Roanhead (sometimes spelled Ronhead) refers to the limestone outcrop of Roanhead Crag in Cumbria and the farmland behind it, but in recent years the term has been taken to mean the sandy beaches adjoining Sandscale Haws extending to Snab Point. The Irish Sea lies to the west of Roanhead, whilst the Duddon Estuary and Walney Channel are due north and south respectively. The beach is noted for its abundance of sand and strong, often dangerous coastal currents. Today the beach is a National Trust conservation area, and a two-mile stretch of the Cumbria Coastal Way runs through it.
Lampyris noctiluca (glow worm) have recently been recorded in the area between Roanhead crag and Sandscale Haws NNR.
There are 3 species of newt: palmate newt, smooth newt, and great crested newt. Otters have been recorded on the beach at Roanhead. The site hosts 4500 overwintering wading birds. Black backed gulls, black headed gulls and herring gulls roost in the crags. Plover (Birds of Conservation Concern red list) and Northern lapwing (red list) nest between Roanhead Crag and the shore. Between November and February common starling murmurations can be seen before the birds roost on the wet meadow at Sandscale Haws.
Other birds include: barn owl, Common kestrel (amber list), marsh harrier (amber list), sparrowhawk, oystercatcher (amber list), Eurasian curlew (red list), dunlin (red list), Red knot (amber list) sanderling (amber list), grey heron, skylark (red list), meadow pipit (amber list), snipe (amber list), turnstone (amber list), redshank (amber list), reed bunting (amber list), sedge warbler (amber list), little egret, mallard, teal wigeon, scaup, long tailed duck, great crested grebe, goldeneye, Common shelduck (amber list).

There are signs of shotholes on Roanhead Crag, indicating that, like Dunnerholme, it has been quarried for limestone at some time. There is a small limekiln near the National Trust depot, one of two on the estate.
Myles Kennedy leased the mining rights from Thomas Sandys in 1852.Lease of Ronhead mineral rights, Myles Sandys to CS Kennedy, December 1852, DD/Sa/9/71 at Lancashire Records Office, Preston . There may have been an earlier takenote but there is no sign of mining on the Roanhead estate on the 1850 OS map. The firm of Kennedy Brothers worked the iron mines until the last of the ore was taken from Nigel pit in July 1942Cumbria Records Office, Barrow, Roanhead mine reports, Z2919 The Nigel mine alone is said to have produced 11 million tons of ore.Geology and Haematite deposits of South Cumbria, The Geological Survey of Great Britain It was one of several deposits on the estate. The farmhouse was moved to its present site shortly after the discovery of the Nigel deposit in 1902.
The mines left a series of subsidence craters which are now flooded. Along with the ponds left by Park mines, they are currently managed as fishing ponds by Furness Fishing Association.
The mining system at Roanhead was top-slicing, which consists in the working of an orebody in horizontal slices, beginning at the top. Levels, for haulage, are established at proper intervals and, from these, raises are put up to the top of the orebody about every 50 ft. Starting at the tops of these raises drifts are run out and then, retreating toward the raise, the slice is worked back by breast stoping. The overburden or capping lying above the ore is supported on square sets or posts until a slice, or part of a slice, has been worked. The floor of the slice is then covered with slabs or plank and the supporting timbers are shot out and the capping is allowed to cave on to the timber floor.
"Access roads leading to the site are considered to be too narrow and quite inadequate to satisfactorily carry the traffic likely to be generated by a site of the scale envisaged by the application."
