Learn how to build impressive sandcastles with the Alto stackable sand toy. This guide covers tips for kids and parents to create sturdy towers and castles at the beach.

Quick answer

Use the Alto's three stackable components to build sturdy towers and castles. Start with damp sand, pack each layer firmly, and stack from largest to smallest for a stable structure.

Why stacking from largest to smallest works best

The Alto's three stackable components—small, medium, and large—are designed to nest together. Starting with the largest base gives you a wide, stable foundation that prevents toppling. Adding the medium and small layers on top creates a classic tower shape that holds up better against wind and waves.

The right sand consistency matters

Dry sand won't hold its shape, even with a good mold. Damp sand—where you can squeeze a handful and it keeps its form—is ideal. If the sand is too wet, let it drain for a minute before packing it into the Alto. Too dry? Add a little water from your bucket and mix.

Step-by-step sandcastle building with the Alto

1. Prepare your sand: Find a spot with damp sand near the waterline. Scoop sand into your bucket and add a little water if it's dry. Mix until it holds together when squeezed. Check that a handful of sand keeps its shape before you start stacking.
2. Pack the largest mold firmly: Fill the large Alto component with damp sand. Press down firmly with your hands to eliminate air pockets. Turn it over and tap the bottom to release the shape. If the sand crumbles, it's too dry—add water and repack.
3. Stack the medium layer: Place the medium Alto component on top of the large sand block. Fill it with damp sand, pack it down, and carefully lift the mold. The weight of the sand helps it stick. Center the medium mold directly over the base to avoid a lopsided tower.
4. Add the small top: Repeat the process with the small component on top. For a castle look, use the small mold to create a turret or decorative top piece. Don't rush—allow a few seconds for each layer to settle before lifting the mold.
5. Decorate and reinforce: Use your hands or a small shovel to carve windows, doors, or a moat around the base. The Alto components can also be used as separate molds for walls or smaller towers. A shallow moat helps protect the base from incoming waves.
