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.

How to Dig It — Steep Shingle Beach Edition
- 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.
- Seal the paper inside a small waterproof container, such as a screw-top jar or a resealable freezer bag wrapped in another bag.
- 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.
- Dig a hole around 20–30cm deep, place the container inside, and cover it completely.
- 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.
- 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
