Square du Vert-Galant Paris

Chestnut, yew, black walnut and weeping willow trees grace this picturesque park at the westernmost tip of the Île de la Cité, along with migratory birds including mute swans, pochard and tufted ducks, black-headed gulls and wagtails. Sitting at the islands' original level, 7m below their current height, the waterside park is reached by stairs leading down from the Pont Neuf. It's romantic at any time of day, but especially so in the evening as the sun sets over the river.
