Access Sculpture Trail was once a neglected part of the estate and was remodelled from 1986 by British sculptor Don Rankin. With other artists and trainees, he created an interweaving network of paths, plants and sculpture.

The trail can be exited at several points, but the pergola leading from the University car park provides a covered walkway into this area of YSP. Architectural and landscape features such as a stone circle, well and miniature aqueduct were constructed to shape and provide structure for the trail. Herbs, grasses and seasonal wild flowers await discovery.
