The motorway is for sure the fastest and quickest way to get to the Wicklow area, but it is not the only way. If you have time you can drive Sally’s gap. Apparently it is pretty inaccessible in the winter.
It it a very narrow and windy road that runs about 30km from the South of Dublin.
As you can see you get striking scenery as you go along. Remember to drive on the left and you will have to pull all the way over to let people pass going the other way. There are several viewpoints where you can pull over and take pictures.
The road was built by the military so they could find criminals that were hiding in the hills. It is now aptly named Military Road.
