Idyllic Ilkley Caps Grass-Court Season The ATP Challenger Tour grass-court swing concludes with the Ilkley Trophy at the 143-year-old Ilkley Lawn Tennis & Squash Club. Arguably one of the most picturesque venues on the Challenger circuit, the tournament is nestled adjacent to the idyllic Ilkley Moor, Cow & Calf Rocks and River Wharfe. With the rocks perched atop the moor, the expanse is 402 m (1,319 ft) above sea level and overlooks the town and surrounding countryside.
