Tuesday 1st August: Meet at 14:00 by the Tourist Information Centre at the entrance to the car park in Craster NU 256 198
Please be warned that parking can be difficult at this time of year, 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 relxed way of getting to Craster (and you get a great view from the top deck!).
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 the rare whin-grassland habitat.
We will also have a look at Greymare rocks, an unusual wave shaped formation which tells a story of the enormous forces which have operated to fold and tear the rocks here.
The walk is run as part of the Northumberland Coast AONB series of geo-diversity walks. Just turn up. A donation will be asked for to cover the costs of the walk, an amount of £10 is recommended, however Northumbrian Earth would like to make these walks accessible to all, so a donation will be asked of whatever you can afford and/or you think the walk is worth.
This walk will be approximately 4km, there will be some scrambling across rocks which will be slippery if wet.
