If you are lucky enough to go to the Aran Islands in County Galway, West Ireland I would most definitely recommend that you consider hiring a bike. The main Island is Inish Mór which houses the impressive semi-circular stone fort of Dún Aonghasa perched atop the towering cliffs.
The island is approximately 14km long and 3.8km wide and its small narrow lanes and tracks make the bicycle the ideal means of transport. While these images were taken on a flat grey day and on an old camera, hopefully you will get a sense of why I would recommend a bicycle to get around. There are many bicycle hire places on the Island and a free drop off and pick up service can be provided by most.
On this last Photo Mr Sage shows Mrs Sage the way, right until the road began to climb anyway.
