Hazel Grove is a small narrow wooded ravine lying to the north of Saltburn. There is a beck running through the ravine known as Pit Hills Skell. The predominant trees in the wood are sycamores, Scots pines, Corsican pines and a few ash trees. The water draining down this valley from the surrounding hillsides creates a rather damp atmosphere in the woods, which has given rise to a very rich fern flora. This is one of the best sites in this area for Hart's Tongue Fern.
