I researched a LOT of tours in Ireland, both private and public. Little Gem Tours was the easiest to work with; they responded the quickest, had the most user-friendly website, were the most reasonably priced, and were extremely flexible with our itinerary.
I traveled with 3 other adults and one 10 month old baby to the Wicklow Mountains, Glendalough, and Powerscourt Estate. Robbie was our driver and he was amazing. His knowledge of Irish history and fun facts made our trip so much better. We learned a lot and he knew the right places to take us. You will have to see the pictures to see how stunningly beautiful it was. Traveling with a baby isn't easy, but he made the trip comfortable and changed the itinerary throughout the day based on her needs.
I only wish we could have stayed in Ireland longer and taken more trips with Robbie. We loved the whole day. I'm SO glad I stumbled upon Little Gem Tours online.
