There are a number of long distance hiking trails to the south of us in England. We have done some bits and bobs of these over a period of about 5 weeks and overall had a great time.
Coast to Coast Trail about 2 weeks across northern England in 2015 and 2016 through the Lake District, Yorkshire Dales and North York Moors National Parks.
South West Coast path in Cornwall. We have hiked 2 weeks of this trail in 2019 and 2020 out of about 6 weeks in total.
Cumbria Way crossing the Lake District National Park in 2022 for about 70-80 miles, north to south between Carlisle and Ulverston on Morecambe Bay.
