We hailed a cab instead of taking the shuttle bus and ended up finding a great driver who talked us into going to Powerscourt Gardens. We negotiated a price of $50./hr for the 3 of us and it was one of the highlights of our trip. We drove through downtown Dublin on the way home and this took 3 hours altogether. If anyone is interested and would like to know his contact is AntonyTaxiCab@hotmail.com or phone 00353 0857142946. We would highly recommend Antony as being knowledgeable and accomodating. Powerscourt Gardens is an absolutely beautiful place to spend a part of a day and the drive to and from there was very pleasant.
