Among the most well known Irish visitor attractions are the Cliffs of Moher in County Clare which lie roughly equidistant from Galway and Limerick at about an hour and a half by car. There is plenty of good parking available with some shops, a cafe, and an interpretative centre onsite.
If, like me, you arrive hungry hold off on eating at the cafe inside the door of the interpretative centre and instead head up the stairs where there is more seating and better views.
There is an admission charge to the Cliffs of Moher and, at the time of writing, you can get a discount if you book tickets online at the Cliffs of Moher website in advace.
Be prepared for a short walk from the car park to the entrance to the Cliffs and then more walking depending on how much time and energy you have to spare.
There are plenty of good vantage points within a relatively short distance of the interpretative centre with excellent views including views of the Aran Islands.
On a sunny day, this is a great place to visit and if you allow enough time you would also be able to take in the famous Burren national park which is just a short drive from the Cliffs of Moher.
