This gentle walk along the East Lothian coast explores contrasting sedimentary rocks including limestone that is stacked with fossils and contains rich evidence of the conditions of equatorial Scotland around 330 million years ago.
The walk starts in a volcano, and after we’ve seen the volcanic rocks which help create Dunbar’s harbour, we will walk past layers of Devonian red sandstone which surround the volcanic vents. Further along the shore we cross a few small faults, and come to a variety of younger sedimentary rocks from the Carboniferous Period. These rocks include limestone with plenty of fossils, best seen between White Sands and Barns Ness.
