Graig Wen is a campsite and glamping destination set within 45 acres of wild woods and meadows on the southern edge of Snowdonia (Eryri) National Park, near Arthog between Barmouth and Dolgellau.

Perched on a valley wall overlooking the Mawddach Estuary, the site offers sweeping views down to Cardigan Bay and direct access to the scenic Mawddach Trail, a shared walking and cycling route running along the estuary.

Accommodation ranges from standard camping pitches to glamping options including yurts, shepherd's huts, and wagons, as well as holiday cottages.

The site takes its name from the Welsh for "white rock," a reference to the quartz seams running through the local slate. Cader Idris, sandy beaches, and mountain biking trails are all within easy reach.

Graig Wen has received recognition for sustainability, holding the Green Snowdonia Award for Most Sustainable Campsite.
