Hack Fall Wood
Hack Fall Wood, otherwise known as Hackfall, is a Site of Special Scientific Interest, or SSSI, of , lying north-east of the village of Grewelthorpe, North Yorkshire, England. During the 18th century it was landscaped in the picturesque style by landowner William Aislabie, who created views by engineering streams and pools, planting trees and building follies. Turner and Gilpin painted it, and pictures of it featured on Catherine the Great's 1773 Wedgwood dinner service. Some 19th century writers called it "one of the most beautiful woods in the country."

Following 20th century clear-felling and natural regeneration of trees, the Woodland Trust purchased the property in 1989. The site was designated as an SSSI in the same year. Together with the Hackfall Trust and the Landmark Trust, the Woodland Trust restored footpaths, conserved the remaining follies and managed the wildlife habitat according to its SSSI status.

The woodland supports varied wildlife, including many birds, animals and flowering plants, plus more than 200 species of liverworts and mosses, and two rare creatures: the beetle "Platycis minutus" and the lemon slug, which lives only in ancient woodland. The site is now listed as a Conservation Area, and as Ancient Semi-Natural Woodland (ASNW). The woodland is open to the public and has many summer visitors, although the only public facility is a car park.
