Wednesday 12th October, 10:00 am to 1:00 pm. The walk is run as part of the Northumberland Coast AONB series of geo-diversity walks.
Walk summary: This section of the coast provides some of the most extensive exposures of the Whin Sill, where the surface of the sill slopes down to the sea along a curve of coastline which leads to the romantic ruins of Dunstanburgh Castle, yet another historic piece of military hardware which has exploited the Whin Sill's tendancy to form high ground. This walk winds out over the whin heughs to the castle giving an opportunity to explore not only the igneous origins of the sill and what it can tell us, but also to examine the relationship between these heughs and mankind as well as its curious ecology.
Beyond Dunstanburgh Castle we will also explore Greymare rocks, where layers of limestone have been ruched as if made of cloth, telling a story of the enormous forces which have operated to fold and tear the rocks here.
Where do we meet? We meet by the Tourist Information Centre at the entrance to the car park in Craster. Grid reference NU 256 198
Please be warned that parking can be difficult, and if you are driving it is worth arriving in plenty of time. There is also an excellent bus service which makes for a more relaxed way of getting to Craster (and you get a great view from the top deck!).
How long is the walk? This walk will be approximately 4km, there will be some scrambling across rocks which will be slippery if wet. Strong boots are recommended and some may find walking poles helpful.
What else do I need to know? Full details will be sent out on email to everyone who books.
