Dowth, Knowth, Newgrange in the valley of the Boyne. Tara. My friend & I travelled to Ireland for 2 weeks in July of 2002. We started at Newgrange and then went on to Carrowmore, Carrowkeel, the Burren. I highly recommend visiting them in the sun or rain. Rain makes them even more special. High clearance vehicle for Carrowkeel. Visit www.megalithomania.com for pics and info on megalithic sites throughout Ireland.
