Igloo Den

On a Sheltered Cove

A carved dome hideout, built up rather than dug down — adapted for sheltered cove 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

Small, enclosed beaches sheltered by headlands or cliffs. The calm water and shelter from wind means sand stays damp and workable for longer. Often backed by cliffs that provide shade. The intimate scale makes these ideal for family sessions — natural rock walls frame your digging area.

Compatibility

Good match — sheltered covees provide solid conditions for this hole type with a little preparation.

Safety — Beach: Check cliff stability before sitting near the base. Tides can cut off exits in enclosed coves — know your escape route and always check tide times.
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 — Sheltered Cove Edition

Conditions on this beach: Medium to coarse sand, often mixed with small pebbles near the cliff base. Sheltered from swell but tidal range still applies. The small size of the beach means tides can cut you off — always check times.
  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 Sheltered Cove

Spring

Good compacting conditions — the mound holds its shape well.

On this beach in spring: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.

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: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.

Autumn

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

On this beach in autumn: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.

Winter

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

On this beach in winter: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.
