Ashydoo Kirk and a Victorian Horn House.

The main sea bird breeding colonies on Ailsa Craig are found on the western craigs.

High above the distant Kintyre peninsula, the western sky is full of gannets, guillemots, razorbills, black guillemots, fulmars and kittiewakes.

At this spot known as the Bed of Grass, puffins have re-established themselves after the island's rats were eradicated.

They whirr in and out from the sea on rapidly beating wings.

This guano covered rock is favoured by cormorants and is known as Ashydoo Kirk.

Once past Ashydoo Kirk the vertiginous cliffs rear up even more steeply into the huge rock wall which is known as...

...Bare Stack.

Now wonder we had cricks in our neck after gazing up at such wonders.


At last we reached the north end of Ailsa Craig where the hand of Man again becomes visible...

...as you pass the site of the great Victorian horn horn which has stood here...

...since 1886. A 12 inch diameter cast iron pipe carried compresses air at 75psi from the compressor in the building near the lighthouse which Tony and I had explored just a few hours before. The compressor was powered by a 38hp Crossley ‘Otto’ silent gas engine which was powered by coal gas from the gas works.This arrangement lasted until 1911 when the gas engine was replaced by an oil burning engine. The fog horn was finally abandoned in 1966. At the gas works all the engine and compressor machinery was duplicated to drive the south fog horn.

After the foghorn we passed the rubble which lies below the site of the blue hone granite quarry which produced the finest granite for the curling stone industry.

As it was mid June, the local gulls were nesting on the waste rubble from the quarry.

 We had now arrived back at the spit under the lighthouse. Our crossing to and circumnavigation of Ailsa Craig were completed but the day was not yet over....

A blizzard of gannets does not deposit snow on the rock ledges of Ailsa Craig!

After Phil had partaken of a solo luncheon while Tony and I explored the industrial archaeology of Ailsa Craig, we set off on a clockwise circumnavigation of the rock in late afternoon.

Top tip: on a visit to Ailsa leave the circumnavigation till last. This means that the sun will be well round on the W and NW breeding cliffs and by going clockwise, the sun will be behind you for best viewing.

As we left lighthouse spit, several large grey seals followed us and indeed passed under us.

 Initially first time visitors wonder what all the fuss is about.

 Yes the cliffs on the SE side are suitably steep but there are not many birds about.

 However, as soon as you pass the foghorn at the south east end of the island...

 ...the cliffs at Trammins rear up in a most impressive manner. pinkish vertical columns of rock are topped by white capped ledges. From a distance it looks like snow but...

 ...once you get a little closer your olfactory system will become so overloaded that you will realize that this is not snow but the finest gannet guano!

High above us squadrons of gannets are flying out from their ledges. There is order in the seeming chaos. Birds on lower ledges fly first and birds on the top ledges fly last.

 The air above us was filled with a blizzard of...

 literally thousands of gannets.

It is therefore advisable to wear a broad brimmed hat on a circumnavigation of Ailsa Craig.  At sea level there is also interest. This isolated rock is known as Little Ailsa.

 Just beyond Stranny Point lies the Water Cave and the main breeding cliffs on the west of the island. Our taste of guano on the south coast had been merely an amuse bouche.
