A short walk along the Firth of Forth, taking in some sandy beaches, a range of sedimentary rocks from the Carboniferous, an impressive dolerite dyke and one the Lothian’s most famous glacial erratic boulders, The Johnny Moat Stone.

THE WALK: This perhaps isn’t the most picturesque part of Scotland’s coast, but it is packed full of interest with a range of sedimentary layers exposed along the shore, and good views along the coastline. From Prestonpans we will follow the John Muir Way and other coastal footpaths, with occasional forays onto the rocky shore. I have classified this as a moderate walk: we will be walking on the beach and rough paths, where it may be rough or slippery underfoot at times. It may be wet, windy or cold. Come equipped with strong footwear and waterproof clothing.

MEETING POINT & ROUTE: Meet at the John Muir Way car park on the shore opposite the Prestongrange Museum. Grid reference NT 370 738. From the end of the walk, you can catch Lothian Bus service 26 back to the start point. Grid reference: NT370737 | Nearest Postcode: EH32 9SA | What3Words: august.slug.chimp | Route Map.
