Morfa Dyffryn Beach (Bennar Beach, Llanenddwyn)

Dyffryn Beach is situated on the coastline of the scenic Cardigan Bay and is well known in the area for its fine sand dunes. The dune system around the beach is actually part of a wider National Nature Reserve and you will need to apply for a permit from the Countryside Council for Wales if you want to explore them. When it comes to the beach itself, it has a good claim to being one of the most beautiful beaches in Wales.

The central part of Morfa Dyffryn, as it is known in Welsh, stretches for miles and sand dunes rise behind the beach coupled with vast expanses of scrubland. The sands of Morfa Dyffryn are clean and soft and extend into the sea at a gentle slope so that you can easily swim here, even if you have children as there are no sudden ledges to avoid.

Behind the beach you will also be able to take in views over majestic Snowdonia as well as the mighty Rhinog Mountains. As you look out across the sea you will find Tremadog Bay and the wider Llyn Peninsula. And if you’re lucky you might catch a glimpse of the local dolphins.

The beach here is perhaps best known as an officially recognised naturist beach. The nudist section of the beach is separate from the main area but still stretches for around a mile. Dyffryn Beach has been used as a naturist beach since the 1920s although in recent years clear signage has been added to make clear where this area begins and ends. It is usually used by a mixture of visitors including families, but it is worth noting the naturist area is around 30 minutes walk from the nearest car park.

To get to the beach there is a new boardwalk that stretches from the Snowdonia National Car Park through the dunes which offers disabled access. You should note however that it is a rather long walk although it is mostly flat.

1st visit in June 2021 - spent the day on the clothing optional section and loved it!
Glorious Friday - sun with a light breeze - perfect sunbathing conditions.
A variety of people on the beach but probably 80% male but very relaxed and friendly.
will be back:-)

I was on beach here last year as I got a little close to the land.
After a few rolls and pushes I managed to get back out to sea

Had 1st skinny dip there last August at 60. Most user friendly beach, only thing to beware are jellyfish. Very little plastic debris washed up when I was there. Nearest such beach to me (living in Welsh border England).
