The tour starts in Dublin, on the east coast, and ends in Clare, on the west coast. We therefore suggest that folks fly into Dublin and out of Shannon. Having looked on the various websites we have not seen any significant price differences in this flight route. We encourage people to fly in at least 1 day prior to the start of the tour to acclimate to the time difference and also for unforeseen travel or luggage delays. You may also wish to use this opportunity to explore Dublin yourselves prior to embarking on the tour.
