A peaceful, boutique B&B in glorious Snowdonia National Park.

The folks behind the glamping and camping and cottages at Graig Wen also run a lovely boutique B&B, housed in what was once a Victorian slate-cutting mill. There are five (dog-friendly) rooms, decorated in a bright, contemporary style and equipped with flatscreen TVs, free wifi, posh toiletries, lovely Welsh wool blankets and bath robes. They welcome you with chocolates and a drink, and you can soak up the fabulous views over the Mawddach estuary during your stay (rooms Bran or Miri Mawr have the best views). Breakfasts are yummy, too, with everything sourced from local farms or friends and family – and a breakfast hamper delivered to you if you're feeling lazy. Meanwhile, everyone is welcome to enjoy the spacious communal Caban area with stunning views, honesty bar, books, maps and games.

There's tons to do in the local area, from hiring a bike and cycling to the local pub to hitting the nearby beaches, just five minutes away. Tackle Cader Idris, the spectacular mountain right at the back of Graig Wen, or explore a stack of  challenging mountain-bike trails at nearby Coed-y-Brenin, around 5 miles north of Dolgellau. From your room, you can walk directly through the surrounding 45 acres of wild woodland and meadows to the edge of the Mawddach Estuary and Mawddach Trail. Plus, Harlech Castle, Portmeirion and the Ffestinniog steam railway are within easy reach. It's also a fabulous place for star-gazing, with some seriously dark skies in this part of the National Park.

Here at Graig Wen we also have a small camp site with a Shepherd's Hut, yurts and four family friendly self-catering lets .

Suitable For

Miri Mawr is a colourful and snug room which overlooks the Mawddach Estuary.  An ancient oak tree outside the window is home to owls and woodpeckers.


You'll find beaches 5 minutes away and Coed y Brenin mountain biking centre within 15 minutes. With Cadair Idris mountain range on the doorstep and horse-riding on the beach nearby, The Slate Shed bed and breakfast in Snowdonia National Park is a tranquil and beautiful base for activities. The zip wires and Bounce Below at Blaenau Ffestiniog are just 30 minutes away.

Food & Drink

You have a wide choice for eating out within 5 - 10 minutes drive every day of the week. There are excellent local restaurants, pubs, bistros and cafes including four restaurants featured in the Michelin Good Food Guide. We are very happy to help you with advice and advance booking, which is strongly recommended for both tables and taxis at weekends and busy times. Whether you fancy Welsh lamb, fish and chips by the beach, or good pub grub with a screen to watch the rugby, we'll help you find it here!

You can walk, or even better, bike to a couple of local pubs. It's an hour and 15 minutes walk along the beautiful Mawddach Estuary Trail, or 25 minutes by bike on cycle path all the way to the recently refurbished George III at Penmaenpool. Or you can take the Mawddach Trail over one of the most iconic and scenic bridges in the country to the pubs and cafes of Barmouth. You can borrow a bike from us.

Some of our favourite local restuarants include: Bwyty Mawddach , The Salt Marsh KitchenIndiana Cuisine, Tafarn y Gader Tapas Bar, Dylanwad and Bistro Bermo. And it's always hard to resist having second helpings of Meg's amazing cakes at TH Roberts cafe in Dolgellau!


Closed for B&B Nov–Jan.


B&B rooms £90–£130 a night. They take children over the age of 10 but all the rooms are either doubles or twins, so the self-catering cottages are best for families.

The Owner Says

Our stylish Bed and Breakfast accommodation in Snowdonia National Park has an incredible location overlooking the Mawddach Estuary - one of the most beautiful views in Wales!

The Slate Shed B & B at Graig Wen provides pet friendly, bike friendly and accessible accommodation in an exceptional location in Snowdonia National Park near Dolgellau and Barmouth. Part of a converted Victorian slate cutting mill, our B & B directly overlooks the beautiful Mawddach Estuary, serving up breathtaking views and big breakfasts in style. Wake up to stunning views of Snowdonia's Mawddach Estuary and mountains.

You can walk directly down to the water’s edge and Mawddach Trail (please be aware our track is fairly steep!). The flat cycle trail and foot path between Barmouth and Dolgellau is one of the most scenic stretches of the Wales coast- you may have seen it on BBC's Julia Bradbury Railway Walks programme. Bring your bike or hire one locally to explore the Mawddach Trail and pedal to the pub! We are licensed and serve local craft ales and nice wines.

We are proud to have been recommended in national media including Country Living, The Guardian, Telegraph and The Independent

Built in 1868 with thick stone walls and massive timber beams, the building was used by quarrymen to split rock into Wales' famous roof slates. The building is full of character and has been refurbished with a mix of custom made furniture, modern design classics, traditional Welsh materials and contemporary en suite facilities. But it's the views over the Mawddach Estuary and mountains that steal the show: watch the tide come in over breakfast, see the sun set over a drink on the terrace.

COVID update - breakfast is now being served to your door so you can enjoy eating at a table in the comfort of your own room. We are sorry but the communal lounge is not currently open.  You can still enjoy the wonderful views from our terrace over a drink.

Getting There

Ignore Sat Nav if using the postcode as it takes you a couple of miles too far to Morfa Mawddach railway station. Instead, turn off A470 Dolgellau bypass, and take A493 signposted Tywyn/Fairbourne. Approximately five miles from Dolgellau and one mile before Arthog village, look out for the second road traffic sign with the horse symbol on the left hand side, followed by a solitary post-box on the right. Continue for approximately 300 metres along a narrow stretch of road and look out for the Graig Wen entrance/sign on the right hand side on the brow of a slight hill.
