Pen-y-Llyn has two sites – a 5 pitch CL and a more commercial site with 15 pitches. The two are quite separate apart from sharing the access road into the sites. All pitches are well maintained & wide/deep stone hardstandings with power & water points at each location. The grassed areas were well maintained and there was a welcome secure dog walking area to allow the hounds to run free. As others have said, the beach is about a 20 minute walk away but then you have a wide sandy shoreline all the way to Rhosneigr where there are shops & hostelries. It is also a “dog friendly” beach. One thing to be aware of [& we should have read Catherine’s welcome pack!] is that there is a creek running across the beach near Rhosneigr which needs to be forded! So be prepared to get wet feet! The closeness to RAF Valley does mean that there is quite a bit of aircraft noise during the weekdays with the planes doing circuits. This could be a bit intrusive if you were on site all during the day but we were away for most of our time there and they don’t fly at weekends. Overall, a lovely CL with caring & approachable owners who ensure that you have a pleasant stay.
