A sea anemone writhes. Tiny fish dart into the shadows. A crab looks right at you from under a pebble. Nothing quite captures the imagination like a rock pool. Peering through the glassy water into an entire world in miniature is thrilling, and not only for young minds. Each pool is like a soap opera of activity, ever changing, and different tide and tide again.

Whether you’re a dedicated rock pool enthusiast or fancy a quick look as part of a day at the beach, this blog post should be your starting point. Bringing together the best content the RSPB has to offer on rock pools, you’ll know what to look out for, where to find it, how to get the most out of your rock pool experience, and what to do if the weather changes your plans and you have to postpone rock pools for another weekend.

What should I bring?

To ensure you have the best time possible, we’ve created two handy checklists.

Essential rock pool checklist for guaranteed fun:

  • Appropriate footwear (old trainers, strong sandals – something with grip that you don’t mind getting wet for those slippy rocks)
  • Sun cream (it’s hot out there… well, sometimes)
  • Sun hat (keeps the rain off, too)
  • Awareness of the tides
  • A sense for adventure!

Optional rock pool extras for double the fun:

  • Bucket or container (fill it with sea water, keep it shaded, and don’t keep any crabs in it for too long – release everything you find)
  • Bottle scope - here’s how to make one

Make a Bottle Scope

All you need is a plastic bottle (you may even be able to remove one from the beach!), clingfilm, an elastic band and a penknife. Carefully cut both ends off the bottle and cover one end with clingfilm, held in place with the elastic band. Then wrap the whole lot up in black tape to block out the light. Pop the clingfilm end into a rockpool and peer down it to examine the marine life inside. What can you spot?


Where should I go?

There are loads of great rock pooling opportunities on beaches across the country. Find one of our reserves near you, or head to one of these fantastic locations close by for a rock pool ramble or just a day at the beach! Here’s a mix of rough and ready reserves and some of our more equipped ones. Some with rock pools nearby, and a few with a more beachy feel. Always check the reserve site before you visit for up-to-date information and a full list of facilities.


The rock pooling really shines on the west coast of the UK, and England is no exception. But there are places on the east and south coast if you go looking. Northumberland being a notable example of some of the most beautiful coast in the UK.

Walberswick near RSPB Dingle Marshes, Suffolk

We have fantastic reserves just about everywhere, and some of my favourites are in East Anglia. Unfortunately, rock pools aren’t as common here, but Walberswick is a lovely day out and not only close to Dingle Marshes but RSPB Minsmere – a gem of a reserve for all ages. There are great facilities and other things to do in nearby coastal towns and villages, plus Minsmere has some of the best cake I’ve ever eaten!

RSPB Titchwell Marsh, Norfolk

A seemingly endless strip of sand lapped by the North Sea. As you walk through the marshland to the beach, look out for avocet families with fluffy chicks, or even an elusive bittern.

St Bee’s Beach and RSPB St Bee’s Head

The Northwest. Rocky, unspoilt and beautiful. There’s plenty of choice on the Cumbrian coast for stunning beaches with rock pools, but make sure you get to RSPB St Bee’s Head for a seabird sighting before you head to the pools. Facilities run by the council.

Ness Beach and RSPB Labrador Bay, South Devon

The Northwest is great, but for rock pools I’d have to pick the South West (plus I’m a soft southerner). Surfing draws me down here regularly, as does the bird life with star species being Cirl buntings and choughs. Ness beach is a little spot accessed by a smugglers tunnel, and close to RSPB Labrador Bay, which offers spectacular views of Lyme Bay and others. Facilities are close by but not on-site, however.

RSPB Marazion Marsh, Cornwall

Overlooking the mystical St Michael's Mount, this little reedbed fronts a strip of Cornish sand lapped by gentle turquoise waters. Home to more than 250 bird species (incliding Cetti's warbler, sand martins and chiffchaff) and 18 mammal species.

RSPB Arne, Dorset

Has a small, sheltered sandy bay in the calm waters of Poole Harbour, with plenty of bird life. Look out for rare sand lizards among the coastal heather, and Dartford warblers atop gorse bushes.


In my opinion, Scotland’s coast is unmatched. It’s huge for a start, and then there’s everything from the almost Mediterranean feeling beaches of the Western Isles, to the rugged beauty of the north east coast.

Stonehaven town and beach near RSPB Fowlsheurgh, Aberdeenshire

Feeling ready for an adventure? Good. This east coast Scottish reserve is nestled between several wild feeling bays, and once you’re done exploring there, the town of Stonehaven will have all the facilities you’ll need. Plus more rock pools!

RSPB Balranald, Isle of North Uist

Scotland's western coasts are gilded with talcum-white coral sand, lapped by invigorating azure waters dotted with intriguing islands. Balranald is on one of them.


Taeth Crigyll and RSPB South Stack, Angelsey

Seabirds, windswept coast and great facilities at South Stack make it one of the most engaging Welsh reserves, and the nearby bays and beaches mean there’s a ton to do. Wales is a top choice for a family holiday in general if you’re not lucky enough to live there already.

Northern Ireland

Ballycastle Strand and RSPB Rathlin Island

The castle and beach at Ballycastle Strand is pretty epic, and Rathlin Island only makes the whole experience more special. The ferry ride, the views of the Mull of Kintyre, the seals, seabirds and waders – everything. It’s a not-to-be-missed reserve for the UK and a seafaring adventure for the family.

What am I looking at, anyway?

It can be really satisfying to identify wildlife, but also really fun to find something you’ve never seen before. Don’t worry if you don’t know what something is though – discovery is its own reward. Whether it’s a regular rock pool pal or a rare visitor, everyone has a favourite. Here are some creatures sure to get you and your gang excited.

Crabs, hermit or otherwise

Anna, Nature’s Home managing editor has a lot to say about hermit crabs, “These property-ladder climbing little masters of disguise are fun and fascinating to watch - so it’s little wonder that we find hermit crabs so beguiling. I’m putting them at number one for sheer personality. Look for shells moving in a jerkier way than you’d expect from a mollusc.

A lovely description, and hermit crabs are incredible, but where’s the love for the humble shore crab? Infinitely entertaining and accessible, crabs have it all to captivate young ones. Pinchy, scuttly, characterful, and catchable for a close up look. Watch out for the pincers and try to pick up the crab by the leg sides of its shell from above – the widest bit. Don’t keep them too long though; they have important crab business to attend to.


“Our most common starfish has five arms covered with white pimples, and can reach 30 cm across. Its suckery little feet can prise a mollusc shell apart enough to slip a bit of its own stomach in and secrete enzymes to liquefy the shellfish inside... but if needs be, they can survive several months without food (though they'll shrink).” Anna says.

I haven’t seen a starfish for a while in the UK. Other species to look out for are spiny starfish, cushion star, bloody Henry starfish, and brittle star. See if you can find all five of this summer!

Regularfish (blenny and goby)

Several species of goby can appear in rock pools, and they’ll stand out from the crowd being little tiny fish. The real star here though is the semi-amphibious blenny, that will slip and crawl over rocks between pools, or hide up in some wet seaweed until the tide returns. Entertaining survival techniques.

Shells glued to rocks, aka limpets

According to Anna, “The king of the clingers, the rock-pool VIP… Limpets boast the strongest muscle tissue of any animal, holding on with an incredible force of 75 lbs per square inch! They use a sharp, rasp-like tongue, hidden somewhere under there, to graze algae off the rocks, along with seaweed seedlings. Their shell shape is affected by wave flow, how long they spend out of water and how stressed they are - a relaxed and well-fed limpet has shallower contours. See? They’re fascinating!”

Anenome (beadlet anenome)

“Out of water, they’re a strange mound of reddish jelly up to 5cm across. But those below the waterline send forth an impressive crown of 192 waving, fluttering, sticky-tipped tentacles, arranged in six circles. It can sting its tiny prey, but is harmless to humans. It can tolerate very warm water and can even survive being temporarily dried out - and its mouth is also its bottom, and ejects ready-made babies out into the water, where they land on the rocks and set up home. I adore everything about this bizarre animal.”

Well that does sound bizarre. If that doesn’t blow your kid’s mind I’m not sure what will.

Look at the weather! What now?

Surprise surprise, it’s raining – again. One option is to listen to these wise words, “There’s no such thing as inappropriate weather, only inappropriate clothing." – Alfred Wainwright. Or not if it’s really pouring. Don’t worry either way, we’ve got just the thing to bring a rock pool inside. Let’s craft some rock pool wildlife and bake a rock pool cake!

Paper craft first, baking later

Make your own paper octopus, urchin and crab, plus loads of other fun things to do, inside and out, on our Pinterest page

All that handy work has made me hungry!

Rock pool cake without the sand

It’s all about the decoration for this cake, and you can apply this design to almost any cake – or giant biscuit for that matter. It’s easy, and fun to make as a family.

For the cake

  • 2x Victoria sponge cake mix (or make your own favourite cake for decorating)
  • We added 50g raisins and 100g glace cherries to our to jazz it up
  • Jam for between the layers

For the buttercream

  • 125g unsalted butter, softened
  • 250g icing sugar
  • 1 tbsp vanilla bean paste

For the decoration

  • 75g custard creams (about 6, but depends how sandy you want to go)
  • 2 tbsp brown sugar
  • 150g ready-to-roll white sugarpaste
  • Blue and black food colouring
  • Strawberry laces
  • Red chocolate sweets
  • Fizzy apple strips


  1. Cream the butter, icing sugar and vanilla bean paste and spread over the whole cake
  2. Knead 100g of sugarpaste with one or two drops of black food colouring until it marbles. Roll different size pieces into balls to make rocks and put to one side
  3. Knead the rest of the sugar paste with one or two drops of blue food colouring until marbled. Roll out flat and round and put to the side
  4. Put the biscuits and brown sugar in a sandwich bag, seal it, and bash with a rolling pin to make sand. Spread the sand on the top of the cake
  5. Add the blue pool to the top of the cake, and surround with rocks
  6. Now for the finishing touches! Create crabs from red sweets and laces, and seaweed from fizzy apple strips

Try the RSPB’s Wild Challenge this summer – kick off your go-for-gold with rock pooling. All you have to do is register online and tell us what you saw when you went rock pooling. It’s easy, and there are tons of activities to do all year!

Rock pooling as a child has stayed with me for life. It is utterly engrossing for a young person, and one of the most accessible ways to get up close to wildlife.

Connect with nature this summer and get your feet wet in a rock pool!

  • I remember doing this few years ago, it was really fun. My friends with me are always freaking out with almost anything  that they see lol! Also, we can't stand to just walk bare footed, there are a lot of weird stuff underneath!
