The iron spike on the summit of Ailsa Craig.

Near the summit of Ailsa Craig  this old iron stake was used in the 19th century by men who lowered themselves on ropes to the gannet colonies below. They harvested the young gannets in the same way that the inhabitants of St Kilda did at the same time.

 With knees like mine I stayed put but Tony bravely descended (without a rope) to see if he could get photos of the colonies.

The grassy slopes got steeper and steeper and Tony returned to the easier ground of the summit with some relief.

 I took this photo (from the spot Tony reached) in May 2008 before my knee accident. It shows the gannet colony at the top of these...

...cliffs on the western side of the island. It is not the sort of place you would want to slip!

We had intended to stay on the summit until sunset but I realised my knees would not manage a descent in the dark. Phil and Tony kindly agreed to accompany me down and we slowly descended together on  the shady path on the east side of the island. We were not alone,...

...this yacht was slowly trying to break free of the island's wind shadow. It was long gone by the time I got back to sea level!

From the summit of Ailsa Craig you can see for miles and miles and miles...

When our camp site on the lighthouse spit was cast into the shade by the bulk of Ailsa Craig, we decided to climb to the top and watch the sunset. The steep path up to the castle gains height very quickly and I struggled to keep up with Phil and Tony.

As we ascended we caught sight of the huge shadow cast by Ailsa Craig on the sea far below.

I feel behind the others again as we climbed the flower filled Garry Loo, a long depression in which the Garry Loch can be found in wet weather.

At last we broke into the sunshine at the summit cairn and trig point which is 340m above sea level.

We peered over the edge down to the lighthouse fro where we had started our climb. You can just see our tents by the corner of the lighthouse wall.

The seacat HSC Express roared past on her way from Troon to Larne.

It was good to take a rest on a rock. We gazed over towards Campbeltown where Tony and I had set off from 48 hours before.

This gannet swooped in from the direction of Mull of Kintyre and Sanda Island. Its belly was full of fish to feed its chick on the ledges below.

 To the north the whole of Arran was laid out before us.

Looking north past Holy Island we saw the southern edge of the highlands from Ben Ime and the Arrocher Alps to Ben Lomond.

 To the east the town of Girvan was backed by the Galloway Hills which are crowned by the Merrick.

To the north east we could see Turnberry Hotel and lighthouse, Culzean Castle and Mochrum Hill and the Carrick Hills rose beyond.

Sun seekers with ants in their pants keep the pot on the boil at Ailsa Craig.

We set up camp on Ailsa Craig  on a grassy ledge next to the lighthouse wall.

 We were by now pretty hungry and soon...

had the pot on the boil.

Unfortunately we discovered a number of ant's nests in the grass. Phil had been sitting cooking his dinner when all of sudden he leapt to his feet. These were biting ants and he had ants in his pants!

At 17:35 the 16:15 Larne to Troon (arr. 18:30) Ferry HSC Express crossed the line between Ailsa Craig lighthouse and Pladda lighthouse. It was 1 hour and 20 minutes out of Larne and was running about 5 minutes late.

This was the view of the Express and Ailsa Craig from the south end of Arran just 24 hours before.

At 18:36 on 17/6/2014, the spit at Ailsa Craig fell into the shade of the great bulk of the island. So what would three sun seeking kayakers do?

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.
