Time Capsule Hole

On a Sheltered Cove

Bury a message, a memory, or a wish — and dig it up another day — adapted for sheltered cove conditions.

About This Hole

The gentlest project on this list, and the one with the least to do with engineering: children write or draw a message — a wish, a memory of the day, a note to their future self — seal it in a waterproof container, and bury it somewhere memorable on the beach. Unlike every other hole here, the point isn't the digging itself but what happens afterward: marking the spot, remembering it, and coming back to dig it up on a future visit.

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.

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. Have each child write or draw something on a small piece of paper — a wish, a favourite memory from the day, or a message to themselves for next time.
  2. Seal the paper inside a small waterproof container, such as a screw-top jar or a resealable freezer bag wrapped in another bag.
  3. Choose a spot well above the tide line, ideally near a landmark that won't change, such as a groyne, breakwater, or fixed dune marker.
  4. Dig a hole around 20–30cm deep, place the container inside, and cover it completely.
  5. Mark the exact spot with a photo, a note on your phone, or a description in relation to the landmark, since sand shifts and the exact position can be surprisingly hard to recall.
  6. Agree on a return date — the next holiday, next summer, or even just 'the next time we're here' — and dig it up together to reread the message.

Variations: For a family group, bury one shared container with a message from everyone rather than individual ones. For a longer-term version, note the GPS coordinates on your phone if you're not confident the landmark will still be there next time.
