Those nice people at Google Maps have improved their images of this part of the UK. You can see some quite detailed views of yesterday’s walk here.
What you should see is an overview of the route I walked, starting at South Shields near the top, and ending at the bottom – look for the “A183” marker just by the River Wear. The walk was along the cliff-top path, well away from the road for most of the way. If you zoom in, you can see the path clearly. You can also see the lighthouse, which shows up clearly once you zoom in a bit.
