“The Dublin Bay Coastal Trek” is a 15k stroll along the coast from Dublin To Dun Laoghaire. It operates on Thursday and Sunday till the end of September. Other days or longer stretches to Killiney by negotiation. I also have registered The Official “Dublin Camino” which beings in July.
This tour is designed for those who like to walk about on holiday rather than drive or sit on a bus. It is approx 15 k in about 4 hours.
