Lovely Exeter, Devon’s ancient capital by the mighty River Exe, has plenty to see in its eighteen square miles. A network of buses can help you reach these sights and a bargain PlusBus ticket makes it easy to hop on and off the buses all day. See Roman walls and a medieval cathedral, a huge collection of movie memorabilia, and bird-haunted marshes by the wide Exe estuary. These are just a few of the adventures you can have by bus in Exeter.
