Getting Between Stops
Heathrow to central London takes 15 minutes on the Heathrow Express to Paddington, with the Elizabeth line slower and cheaper. In London, tap a contactless card or phone on the Tube and buses.
London King's Cross to York is about two hours. York to Windermere takes about three to three and a half hours with one or two changes. Oxenholme, the main-line station for the Lake District, to Edinburgh Waverley takes roughly two and a half hours. Booking each leg ahead gets the best fares and seat reservations.
In the Lake District, buses link Windermere, Ambleside, Grasmere and Keswick. Windermere Lake Cruises connect towns around the lake. If you want quieter valleys, rent a car for a single day, avoiding the steep Hardknott and Wrynose passes if you are nervous drivers. Edinburgh's center is compact and hilly, so walk and use the tram for the airport.
Where to Stay
In London, Claridge's in Mayfair is the grande dame, with Art Deco corridors and a famous afternoon tea. The Savoy has river-view rooms, The Goring in Belgravia is family-owned and Ham Yard Hotel in Soho puts the theaters at your door.
In York, Grays Court is a historic house behind the Minster with its own stretch of city wall in the garden. The Grand, York has a spa in the former railway headquarters near the station. Middlethorpe Hall suits couples who want gardens and quiet.
In the Lake District, Gilpin Hotel & Lake House near Bowness has garden suites with private hot tubs and a Michelin-starred restaurant. The Forest Side in Grasmere and Another Place, The Lake on Ullswater are strong alternatives.
In Edinburgh, The Balmoral on Princes Street has castle-view rooms and a spa. Prestonfield House is a baroque mansion at the foot of Arthur's Seat, ten minutes from the center by taxi.
When to Go
May to September is the best window. Evenings are long, with twilight in Edinburgh lasting past 10 p.m. in June. The Lake District valleys are green with lambs in the fields. June and September are the sweet spots, with September often drier and calmer in the Lakes.
July and August are busiest. Roads and parking around Windermere and Bowness fill early, York's weekends are crowded with day-trippers and hotel prices peak. August is a special case in Edinburgh, when the International Festival and the Fringe fill the city with shows and hotels sell out far ahead at much higher rates.
December brings Christmas markets in York and Edinburgh and Hogmanay at the end of the year, though days are short and the Lakes are raw. January to March is cheapest and quietest. In any month, expect rain in the Lake District, one of the wettest parts of England.
Budget and Booking
Expect roughly $300–850 a night for two in boutique to luxury hotels, with London at the top of that range or above it and York the gentlest. A Lake District suite with a private hot tub and dinner can cost well beyond the top of the range. All figures are approximate and rise in August, on York race days and on December weekends.
Book in this order: Lake District hotel and restaurant, since the best tables sell out weeks or months ahead, especially on Fridays and Saturdays. Then Edinburgh hotels, especially for summer. Then train tickets as soon as fares open for your dates.
Buy timed tickets for York Minster, Dove Cottage and Hill Top online in busy months. Many London restaurants add a 12.5% service charge automatically, so read the bill before you tip. Scottish banknotes are fine in Scotland but occasionally refused in England, which matters little on this route since Edinburgh is last.
Weather and Packing
Pack for rain everywhere and treat sunny days as a bonus. A waterproof jacket, layers and sturdy walking shoes or boots cover the Lake District paths, York's uneven city walls and Edinburgh's steep closes. Cobbles are hard on heels for either of you.
On the fells, check the mountain forecast before any serious hike and tell your hotel where you are going. Helvellyn via Striding Edge is thrilling in good weather and dangerous in poor conditions, so attempt it only with experience and a clear forecast. The wind on Arthur's Seat can also be fierce.
In London, keep phones in a pocket on busy streets, where snatch thefts by people on bikes are the most common crime against visitors. Dress codes are relaxed, except at The Ritz, where jackets are expected for men at afternoon tea. One smarter outfit each covers tasting-menu dinners and grand hotel bars. Pack light for the trains.
Make It Shorter or Longer
With nine days, skip York and go from London to the Lake District by train from Euston to Oxenholme in about two and three-quarter hours. Keep three nights each in the Lakes and Edinburgh.
With 14 days, add two nights in the Scottish Highlands after Edinburgh. Rent a car at Edinburgh Airport and drive through Glencoe to Fort William, or take the train to Inverness. A longer version adds the Isle of Skye for three more nights.
With 16 days, add the Cotswolds or Bath after London before heading north. Bath is about an hour and a half from Paddington by train, with a rooftop thermal pool that makes a lovely first slow stop.
Keep at least three nights in the Lake District whatever you change. It is the only countryside stop on the route. A single rainy day can take one of your walks away.
