Frith Wood nature reserve is a wonderful ancient beech wood that straddles the ridge overlooking the Painswick and Slad Valley's near Stroud. There are a number of footpaths that go through the reserve. The wood is home to rare plants such as wood barley, white helleborine and yellow bird's nest. In spring there is a lovely display of bluebells and wild garlic. Although small and rarely seen a very rare snail called Ena montana has been recorded here. The nature reserve is part of a larger SSSI that includes Bull's Cross and Juniper Hill.
