Ilkley is a spa town and civil parish in West Yorkshire, in the north of England. Ilkley civil parish includes the adjacent village of Ben Rhydding and is a ward within the metropolitan borough of Bradford. Approximately 12 miles (19 km) north of Bradford, the town lies mainly on the south bank of the River Wharfe in Wharfedale, one of the Yorkshire Dales. The parish has a population of 13,828 (census 2001).
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.”
