2005. I took a trip down to Snowdon in North Wales. At an altitude of 1,085 m (3,560 ft) above sea level, the peak is the highest peak in Wales. I think I remember reading somewhere that Snowdon has the wettest altitude of anywhere in the UK but during my visit, the skies were blue and the sun shone. I could be wrong here but I think Snowdon is the peak to the right of this picture.
