Igloo Den

On a Steep Shingle Beach

A carved dome hideout, built up rather than dug down — adapted for steep shingle beach conditions.

About This Hole

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.

About This Beach

Pebble and shingle beaches slope sharply into the sea. While you can't dig a traditional sand hole, the loose stones allow for brilliant channel, dam, and moat building above the tideline where any small amount of sand collects. Think construction more than excavation.

Compatibility

Possible but challenging — work with the beach's natural conditions and scale your ambitions accordingly.

Safety — Beach: Steep gradient makes it easy to slip into the sea. Keep younger children well back from the water's edge.
Safety — Digging: Never leave a deep hole unattended. Fill it in before leaving the beach. Keep walls sloped, not vertical.

What You'll Need

  • spade
  • bucket
  • trowel

Ages: 4 and up (adults recommended for the hollowing stage)  |  Time: 60–90 minutes

How to Dig It — Steep Shingle Beach Edition

Conditions on this beach: Pebbles, cobbles, and coarse gravel — with pockets of coarse sand in hollows. Steep gradient means tides arrive fast. Always stay aware of incoming waves.
  1. 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.
  2. Wet the mound thoroughly and let it settle for a few minutes — this compacts it further and makes hollowing safer.
  3. Mark a small entrance at the base, no more than 30–35cm wide, and begin hollowing inward and slightly upward.
  4. Work slowly, removing small amounts of sand at a time and pressing the emerging ceiling with your hand to check it feels firm.
  5. Widen the interior gradually once the roof feels solid, keeping the walls thick — at least 15–20cm — for stability.
  6. Smooth the interior walls and entrance, and add a small shelf or 'window' opening near the top if the structure allows it.
  7. 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 for Steep Shingle Beach

Spring

Good compacting conditions — the mound holds its shape well.

On this beach in spring: Stones shift and collapse more than sand. Hands and knees take a beating — gloves recommended. True hole digging is limited to sandy pockets.

Summer

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

On this beach in summer: Stones shift and collapse more than sand. Hands and knees take a beating — gloves recommended. True hole digging is limited to sandy pockets.

Autumn

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

On this beach in autumn: Stones shift and collapse more than sand. Hands and knees take a beating — gloves recommended. True hole digging is limited to sandy pockets.

Winter

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

On this beach in winter: Stones shift and collapse more than sand. Hands and knees take a beating — gloves recommended. True hole digging is limited to sandy pockets.
