This local nature reserve in the Moseley area of Birmingham is a nice place for an easy stroll in the city. There's ancient woodland, ponds and lots of wildlife to look out for at the site. The area is also notable as being Tolkien's inspiration for the ancient forests in the famous The Lord of the Rings and The Hobbit books.
Just to the east you can visit Sarehole Mill. There's some fine trails along the River Cole around the 16th century mill which is notable as Birmingham's last surviving water mill. You can also pick up the River Cole Valley Walk and visit Kingfisher Country Park at the mill.
To the south is Swanshurst Park where there's a short circular footpath around a pretty lake.
