Oh I do like to be beside the seaside
Innocent Path, then through countryside (on an off-road path) and a back road to Musselburgh, wee gander at the harbour, then along to Porty and onto the Prom.
Back inland into my back yard, the Figgate Park!
Highlight of this section, however, are the Craigentinny Marbles. If you haven't seen them before be prepared to be stunned (as much by the random location as anything else).
Shortcut available by turning left after crossing the railway line and cutting out the loop to Musselburgh. Shortens by about 2.5 miles.
