My wife and I had never stayed on Anglesey before, we decided to spend a month at Pen Y Llyn having been made to feel so welcome on our fact finding mission. Geoff and Catherine were so helpful throughout our stay nothing was too much trouble. As it happened we celebrated our 40th wedding anniversary during our stay. Catherine was so helpful to me when making special arrangements for the day. Both Geoff and Catherine work very hard to keep the site in tip top condition and anyone not enjoying their stay should really "get a life". Being close to RAF Valley the jets were a little bit noisey, however after a while it became the norm. I recommend this site very highly and look forward to spending another month with Geoff & Catherine in 2018.
