Treasure Hole

On a Shell Beach

Dig deep, hide well, find glory — adapted for shell beach conditions.

About This Hole

A deep, narrow hole dug for the purpose of burying treasure — shells, pebbles, toy coins — and then finding it again. The game is in the ritual: marking the spot, pacing out the steps, drawing a map. Perfect for children aged 5 and up who can grasp the concept of a secret.

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. Collect your treasure — shells, pebbles, small toys, wrapped sweets.
  2. Choose your spot and pace out a route from a landmark (rock, towel, windbreak).
  3. Draw a rough map while someone else digs.
  4. Dig 40–60cm down, drop in the treasure wrapped in a bag or cloth.
  5. Fill in and tamp down. Mark with a stick or shell. Hand over the map.
  6. Watch the kids try to find it — intervene only if they're really lost.

Variations: For younger children, bury it shallowly and make the map simple. For older children, set multiple decoy spots. A clue trail leading to the map adds another layer.
