If you're hoping to catch sight of a seal at the Giant's Causeway, the autumn season may be your chance.
National Trust rangers say seals are wary of humans, which is why they are rarely seen coming out of the water onto the rocks and islands closest to the Giant's Causeway.
But from September to December, grey seals breed on the Causeway coast and can often be seen playing off shore.
The best time to spot a seal is when the tide is out. Grey seals prefer the wind and wave swept rocky shores. Their pups are born white-furred and remain on land for three to four weeks until weaned.
Every so often a young pup can get lost on the shore at the Causeway, and will need to be guided back to the sea by rangers.
There are two types of seals common to Northern Ireland. The grey seal is more common and has a long nose and straight nostrils. Common seals have 'V'-shaped nostrils and can be found visiting old fishing harbours around the coast.
