Ireland can be quite crowded during the peak tourist season, which is from June to August. Popular attractions, especially in cities like Dublin and Galway, can experience high footfall during this time. It’s advisable to book accommodations and attractions in advance to secure your preferred dates and avoid disappointment. However, even during the busiest months, Ireland’s countryside and off-the-beaten-path destinations offer opportunities to escape the crowds. Exploring lesser-known areas or visiting during the shoulder seasons can provide a quieter and more authentic experience.
