Treasure Hole
On a Tidal Flat Beach
Dig deep, hide well, find glory — adapted for tidal flat 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
At low tide, tidal flats expose enormous areas of firm, wet sand or silt stretching hundreds of metres from the high-water mark. This gives you hours of digging at low tide with the bonus of watching the sea slowly reclaim your work. Common around estuaries and sheltered bays.

How to Dig It — Tidal Flat Beach Edition
- Collect your treasure — shells, pebbles, small toys, wrapped sweets.
- Choose your spot and pace out a route from a landmark (rock, towel, windbreak).
- Draw a rough map while someone else digs.
- Dig 40–60cm down, drop in the treasure wrapped in a bag or cloth.
- Fill in and tamp down. Mark with a stick or shell. Hand over the map.
- 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.
