Derwentwater
Derwentwater is one of the most celebrated lakes in the English Lake District, a body of water of extraordinary beauty lying just south of the market town of Keswick in Cumbria. Stretching roughly three miles in length and just over a mile in width, it is not the largest of Lakeland's waters but is widely regarded as among the most visually spectacular, sitting in a natural bowl ringed by dramatic fells that plunge to its shoreline. It is part of the Lake District National Park, a UNESCO World Heritage Site since 2017, and draws hundreds of thousands of visitors each year who come to walk its shores, row upon its surface, or simply stand and take in one of the most iconic landscapes in England.
The lake's history reaches deep into early medieval times. The name Derwentwater derives from the River Derwent, which both feeds and exits the lake, and the Celtic word for the river likely relates to the word for oak. The area was known to the Romans, who had a fort at nearby Keswick. The lake takes its other historical identity from the Radcliffe family, Earls of Derwentwater, Jacobite supporters who forfeited their estates after the failed rebellion of 1715 — the last Earl, James Radcliffe, was executed on Tower Hill in 1716. Their lands passed to the Greenwich Hospital Commissioners and eventually to the National Trust, which now owns much of the lake's shoreline and manages it for public benefit. Local legend speaks of Lord's Island, one of several small islands on the lake, as the site of the Radcliffe family's manor house, and on still nights some say you can see phantom lights beneath the water, an effect in reality caused by escaping natural gases from the lakebed.
Those islands are one of Derwentwater's most enchanting features. Derwent Isle, the largest, was once home to a community of German miners brought over in Elizabethan times to work the copper mines in the surrounding fells, and it later became a private residence. Rampsholme, St Herbert's Island, and Lord's Island also dot the surface, each adding to the lake's fairy-tale character. St Herbert's Island is named for the seventh-century hermit saint and disciple of St Cuthbert who lived there in solitude, and Bede recorded that Herbert and Cuthbert asked God that they might die on the same day — a wish apparently granted in 685 AD. Pilgrims visited the island for centuries afterward.
Physically, Derwentwater has a quality that can feel almost cinematic. The surrounding fells — Skiddaw and Blencathra to the north, Catbells to the west, Maiden Moor and Walla Crag to the east — create a panoramic enclosure that changes character dramatically with the seasons and weather. On a calm morning the lake surface acts as a near-perfect mirror, reproducing the fells in trembling reflection. The sound of the place is defined by water — the lapping of the lake against its pebbly shores, the creak of rowing boats, the cry of oystercatchers and great crested grebes, and in autumn the honking of geese. The air carries the scent of damp stone and bracken, and the reed beds along the southern end rustle in even a gentle breeze.
The shoreline path that circumnavigates Derwentwater covers about ten miles and is one of the most walked routes in the Lake District, offering constantly changing perspectives as it passes through wooded bays, open meadows, and the marshy flats of Manesty Park. The western shore path through Brandlehow — the first land ever purchased by the National Trust in 1902 — and the ascent of Catbells (which rises steeply to 1,480 feet from the lake's western bank) are particular favourites. To the north, Friar's Crag is a celebrated viewpoint jutting into the lake where John Ruskin claimed to have had one of his earliest and most formative experiences of natural beauty; it is now commemorated with a memorial plaque. The Victorian critic and his legacy loom large in this part of the Lakes.
Keswick, just a short walk from the northern shore, provides all practical amenities — shops, restaurants, a theatre, the Keswick Museum, and the famous Pencil Museum, which celebrates the local graphite industry that once made this area industrially significant. The Keswick Launch company operates a seasonal ferry service calling at several landing stages around the lake, allowing visitors to combine a boat trip with fell walks without needing to return to the same starting point. The launch service typically runs from mid-March through to November, with reduced sailings in the shoulder seasons.
Visiting Derwentwater is rewarding at almost any time of year. Late spring brings wildflowers along the shoreline paths and the return of nesting birds to the reed beds. Autumn is perhaps the most dramatic season, when the surrounding woodland — particularly the oak and birch woods above Lodore at the southern end — turns copper and gold, and low cloud often settles between the fells to theatrical effect. Winter can see the lake partially freeze in hard frosts, a rare and eerie spectacle. Summer is undeniably the busiest period, when the lake car parks and Keswick itself become congested, but an early morning walk or an evening return to the shores when day visitors have left can restore a sense of peace and solitude.
Access to the lake is excellent. Keswick is served by regular bus services from Penrith, which has a mainline railway station on the West Coast Main Line. The A66 provides road access from the M6 motorway at Junction 40. Several car parks are available on the northern shore and in Keswick itself, though these fill quickly on summer weekends and bank holidays. The National Trust operates facilities at Borrowdale and the western shore. Much of the shoreline is accessible for walkers with limited mobility along the flatter northern stretches, and the launch service is accessible for most visitors, though the rugged fell paths are naturally more demanding terrain.
One fascinating but little-known fact about Derwentwater is that it is remarkably shallow — its average depth is only around 18 feet, making it one of the shallowest of the major Lakeland lakes, which contributes both to its tendency to freeze and to the unusual phenomenon of its floating islands. These buoyant masses of vegetation, root matter, and trapped gas occasionally detach from the lakebed and rise to the surface as genuine floating islands, a natural curiosity documented for centuries. The phenomenon has been observed and recorded by scientists and travellers since at least the eighteenth century and remains an occasional spectacle for lucky visitors today.
