A591 road England

 The A591 is a prominent thoroughfare located in Cumbria, a region in northwestern England, that traverses almost the entirety of Lake District National Park. According to a survey conducted in 2009 by satellite navigation company Garmin, the segment of the road between Windermere and Keswick was voted as the most popular route in the entire United Kingdom. Furthermore, car rental firm Avis determined that the 29.8-mile stretch from Kendal to Keswick has the highest driving quality in the UK, based on their specially designed driving ratio.

The journey begins at the southernmost point of the road, which is situated 3.5 miles (5.6 km) northwest of junction 36 of the M6 motorway, at Brettargh Holt roundabout, where it meets the A590 road (54.2746°N 2.7605°W), close to the stunning Sizergh Castle. After bypassing the town of Kendal as a dual carriageway, which cost £1.9 million to construct and covers 3 miles (4.8 km), it transforms into a busy single-carriageway road upon entering the Lake District. Following the north-eastern bank of Windermere, the road bypasses the town of Windermere and traverses the heart of Ambleside, then follows the northern side of Rydal Water, passes through White Moss Common, follows the eastern edge of Grasmere and eventually past the village of Grasmere. Continuing over Dunmail Raise and along the eastern edge of Thirlmere, the road shortly leads to the town of Keswick, where it meets the A66 road at a grade-separated junction.

Subsequently, the A591 is temporarily replaced by the A66, which takes drivers westward for 2.2 km, to a roundabout where the A591 resumes and heads in a roughly northwesterly direction, boasting magnificent views over Bassenthwaite Lake. The journey comes to an end at the village of Bothel, where it meets the A595 road (54.7357°N 3.2733°W). The section of the road from Bothel to Keswick is particularly narrow and contains many acute bends, requiring extra caution when driving.

On December 5, 2015, the road was severely damaged during Storm Desmond, which resulted in a part of it being washed away at Dunmail Raise and a landslide adjacent to Thirlmere. The closed section between Grasmere and Legburthwaite was reopened on May 11, 2016. During the road closure, a new tarmac path for walkers, cyclists, and horseriders was constructed to the west of the road at Dunmail Raise.
