Igloo Den

A carved dome hideout, built up rather than dug down

Where the Foxhole is dug into flat ground, the Igloo Den is built the opposite way: a large mound is piled up first, then carefully hollowed out from a small entrance to create a dome-shaped shelter you can sit inside. It takes longer than a foxhole and needs more patience with the hollowing stage, but the result is a genuinely impressive structure that stands well above the sand around it rather than hiding below it.

When to Dig It

🌱 Spring ☀️ Summer 🍂 Autumn ❄️ Winter

Best Conditions

Damp, well-compacted sand is essential — this project relies on the mound holding its shape while hollow, which dry sand simply won't do. Build well away from the tide line with plenty of space around the mound.

Safety note: Always fill in holes before leaving the beach. Never leave a deep open hole unattended.

How to Dig It

Pile up a large mound of sand, at least a metre high and wide, packing each layer down firmly with the back of a spade as you go.
Wet the mound thoroughly and let it settle for a few minutes — this compacts it further and makes hollowing safer.
Mark a small entrance at the base, no more than 30–35cm wide, and begin hollowing inward and slightly upward.
Work slowly, removing small amounts of sand at a time and pressing the emerging ceiling with your hand to check it feels firm.
Widen the interior gradually once the roof feels solid, keeping the walls thick — at least 15–20cm — for stability.
Smooth the interior walls and entrance, and add a small shelf or 'window' opening near the top if the structure allows it.
As with tunnels, an adult should always check the roof integrity before children go inside, and it should never be left as an unattended structure once complete.

Variations

For a simpler version, build the mound smaller and only hollow out a shallow seat rather than a full interior. For an ambitious version, connect two mounds with a short dug passage between them.

Seasonal Tips

Spring

Good compacting conditions — the mound holds its shape well.

Summer

Wet the mound generously before hollowing, as dry summer sand won't hold a dome shape on its own.

Autumn

Naturally damp sand makes this one of the easier seasons for a clean hollow.

Winter

Cold wet sand compacts extremely well, though the build stage takes longer with cold hands — pace the work.
