In an area renowned for its rich stock of ancient woodland, Penn Wood, at its very heart, stands out as one of the largest. The wood forms part of a mosaic of semi-natural ancient woodland and wood pasture, grassland and scrub, rich in wildlife and flora including at least 10 plants not commonly found in the county. It has a good bird population and a number of nationally scarce invertebrates.

Some of its older inhabitants include the remains of an ancient beech and a veteran oak, along with a scattering of trees dating back more than 200 years.

Penn Wood is well served with a network of paths, and a map can be downloaded here.
