Den or Foxhole

On a Shell Beach

Excavate a hideout and disappear — adapted for shell beach conditions.

About This Hole

A wide, comfortable sitting hole — deep enough that a child sitting in it is at ground level or below. It becomes their base, their den, their headquarters. Can be expanded into a two or three-person dugout with bench seats carved into the walls. One of the most satisfying holes to actually inhabit.

About This Beach

Beaches composed primarily of broken shells — common on sheltered bays and lagoons where wave energy is low enough for shells to accumulate. The shell fragments pack together well and can hold shapes surprisingly effectively, though the edges can be sharp. A novelty digging experience with built-in treasure (whole shells uncovered as you dig).

Compatibility

Good match — shell beaches provide solid conditions for this hole type with a little preparation.

How to Dig It — Shell Beach Edition

Conditions on this beach: Crushed and whole shells, often mixed with coarse sand beneath the surface layer. Usually found on sheltered, low-energy coastlines with modest tidal ranges.
  1. Choose a spot well above the high tide mark.
  2. Mark out a rectangle roughly 1m x 80cm (larger for multiple children).
  3. Dig down steadily, throwing all spoil forward to build a windbreak wall.
  4. When 40–50cm deep, start carving bench seats into the long walls.
  5. Round off the base so it's comfortable to sit in.
  6. Decorate the windbreak wall — shells pressed in, a flag on a stick.

Variations: Extend to a trench for multiple children. Add a connecting tunnel to an adjacent hole. Cover the top with a towel weighted by spades for a fully enclosed den.

Seasonal Tips for Shell Beach

Good conditions. Aim for a south-facing spot to catch spring sun down in the hole.
