Ilkley is a spa town and civil parish in the City of Bradford in West Yorkshire, in Northern England. Historically part of the West Riding of Yorkshire, Ilkley civil parish includes the adjacent village of Ben Rhydding and is a ward within the City of Bradford. Approximately 12 miles north of Bradford and 17 miles north-west of Leeds, the town lies mainly on the south bank of the River Wharfe in Wharfedale, one of the Yorkshire Dales.
Ilkley's spa town heritage and surrounding countryside make tourism an important local industry. The town centre is characterised by Victorian architecture, wide streets and floral displays. Ilkley Moor, to the south of the town, is the subject of a folk song, often described as the unofficial anthem of Yorkshire, "On Ilkla Moor Baht 'at". The song's words are written in Yorkshire dialect, its title translated as "On Ilkley Moor without a hat."
