Overview

From Mortimer, the route follows a clear stream, then onward to the amphitheatre and the 2.5km of Roman walls surrounding the 107-acre site of the Roman town of Calleva with the twelfth-century church at its entrance. Recent clearance of foliage has improved the view of the amphitheatre and the wall.

The afternoon route is mainly through woods of Scots pine, and commons of gorse and birch trees. Aldermaston, the final destination, is reached over the River Kennet and the Kennet and Avon canal.
