Rock Pool Habitat
On a Sheltered Cove
Dig your own rock pool to give crabs, shrimp, and whatever else the tide brings in a temporary home — adapted for sheltered cove conditions.
About This Hole
A shallow, wide pool dug with a rocky or shell-lined base, designed specifically to hold water and shelter for small sea creatures caught while rock pooling — a gentler, more purposeful cousin of the standard sand pool, built for observing wildlife rather than just for paddling.
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.

How to Dig It — Sheltered Cove Edition
- Choose a spot close to where you're collecting from, on flat sand just above the waterline.
- Dig a shallow, wide pool, no more than 20cm deep, with gently sloping sides so small creatures can't easily climb out.
- Line the base with a few flat stones, shells, or a patch of seaweed for shelter and somewhere to hide.
- Fill with seawater carried by bucket, or positioned close enough that the tide tops it up naturally.
- Add creatures gently — small crabs, shrimp, or anything caught while rockpooling — and always return them to the sea before you leave.
Variations: Dig several connected pools of different depths to sort creatures by size, or add a small channel connecting it to the sea so it refreshes naturally as the tide comes in.
Seasonal Tips for Sheltered Cove
Spring
A good season for rockpooling generally, with plenty of small creatures active in shallow water.
On this beach in spring: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.
Summer
Keep the pool topped up regularly — warm summer sun heats shallow water quickly, which isn't comfortable for anything living in it.
On this beach in summer: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.
Autumn
Cooler water and calmer conditions often make creatures easier to spot and catch.
On this beach in autumn: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.
Winter
Fewer people digging means fewer disturbed rockpools nearby — good conditions if you're wrapped up warm.
On this beach in winter: Limited space. Sand can be coarser and harder to work with finer tools. Cliffs can drop debris.
