I found this and thought it was quite good. Obviously an OS Explorer in your pocket does the job but quite good non the less. Basically it's an interactive map of all the rights of way in Surrey. A bit clunky but not bad.
If you go [url=http://www.surreycc.gov.uk/sccwebsite/sccwspages.nsf/LookupWebPagesByTITLE_RTF/Rights+of+Way+interactive+map?opendocument]here[/url] and click on interactive Rights of Way map it will take you there, there's also a cribsheet to download in pdf but it's pretty intuitive.
