Visiting at the beginning of March is a wonderful time of year, as the weather gets warmer, and it is not quite peak season. It is possible to park your car at the Visitor Centre of the
Cliffs of Moher, and explore the area on your own, without a tour guide. If you buy your
tickets up to at least one day in advance, you receive a 50% discount off the original price as well.
Galway is filled with history, and there are many historical walking tours to choose from. Take a look at the options
