The glorious white sand beach of Pentle Bay on Tresco is fringed on the landward side by gentle dunes.
Among the marram grasses are unexpected patches of wild flowers and ferns.
Above the dunes is a coastal path
bordered by more wild flowers and grasses.
The long sandy beach of Camber Sands is bordered on the landward side by picturesque sand dunes. The dunes are covered with marram grass that has a deep root system to hold the grass in place. Traditional chestnut fences help sand build up and check coastal erosion.
