One of the cheeky birds even jumped on the rucksack of an unwitting photographer, who had placed the bag on the ground while he took some photos.
In one adorable moment two of the birds were seen nestling their beaks together, while in another image a puffin stands proudly with a beak full of fish.
The birds spend most of the year living out on ocean, but arrived in Skomer in April before departing again in late July.
While staying on the island they sleep in rock crevices or burrows, but for the majority of the year they drift on the open water in enormous colonies.
Professional wildlife photographer Craig Jones has been visiting the island since his school days, and has had a long-held affection for the birds.
The 40-year-old, who lives in Staffordshire, has been visiting Skomer to take pictures of them since 2009.
He said: "I find them quite comical characters, they are so enjoyable to watch.
"I put my bag down on the ground while I was taking some pictures, and next thing I knew they were sat on top of it.
"A lot of animals or birds are quite scared of humans, but puffins aren't like that.
"I have been visting Skomer since I was a boy and have always enjoyed being around the animals."
Puffins have now been added to the International Union for Conservation of Nature's list of animals at risk of extinction.
Although there are millions of them across Europe, changing sea temperatures and extreme weather have an adverse affect on their prey of sand eels, sprats, and other tiny fish.
Roughly 80 per cent of Europe's puffin population can be found in Norway, Iceland, and the Faroe Islands.
However, many still visit Skomer each year and provide an entertaining spectacle for visitors.
