Newgrange
Not worth it!
A review of this place: Better prepare for a long wait, or not to get in at all — 2 years ago
We visited Newgrange in April, 2006. We arrived relatively early in the day, but even though the tourist season had barely begun, we were told that all the tours for the day were booked up, and we would not be able to get close to Newgrange itself unless we were with a tour. So we basically got a nice view of it from the road, from a quarter mile distance.
