Local Reef "The Kilstiffin Reef" - Legend

The reef of Kilstiffin has a legend of a sunken church and city.The city Kilstiffin has also been called Kilstapheen, or Kilstuitheen has a legend of a sunken church and city, of which the golden domes appear once in seven years. The city sank when its chieftain lost in battle a golden key, a key which used to open the door of a fine castle there. The city will not be restored until the key is recovered from its unknown location – some say it lies under the ogam-inscribed gravestone on Slieve Callan, east of Milltown Malbay, while according to others it was thrown into the little lake on the top of that mountain. The city, with its golden-roofed palaces, churches, and towers, may at times be seen shining far below the surface. Once in every seven years it rises above the waves. But beware!! It is said that those who catch a glimpse of this city will die before it appears again...

Kilstiffin Reef - Canyon

Description: A canyon cut into the reef, which runs towards Lahinch for about 300m, the sheer sides reaching to the bottom at 25m. At no point is it any wider than about 10m, with many “shelves” lined with the best of what the Atlantic can offer. The cleft ends in a large cave at the inner end.

Kilstiffin Reef - Cathedral

Number of buttresses can be found close together at 20m which look very like those found supporting the side walls of cathedrals.

Lime Rock

Description: This is a long, low, rock running east-west. There is a broken drop-off for most of the length of the rock. Of interest are several very large steep-sided “pots”, some are up to 10m deep, close in to the rock. These were caused by the action of boulders being whirled around on the softer rock by wave action. They are usually clean of kelp inside, but well worth a look, there is often the large boulder at the bottom which caused the hole to be made.

  • Depth range: 15-30 m
  • What to see: 

North Seal Rock

If moving east, it is possible to find the opening between the Seal and Lime Rocks, passing under a large overhang into shallower sheltered water of the Rock. A very large tuna was sighted there. 

  • Boat journey: 25 min.
  • Depth range: 15-35 m
  • What to see: Grey Seal, Lobsters

South Seal Rock
