Celyn Bach is a pod. It's on a working farm in Abertridwr, just outside Llanwddyn village. It's remote. The field it's in is big and enclosed.
It's a 4 Star place, which means it's comfortable and well-equipped. It sleeps four, but that's in one room with a double bed and a double sofa bed. It's really best for a couple, maybe with two kids. There's one en-suite shower room.
The layout is all one studio space. There's a kitchenette with the basics. You get bedding and towels. Outside there's a raised concrete deck to sit on. The views are over fields. It's very quiet.
You're right by Lake Vyrnwy. It's a reservoir built to supply Liverpool. It's now a big RSPB reserve. You can walk, cycle, or hire a boat there. The RSPB site has maps and details.
Oswestry is about twenty minutes drive for supermarkets and shops. The Snowdonia National Park authority site is useful for wider area planning. The Visit Wales site has general information.
Facilities included: parking, WiFi, bike storage, all utilities. One well-behaved dog is welcome. It's glamping, so it's unique.
There's another pod on the farm called Cae Bitfel. You can book both together if you need two separate spaces.
