Sandscale Haws is included under virtually every conservation convention going, from Site of Special Scientific Interest (SSSI) to RAMSAR site of international importance.


Its beach-fringed dunes jut into the Duddon Estuary opposite the northern tip of Walney Island. Managed by the National Trust, these ever-shifting acres are home to a fifth of Britain’s natterjack toads, countless butterfly species and myriad wildflowers, while the estuary feeds immense numbers of wading birds.

Enchanting views draw the eye to Wordsworth’s beloved Dunnerdale Fells and across to shapely Black Combe, least-known of Lakeland’s peaks.

Dunes and slacks

The sandhills are in a constant state of flux, moulded by wind and storm surges and anchored by marram grass and ground willow. Unusually, the Haws is a zone of accretion – the sandhills are growing in size. Once ground vegetation secures the low dunes, growth gradually continues and the sheltered dune slacks encourage thicker vegetation.

Between April and June, a cacophonous soundtrack accompanies sunset. This is the mating call of the male natterjack toad, a nationally rare species that lives among the freshwater ponds in the dunes; there are two pools beside the car park boardwalk. A yellow stripe along its backbone distinguishes it from the common toad, as does its memorable scrambling gait.

Apart from natterjacks, the Haws are home to the complete range of British amphibians, including smooth, palmate and great crested newts. Time spent staring into the dune slack pools should prove fruitful; look too for herons and little egrets feeding on this bounty. In sheltered spots common lizards draw vigour from the sunshine before feeding on their insect prey.

Lepidopterists will enjoy a bounty of species at Sandscale. Clouds of common blues feed here, as does the dingy skipper; silvery grayling, wall brown and dark green fritillary flit silently through the sandhills throughout the summer. Dragonflies, such as the emperor and four-spotted chaser, hunt among the ponds and marshes.

Over 600 plant species have been recorded across this 700-acre reserve. In the dune slacks, grass of parnassus and round-leaved wintergreen shine white; while bee, Northern marsh and coralroot orchids are dune specialists. Low-growing sea holly is common here, and delicate dune pansy glows purple across the area.

Throughout the year, the reserve’s bounding mudflats and sandbanks offer a banquet to a host of species; ringed plovers, terns, turnstones and oystercatchers are the summertime stars, while skylarks, whitethroats and pipits add cheerful song. Raptors include peregrines, buzzards and hen harriers. The winter months are the best time to see birds in big numbers, with 70,000 knots, redshanks and dunlins feeding amid small flocks of sanderlings.
