Beach Day at Morfa Dyffryn - North Western Region
04 July 2010

BN Beach Day at Morfa Dyffryn, Gwynedd

Make a longer trip of it! We have negotiated a reduced camping fee of £14 for BN members at the nearby Benar Beach campsite. It has a naturist section and makes for a perfect place to stay the night before the beach day.

Call 01341 241001 to book.

So what exactly happens on the bn beach days  ?

Do reps from bn come and promote or organize anything or is it just a normal beach day  ?

I went to the Morfa Dyffryn beach day 2 yrs ago.

The weather was a bit 'average' bright and breezy but there were about 50 or so that attended.
BN were present with the orange tent and free tea and coffee. Naturist info is available to pick up and people mostly chat and sunbathe. It's informal but some beach games were organised including vollyball.
It's basically a good opportunity for people to meet and mix.

I stayed at Benar Beach campsite the Friday and Saturday night with the intention of staying for the BN beach day, but Sunday was blowing a gale and raining. A couple and their daughter packed their tent up and they drove to the beach I can only presume to meet up with others. We decided to make tracks for home. As we were getting closer to home the weather was brightening up so I presume it brightened up at Morfa Dyffryn also. Shame there weren't more people there Friday and Saturday.

Did anyone go? 😮
