The Outlying Fells of Lakeland is a book written by Alfred Wainwright, dealing with hills in and around the Lake District of England.
 It differs from Wainwright's "Pictorial Guides" in that each of its 56 chapters describes a walk, sometimes taking in several summits, rather than a single fell.
 This has caused some confusion on the part of authors attempting to prepare a definitive list of peaks.
 The Outlying Fells do not form part of the 214 hills generally accepted as making up the Wainwrights, but they are included in Category 2B of the Hill Walkers Register maintained by the Long Distance Walkers Association.
Newton Fell is a hill in the English Lake District near High Newton, south east of Newby Bridge, Cumbria.
 It lies to the north east of the A590 road.
 It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland".
 Wainwright describes two walks, to the summits he calls Newton Fell (north) at 780 ft and Newton Fell (south) or Dixon Heights at 585 ft .
 There are no public rights of way to either summit, and he states that the walks should be done "by courtesy of the owners and tenants".
Green Quarter Fell is an upland area in the east of the English Lake District, near Kentmere village, Cumbria.
 It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland".
 Wainwright's walk is an anticlockwise circuit from Kentmere, reaching the summit of Hollow Moor at 1394 ft and a nameless summit at 1370 ft and making a detour to admire the tarn of Skeggles Water.
 He says that the walk offers: ""... a perfectly-balanced and lovely view of upper Kentmere ... that cries aloud for a camera.""
Watch Hill is a small hill lying on the north-western fringe of the Lake District in England.
 The name Setmurthy Common is sometimes used (including by Alfred Wainwright in his book "The Outlying Fells of Lakeland") to refer to the area including the highest point, with "Watch Hill" describing the area to the west of the summit.
 It should not be confused with another Watch Hill some 19 km to the south-west, near Whitehaven, which is only 172 m (564 ft) high.
 The name "The Hay" is also used when referring to the area west of the summit.
The Crookdale Horseshoe is a group of hills on the eastern edge of the English Lake District, in Cumbria, west of the A6 road.
 They are the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland".
 Wainwright describes an anticlockwise walk starting along the valley of Crookdale Beck (which joins Borrow Beck before flowing into the River Lune) to reach Lord's Seat (one of several English summits of that name, and also known as High House Fell) at 1719 ft , and returning over Robin Hood at 1613 ft and High House Bank at 1627 ft .
 As he points out, the ridge forming the northern part of the "horseshoe" is described in his Wasdale Horseshoe chapter.
Woodland Fell is an upland area in the south of the English Lake District, south of Torver, Cumbria.
 It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland".
 Wainwright's route is a clockwise circuit from the hamlet of Woodland, and includes the summits of Yew Bank at 678 ft and Wool Knott at 730 ft , with Beacon Tarn (also visited on his Beacon Fell walk) between them.
 He describes the walk as: ""a connoisseur's piece, every step an uninhibited joy, every corner a delight.""
Flat Fell is a hill located on the edge of the English Lake District, standing at 272m.
 It is included in Alfred Wainwright's "Outlying Fells of Lakeland" book, sharing a chapter with Dent.
 Wainwright's clockwise route to the two summits starts at Wath Brow.
Alfred Wainwright ("A.W.") MBE (17 January 1907 – 20 January 1991) was a British fellwalker, guidebook author and illustrator.
 His seven-volume "Pictorial Guide to the Lakeland Fells", published between 1955 and 1966 and consisting entirely of reproductions of his manuscript, has become the standard reference work to 214 of the fells of the English Lake District.
 Among his 40-odd other books is the first guide to the Coast to Coast Walk, a 192-mile long-distance footpath devised by Wainwright which remains popular today.
Stainton Pike is a hill in the English Lake District, near Waberthwaite, Cumbria.
 It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland".
 It reaches 1550 ft and Wainwright's anticlockwise circuit also visits The Knott at 1071 ft (this latter not to be confused with its namesake The Knott in the eastern Lake District, or the other "outlying fell" near Stickle Pike, or Knott north of Skiddaw).
 The walk also passes the waterfall Rowantree Force and collection of ancient enclosures and hut circles known as Barnscar or City of Barnscar.
Irton Pike is a hill in the west of the English Lake District, near Santon Bridge, Cumbria.
 It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland".
 It reaches 751 ft and Wainwright's walk is an anticlockwise circuit from Irton Road station on the Ravenglass and Eskdale Railway, near Eskdale Green.
 He describes ""this tiny top"" as ""a near-perfect solace for reminscences of past happy days on the higher fells"", adding ""Climb Irton Pike while ye may!""
