Saltburn Gill is a 52 acres SSSI woodland nature reserve, with the stream of the same name running along its western boundary.  The reserve is a good example of the type of woodland that would once have covered East Cleveland with a mixture of Oak and Ash, with a Hazel and Holly understorey.  Prior to the arrival of Dutch elm disease Wych Elm would also have been a common tree but has been replaced by Sycamore, which has to be managed.  A public footpath runs through the entire length of the reserve and provides good opportunities to see all that the reserve has to offer.
