Taff's Well

Taff's Well (Welsh: Ffynnon Taf) is a semi-rural village, community and electoral ward located at the south easterly tip of Rhondda Cynon Taf, 6 miles (9.7 km) to the north of Cardiff, the capital city of Wales. Known locally as the 'Gates to the Valleys', it is separated from Gwaelod-y-Garth by the River Taff. Taff's Well is distinguished because it contains the only thermal spring in Wales. The tepid water is thought to rise along a fault-line from the Carboniferous Limestone, in somewhat similar manner to the warm springs at Bristol and Bath. Various religious groups regard it as a spiritual site.

The Garth Mountain overlooks the village and was the inspiration for the fictional "Ffynnon Garw", featured in the book and film The Englishman who Went up a Hill but Came down a Mountain.
