Seals in Pembrokeshire
See Atlantic grey seals in Pembrokeshire by sea kayak — or your money back
Pembrokeshire is home to one of the largest breeding populations of Atlantic grey seals in the world.
Every autumn, hundreds of seal pups are born along this coastline. For a few short weeks, white-coated pups rest above the tide line while their mothers nurse them on some of the richest milk found in the animal kingdom.
If you join us during September or October, we guarantee you will see seals — or your money back.
Seals in Pembrokeshire: Atlantic Grey Seal Colony
The species found here is the Atlantic grey seal (Halichoerus grypus).
At birth, pups weigh around 14–16kg and are covered in thick white fur. Over the next three to four weeks, they treble in size thanks to milk that is nearly 60% fat.
During that time, the mother does not feed herself. She remains ashore, nursing her pup while losing up to half her own body weight. Once the pup has moulted its white coat and developed waterproof fur, the mother returns to sea.
Shortly afterwards, breeding takes place. Interestingly, females can delay implantation of the fertilised egg for up to three months — a strategy known as delayed implantation — ensuring that next year’s pup is born at the optimal time.
It is an extraordinary cycle.
Why Sea Kayaking Is the Best Way to See Seals
Sea kayaks allow quiet, low-impact access to remote coves and beaches that are unreachable on foot.
Unlike powered craft, kayaks move silently. As a result, seals are rarely disturbed and often remain relaxed in their natural behaviour. Occasionally, curious juveniles will even approach the kayaks.
When young seals first take to the water, they are inquisitive. They circle, peer up at paddlers and sometimes gently investigate the hull of the kayak. It is playful, not aggressive.
They remind me of Pepper, my chocolate Labrador when she was a puppy — curious, bold and full of personality.
Responsible Wildlife Viewing
Seal welfare always comes first.
We do not land on pupping beaches during the breeding season. We maintain appropriate distances and adjust routes depending on tide and behaviour. Access to certain locations, such as the Witches Cauldron, is restricted during autumn because seals use the beaches there.
Our trips are led by a Wildlife Safe Accredited Guide, ensuring best practice at all times.
