With huge views taking in four countries – on a good day – the Isle of Man’s fells and peaks offer walkers a true sense of untapped adventure

There’s a magic pool in Ballaglass Glen. Scored deep into the ancient flagstone, amid the oak, larch and beech, it’s fed by a cascade, spangled with shafts of sunlight and probably hides mooinjer veggey – Manx Gaelic for the mythical “little people”. As I slid my tired legs into the numbingly cold water, I felt a sense of exhilaration.

It had been the most glorious of days, tackling my first of the island’s eight new summit walks; between them, these medium-to-challenging routes conquer 25 of the Isle of Man’s 300-metre-plus peaks. The island might not be big – just 33 miles by 13 miles at its longest and widest points – but it has plenty of rugged terrain and satisfying highs.
