Den or Foxhole
On a Tidal Flat Beach
Excavate a hideout and disappear — adapted for tidal flat 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
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
- Choose a spot well above the high tide mark.
- Mark out a rectangle roughly 1m x 80cm (larger for multiple children).
- Dig down steadily, throwing all spoil forward to build a windbreak wall.
- When 40–50cm deep, start carving bench seats into the long walls.
- Round off the base so it's comfortable to sit in.
- 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 Tidal Flat Beach
Spring
Good conditions. Aim for a south-facing spot to catch spring sun down in the hole.
On this beach in spring: Soft mud patches can be surprisingly deep. Time pressure from rising tide creates natural excitement (and urgency).
Summer
A below-ground den is cooler than the surface — practical as well as fun on hot days.

Autumn

Winter
A deep den is remarkably sheltered. Sitting below ground level cuts the wind dramatically — genuinely useful on a cold beach day.
