We agree with the twotwitchers review, and we went for the same reason. The RSPB reserve is wonderful, so many different habitats. Mr and Mrs Griffiths are really helpful and also very interesting to talk to. The maintenance of the site and the facilities are exemplary and the site large and the power points well spaced. We have booked another five days in August when we plan to visit Ynys Hir again but also do some walking in the hills immediately accessible from the site. The only drawback for motorhomers like us who don't like to drive about in it much is that there is no shop nearby, but we were fairly well stocked so it was not a problem for us.
