Sports or Radio Flyer make reliable ones under $100.

Don’t spend more unless you’re hauling for a crowd.
