Celyn Brithion is a family-run caravan and camping site situated along the banks of the River Dovey (Dyfi) at Dinas Mawddwy, within Snowdonia National Park near Machynlleth.

The riverside setting is surrounded by green and purple mountains, ancient woodlands, and fast-flowing rivers. Tents, touring caravans, motorhomes, and trailer tents are all accommodated, with electric hook-ups, washrooms, toilets, and Wi-Fi on site.

Free fishing is available on the site boundary on the River Dovey. Dogs and small pets are welcome. The location serves as a strong base for outdoor pursuits, with walking, cycling, mountain biking, and birdwatching all close at hand.

Cader Idris and the Dovey Valley Trail are within easy reach, as are the coastal resorts of Barmouth and Aberdovey. A pub serving food and drink is a short walk away across the river.
