Plumpton Rocks is a man-made lake and surrounding pleasure gardens 3.5 miles (5.6 km) south-east of Harrogate in North Yorkshire, England, near the village of Plompton.

It closed again in October 2019 to bring the lake dam up to standard for the Reservoirs Act 1975, and reopened in September 2022.

[3] The gardens were designed by Daniel Lascelles in the 1750s against a backdrop of towering millstone grit rocks that have been eroded by the wind.

The lake was extended by a dam built by John Carr, architect of Plompton Hall and Harewood House.

[1] J. M. W. Turner was commissioned by Edward Lascelles, 1st Earl of Harewood, to produce two paintings of the lake and rocks.
