Carreg Wen Beach is a picturesque sandy bay located in Tremadog Bay, offering stunning views and a range of activities for visitors to enjoy.

Carreg Wen Beach is a beautiful little beach in Tremadog Bay, overlooking the estuaries of the Afon Dwyryd and the Afon Glaslyn. The sandy beach is flanked by rocks and backed by hills and grasslands, providing stunning views across the estuary and towards the snow-capped mountains of Snowdonia National Park in the distance.

The beach is a popular destination for sunbathers during the summer months, although swimming is not recommended due to the presence of strong currents. Visitors are also advised to wear protective footwear when near the water's edge, as weever fish with venomous spines can be found in the waters at certain times of the year. The surrounding area is a good spot for birdwatching and is popular with walkers.

Facilities and parking can be found in nearby Borth-y-Gest, a small sandy bay in a pretty little harbour village between Porthmadog and Black Rock Sands. Borth-y-Gest offers a car park, bus stop, and places to eat, as well as a beautiful church, Saint Cyngar's Church. At high tide, the beach at Borth-y-Gest disappears, but there are other nearby spots to visit.

The estuary habitat of Tremadog Bay is fantastic for birds, with several reserves in the area. This makes the region a haven for birdwatchers and nature enthusiasts.

Carreg Wen Beach is adjacent to the Llyn Peninsula Coastal Path and the Wales Coast Path.
