What do kids love about being at a beach? If you answered “putting sand on anything and everything they come in contact with”, then you would be correct. They don’t understand that it’s the duty of the parents to deal with sand in all of the towels, clothing, and shoes in the aftermath.
If you want to have fun with with children at a beach without having to dread the cleanup afterwards, the Four Person Beach Mat will be a thing of pure beauty. This is a much larger version of the sandless beach mat, and it was originally made for military use. It literally can’t be covered in sand. There are two layers of woven polyurethane that the sand will fall through as if it were water. Speaking of, it will keep dirt, dust, and H2O from sitting on the surface. It’s ten square feet, and has metal D-rings on each corner so you can pin it down if you’d like. It costs $100, and won’t mold or mildew.
