Hand-picked by the experts at Trail magazine, the Trail 100 is a collection of the 100 UK peaks all hikers, hillwalkers, and backpackers must climb at least once in their lifetime.
The Trail 100 isn’t just about climbing the UK's highest mountains (although many of them are), it’s about climbing a curated list of the finest summits our islands have to offer – and having the time of your life while doing it.
The challenge could take months, years, or even decades to complete, and by the time you finish it you’ll have ticked off every major name on your mountain bucket list.
How is it different from other mountain tick lists?
Unlike other mountain-bagging lists, the Trail 100 isn’t restricted by location, height, or guidebook. Instead, it’s a definitive collection of the 100 hills and mountains peaks we believe every hillwalker and hiker should climb in their lifetime. Put simply, we believe these are the very best 100 peaks in the UK.
Who chose the Trail 100 mountains?
The Trail 100 list has been hand-picked by the experts at Trail magazine. With over 30 years of experience walking and climbing in the UK’s greatest hills and mountains, the Trail team has carefully collated a selection of peaks of all shapes and sizes that are all ‘must-do’ summits.
Where are the Trail 100 peaks located?
All over the UK! The Trail 100 will take you from the mighty summits of Scotland to the limestone peaks of the Yorkshire Dales and the gritstone edges of the Peak District.
You’ll cross razor-sharp Welsh ridges, lose yourself in Lakeland valleys, explore the weird tors of Dartmoor, discover the dazzling green beauty of the Brecon Beacons, and head across the Irish Sea to the Mourne Mountains. Plus much, much more.
How hard is the Trail 100 challenge?
The beauty of the Trail 100 list is that it’s a real mixed bag of peaks. There are easy-going hands-in-pocket strolls, gnarly mountain ascents (including at least one you'll want ropes for!), and everything in between.
There’s no obligation to climb them all, of course. If you like, you can just use the list as inspiration, picking and choosing whichever mountains most appeal.
How long does the Trail 100 challenge take?
This is the real beauty of the Trail 100, because the amount of time you take to complete the challenge is totally down to you.
One of the handful of people we know to have hit every summit on the list is Trail magazine's long-serving photographer Tom Bailey. And considering the fact Tom spends every other week in the mountains for work, it still took him the best part of two decades to complete.
The best way to look at the Trail 100 is as a bucket list rather than a challenge. Even if it takes most of your life to tag every mountain summit on the list, what a life you'll have lived!
