Time Capsule Hole

On a Steep Shingle Beach

Bury a message, a memory, or a wish — and dig it up another day — adapted for steep shingle beach 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

Pebble and shingle beaches slope sharply into the sea. While you can't dig a traditional sand hole, the loose stones allow for brilliant channel, dam, and moat building above the tideline where any small amount of sand collects. Think construction more than excavation.

Compatibility

Possible but challenging — work with the beach's natural conditions and scale your ambitions accordingly.

Safety — Beach: Steep gradient makes it easy to slip into the sea. Keep younger children well back from the water's edge.
Safety — Digging: Never leave a deep hole unattended. Fill it in before leaving the beach. Keep walls sloped, not vertical.

How to Dig It — Steep Shingle Beach Edition

Conditions on this beach: Pebbles, cobbles, and coarse gravel — with pockets of coarse sand in hollows. Steep gradient means tides arrive fast. Always stay aware of incoming waves.
  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.

Seasonal Tips for Steep Shingle Beach

Spring

A nice activity to start a longer tradition, ahead of a summer return visit.

Summer

Popular as an end-of-holiday activity, timed to be dug up on a return trip the following year.

On this beach in summer: Stones shift and collapse more than sand. Hands and knees take a beating — gloves recommended. True hole digging is limited to sandy pockets.

Autumn

Works well as a lower-energy activity on a cooler, calmer beach day.

On this beach in autumn: Stones shift and collapse more than sand. Hands and knees take a beating — gloves recommended. True hole digging is limited to sandy pockets.

Winter

A good indoor-adjacent option — write the message at home and just make the short trip to bury it.
