The list includes 25 mountains in Scotland, seven in England and eight in Wales, each of which has been described and illustrated in a souvenir supplement to mark the magazine’s birthday, with contributions by the best of Britain’s outdoor writers and photographers.

The highest mountains in Scotland and Wales, Ben Nevis and Snowdon, both feature – but not Scafell Pike which, after great debate, was pipped to the post by its neighbour, Sca Fell. The furthest north is Ben Loyal, the furthest west Ben More (Mull), the furthest east Kinder Scout and the furthest south Pen y Fan.

TGO Editor Emily Rodway said: “Over four decades, The Great Outdoors has established a reputation as the most authentic and authoritative magazine dedicated to British hillwalking. We were therefore able to call on some of the country’s greatest outdoor writers and photographers to create a beautiful tribute to Britain’s finest mountains in celebration of our 40th birthday.

“There was plenty of lively debate as we drew together our final list of 40 mountains, but it was worth the effort, and putting the supplement together was enormous fun.”

The Great Outdoors has had just four editors in its 40-year history, and Emily’s three predecessors – Roger Smith, Peter Evans and Cameron McNeish – all contributed memories from their time on TGO to the 40th birthday issue of the magazine, which comes bagged with the Britain’s 40 Finest Mountains supplement and is published today.
