good links to the description of the path:
http://www.southdownsway.co.uk/sdw_seaford_eastbourne.htmlhttp://www.sevensisters.org.uk/page50.html took a train to Brighton (wanted my mom to see it). then bus 12 to Seaford (2.5 pounds. 40 min)
then walk by the sea. all is pretty clear
initial plan was to walk all the way to Eastbourne, but it was much more that we expected
so we only walked a bit (in red), whereas initial plan was red+blue
then we took bus 12 to Eastbourne and then train back to London
unfortunately the turn left is necessary - there is a river and no bridge so one has to take a detour away from the sea to cross it
