Sheffield Park is a great landscaped garden created by Capability Brown in the 18th century.
I have spent many an enjoyable afternoon at Sheffield Park in every season, when my children were young and in pushchairs, but it will appeal to all.
In Spring there are displays of daffodils and later bluebells. 
Early summer and Rhododendrons and Azaleas come into their own giving the lake a magical feel.
In Autumn fabulous colours abound everywhere  and in winter the shapes look magnificent especially on frosty days.
