I've been going to Tramore, Ireland, most years since I was about 2 years old. And I've probably walked around the Tramore Dunes several times, every year. But I realise I know little about them, so this year we signed up for a tour of the area with a recent ecology graduate. We probably knew more about the area than the tour guide (we were her first ever public tour), but we did learn several new things. For one, the terrain is extremely rare in Europe. There are almost no wetlands like it anywhere in Europe. Some of the last of it has been filled in and used for golf courses in Portugal.
