The Green Chain has some remarkable geological sites that reveal how this landscape evolved millennia ago. We've highlighted for your convenience 12 of the best below - from submerged forests and fossil beds with sharks teeth to spring wells fit for a king!
Each feature is also included in a fascinating audio trail. Starting conveniently at a nearby train station, the 12 mini 'Time Trails' bring to life the massive forces of nature that created them, and their importance in shaping economic activity and the lives of everyday people.
After completing the mini-trail, you can either retrace your steps back to the station or continue along the sign-posted Green Chain Walk for further explorations.
