Climbing Ben Nevis: The Mountain Path, Timings and Safety

Home / Guides / Ben Nevis

At 1,345 m, Ben Nevis is the highest mountain in the British Isles. The Mountain Path from Glen Nevis is a long, rough day that many people attempt, and the weather on top is often very different from the glen. This guide covers the route, the timings, and the navigation and weather points that matter most.

The Mountain Path

The usual route starts in Glen Nevis and follows the Mountain Path, sometimes called the Pony Track or Tourist Path. Figures differ between sources, but it is roughly:

• Distance: about 16 to 17.7 km (around 10 to 11 miles) for the round trip.
• Ascent: around 1,300 to 1,350 m, from near sea level.
• Time: the Ben Nevis Visitor Centre's safety sheet says normally 6 to 8 hours, and another guide gives 7 to 9 hours for most walkers. Fast walkers can be quicker, but plan for a full day.

It is a rough, stony path for most of the way. Do not underestimate the height gain, and allow time for the descent, which is hard on the knees.

Weather and the summit

The weather on the summit is often far worse than in Glen Nevis. One guide notes that Ben Nevis averages only 14 clear summit days a year, and walkers report the summit is cold even in summer. Pack for all conditions, including warm layers, hat and gloves and waterproofs, whatever the valley forecast says. Check the Met Office mountain forecast, and ask at the Ben Nevis Visitor Centre if you do not understand it.

Navigation and the cliffs

The path to the top passes within a short distance of the biggest cliffs on the UK mainland. In mist, this is the danger. The safe route off the summit plateau is a dog-leg around the top of Gardyloo Gully, a precipitous drop only about 20 m from the main path. Cairns mark the turns on the way down, but they can be buried in snow after a heavy winter.

• Carry a map and compass and know how to use them. The Visitor Centre advises this, and says not to rely on mobile phone reception.
• Follow the route guidance before you go. Bearings for the summit descent are published by the Mountaineering Council of Scotland and the BMC. We have not given bearings here because published figures differ, so check a current, reliable source and your map.
• If you become disorientated, consider turning back. This is the Mountaineering Council of Scotland's advice.

Our map and compass guide covers the basics.

Winter

In winter, Ben Nevis is a serious mountaineering day. Cornices can hide the edges of the gullies, snow can bury the cairns, and some gullies carry an avalanche risk. Precise navigation is essential to avoid falling through a cornice. Winter conditions need winter skills, the right equipment, and current avalanche and weather information. If you do not have them, do not go, or go with a qualified guide.

What to carry

Everything in our hillwalking safety guide applies, and more. For a long, cold day, take warm layers (see what to wear), a head torch, a storm shelter, food and water, and a charged phone and power bank. Good boots matter on this rough, stony path, such as the Scarpa Terra GTX.

Ben Nevis and the National Three Peaks

Ben Nevis is usually the first peak of the National Three Peaks Challenge, followed by Scafell Pike and Snowdon. Because the walk takes most of a day, the whole challenge is mostly about timing and driving. See our guides to Scafell Pike and Snowdon. Conservation groups, including the John Muir Trust, have raised concerns about damage and disruption caused by organised Three Peaks events, so follow local guidance if you are organising one.

Quick answers

How long does it take to climb Ben Nevis?

Normally 6 to 8 hours for the round trip according to the Ben Nevis Visitor Centre, and 7 to 9 hours for many walkers. Plan for a full day.

How far is the Ben Nevis Mountain Path?

Roughly 16 to 17.7 km for the round trip, with about 1,300 to 1,350 m of climbing.

Is Ben Nevis dangerous?

The path is well used, but the weather is often poor, and the path passes near large cliffs. Navigation in mist is the main risk, and winter conditions are a serious mountaineering day.

Do I need a map and compass?

Yes. The Visitor Centre advises it and says not to rely on mobile signal.
