The White Cliffs of Dover are a symbol of Britain, standing up to 110 m high along the Kent coast and composed of brilliant white chalk streaked with flint. Facing the English Channel, they have greeted travellers for millennia and played a strategic role in wars. The National Trust manages walking trails along the cliff tops, offering views of passing ships and the French coast on clear days. Rare plants like sea kale and chalk grassland wildflowers thrive on the cliffs, which are home to nesting fulmars, kittiwakes and peregrine falcons.
