Overtourism like in Barcelona, Venice & Co is fortunately not an issue in Ireland, but anyone who has been to Galway or the Ring of Kerry in the summer would also wish for fewer tourists there. If you are looking for an Ireland off the beaten path, the original Ireland as it once was, then Reisestudio Ikarus, the specialist for trips to the Green Islands, has some valuable tips for you.
One way to avoid the crowds has always been the quiet north of the Republic of Ireland. In Donegal, you can still find original villages and places, wild coastal sections with rugged cliffs, sometimes even abandoned fish factories, but also old trades like knitting factories that still produce today. There are wonderful peninsulas like Inishowen, which have already been famous settings in Irish literature and have not lost any of their magical beauty. You will also find charming small pubs and grocers where you can taste delicious Irish specialties.
Another area for Ireland visitors who want to get to know Ireland as it once was is the Heartlands. This region is essentially the heart of Ireland and spans the area between Sligo and Limerick. There, the Irish spend their leisure time and relax by lakes and rivers or hike along the new long-distance hiking trail Beara Breifne Way - 500 km of breathtaking landscape. Experience traditions and a decelerated way of life, attractions like the "National Famine Museum" in Strokestown Park, which informs about the time of the famine in the 19th century, or the "McKernan Woolen Mills," where you can buy beautiful Irish scarves.
