Rockpools are some of the most fascinating places to explore on the UK coast. When the tide goes out, small pools of seawater are left behind, each one holding a tiny world of colourful creatures. You do not need specialist knowledge to enjoy rockpooling. Once you know where to look and what features to notice, these small habitats become full of life.
This guide introduces the species you are most likely to find in summer, how to explore rockpools gently, and where to visit along the UK shoreline.
If you enjoy exploring coastal wildlife, our Beginner’s Guide to Wildlife Watching at the Beach introduces other species you can find along sandy and rocky shores.
Rockpools form when the tide retreats, leaving seawater trapped in hollows and cracks. These pools become temporary homes for small fish, crabs, anemones, shellfish, and many other creatures. Summer is the best time to explore them. Warm weather, calm seas, and low tides reveal more pools and make wildlife easier to spot.
Today:
Their presence shows how rich and varied our coastal ecosystems can be.
Many creatures hide under stones or cling to the sides of pools. Slow movements help you notice details.
Small fish often dart just below the surface. Crabs may move between shadows.
Lift stones gently and always place them back exactly as you found them. This protects the creatures that shelter underneath.
Rockpools hold bright reds, greens, and blues from seaweeds and anemones.
Low tide gives you the best chance to explore safely.
Once you have explored a few pools, the patterns become familiar.
A small crab often found under stones. Green or brown in colour.
A bright red anemone that closes into a smooth blob when disturbed.
A cone shaped shell that clings tightly to rocks.
A small fish that hides in crevices. Often curious and may watch you from the shadows.
Some pools hold small starfish resting on rocks or sand.
These species are widespread and ideal for beginners.
Cornwall and Devon have excellent rockpooling beaches.
The Gower and Pembrokeshire coasts offer rich pools with many species.
Rocky shores along the west coast and islands hold colourful marine life.
