An unusually well-kept and picturesque park running down from the open skies of Blackheath to the National Maritime Museum. From the top of the short, but steep hill, next to the Royal Observatory, there is an arresting view of the elegant gold-crested towers of the Royal Naval College backed by the Thames and then the glistening skyscrapers of Canary Wharf, London's tallest buildings. Elsewhere in this Royal Park, the grass is immaculate, the landscape gardens tasteful, the benches grand and the large children's playground well-equipped. Even the cafe, near the Observatory, is a notch above the usual park fuel-stop. 9/10
