This is a guided tour of the island which a group of MountainViewers had. The trip started from Rogerstown Pier near Rush in Co Dublin with a trip in an inflatable. This brought us to the small harbour on Lambay.
From there we briefly popped in to a room in the "White House" a largish accomodation block near the harbour, made available by the tour company. The walk took in the highest point on the island which appears to be at least partially a water reservoir and then on to the east most extremity.
The island is volcanic in origin and is well known for porphyry a type of volcanic rock in which are embedded crystals. This rock is very hard and according to one MountainViewer, Lambay has two megalithic quarries from which this rock was mined and exported.
There is a lot of wildlife including rabbits (somewhat depleted at present), fallow deer, various species of birds such as guillemots and, famously, wallabies. We saw all but the last.
The day we were there was fairly misty however we could see the odd sight of the Great Sugar Loaf in Co Wicklow poking up above the Howth peninsula.
