What is the National Three Peaks Challenge?
The National Three Peaks Challenge is a classic British mountaineering challenge: climb the highest peak of Scotland (Ben Nevis, 1,345 m), England (Scafell Pike, 978 m) and Wales (Yr Wyddfa — also called Snowdon, 1,085 m). Tradition says you do all three in 24 hours, but many walkers spread it over a weekend or a full week.
Cims, sempre amunt is an app that makes tracking the Three Peaks — and every other list you care about — simple. Mark each summit as done, add a photo and date, and watch your progress grow. You'll also find dozens of other challenges across the UK, Europe and beyond, all in the same place.

Frequently asked questions
What exactly is the National Three Peaks Challenge?
It's a popular British mountaineering challenge: summit the highest peak of each of the three nations — Ben Nevis (Scotland, 1,345 m), Yr Wyddfa / Snowdon (Wales, 1,085 m) and Scafell Pike (England, 978 m). Classically attempted within 24 hours including travel, but plenty of people take a weekend or longer.
Is this app officially endorsed by the National Trust or any mountain authority?
No. Cims, sempre amunt is an independent passion project with no affiliation to the National Trust, John Muir Trust, Snowdonia National Park or any other organisation. If you want official recognition or a certificate, look at charity-run Three Peaks events.
How much does the app cost?
The app is completely free. No subscriptions, no ads, no paywalls. The project is supported by voluntary donations from users who want to help.
Which platforms is it available on?
iOS (iPhone and iPad) and Android. Download it from the App Store or Google Play.
Can I log Three Peaks I did before installing the app?
Yes. In each summit form you can set the real date you climbed it and add a photo if you have one. Your progress recalculates automatically.
What other UK challenges can I track?
Beyond the National Three Peaks you can follow the Catalan 100 Cims, French Alps 4000ers, Montes Gallegos and many more — new challenges are added regularly. Follow as many as you want; the same ascent counts for every challenge that contains it.
How are summits validated?
The app runs on trust: you log your own ascents with a photo and date. There's no mandatory GPS check or external validation. It's a personal tracking tool, not an official competition.
Cims, sempre amunt is not affiliated with or endorsed by any mountain authority, national park or federation.
