About the reserve

A compact reserve of ancient Yew woodland on limestone pavement overlooking  the Vale of Clwyd.    The site forms part of the larger Eyarth Woods and Rocks Site of Special Scientific Interest designated in 1972. The site is particularly notable for being one of three sites in Britain for the limestone woundwort Stachys alpina and it is the only yew Taxus baccata woodland in Clwyd. A great place to visit in Spring to hear the dawn chorus, see stinking hellebore Helleborus foetidus, wild daffodils Narcissus pseudonarcissus and morels. In Summer you can find common spotted orchids Dactylorhiza fuchsii and Stachys alpina in the small disused limestone quarry grassland. Autumn brings earth star fungi Geastrum triplex  and bright pink spindle Euonymus europaea berries.
