The trail will introduce many of the rocks which make the Teesdale landscape so special and which make the dale a haven for rare and interesting plants. This trail is within Moor House-Upper Teesdale National Nature Reserve (NNR), an internationally important place for wildlife and earth heritage. The NNR is managed by Natural England in partnership with Raby and Strathmore Estates and local farmers. Do examine the rocks, minerals and plants you will see along the way but please do not collect them: leave them for others to enjoy.
