Welcome to Cornish Rock Pools

Thinking of going rock pooling in Cornwall? You’ve come to the right place.

Read on to find out where and how to rock pool, what you might find, my latest tips and discoveries and groups to join if you want to learn more.

There’s something about rock pooling. It’s a window on the underwater world. It’s the freedom of wandering between the blue sky and sparkling sea, never knowing what you will find. It’s a joy every child should experience, and that every adult should rediscover.

Early summer is a great time to find fish eggs under boulders (take care to return rocks quickly to how you found them). When the eggs are nearly ready to hatch you can see each fish, its eyes looking out and a little tail wrapped around itself like a scarf. Look closely for sea slugs from the Calma family that feed on fish eggs. I was lucky enough to record two Calma gobioophaga slugs over the last couple of weeks.


I’m delighted that Cornish Rock Pools has twice been named ‘Blogger of the Week’ in 2016 and 2017 by the BBC Wildlife Magazine. My first award was for my report on finding and photographing these gorgeous Scarlet and gold cup corals. Read more here.
