Walton and Ivythorn Hills (grid reference ST475346) is a 34.9 hectare (86.1 acre) biological Site of Special Scientific Interest near Street at the south-eastern end of the Polden Hills in Somerset, notified in 1953. Walton Hill is south of the village of Walton, and Ivythorn Hill (sometimes spelled Ivy Thorn Hill) is south of Street.
This site is owned and managed by the National Trust.
Walton and Ivythorn Hills support a complex mosaic of semi-natural habitats which includes unimproved calcareous grassland, dense and scattered scrub and broadleaved woodland. Structural diversity within the habitats, together with the extensive areas of sheltered wood-edge and scrub-edge margins provide ideal conditions for many species of invertebrate. Butterflies, Leafhoppers, Spiders and Soldier Flies are particularly well represented. The Great Green Bush Cricket (Tettigonia viridissima) is also of interest.
There is some evidence of the remains of ancient earthworks on Walton Hill.
The shoe manufacturer C&J Clark, through the Society of Friends, had a small sanatorium and convalescent home on Ivythorn Hill overlooking Street. In 1931, this chalet style building was leased to the Youth Hostel Association and became the first youth hostel in Somerset. It is still used for this purpose.
