County Meath Day Trips from Dublin

We will be in Dublin at the end of May. We'd like to find a day trip to County Meath to see some of the historic sites. Can anyone recommend a reputable company with knowledgeable guides? 

Hi Ken, 

It's great to hear you are visiting us at the end of May. In terms of day trips from Dublin, the Celtic Boyne Valley Day Trip is very popular and covers Meath. With an expert guide, journey back in time to Boyne Valley, home of the ancient Loughcrew Celtic Tombs, the Hill Of Uishneacht, and the Hill of Tara—a hotbed of archaeological treasures. Along the way, view primeval sites across Meath and Louth counties. 

Let me know if you have any other questions, and I would be happy to awnser.
