How to Plan a Walk up Ben Nevis: Routes, Maps and What to Expect
Share
At 1,345m (4,413ft), Ben Nevis is the highest mountain in the British Isles and one of the most climbed mountains in Scotland. Around 125,000 people attempt the summit each year. The most popular route is well-maintained and non-technical in summer conditions, but Ben Nevis is a serious mountain: the summit plateau is vast, navigation in mist is genuinely difficult, and the weather can deteriorate rapidly at any time of year. Good planning and a good map are not optional.

- Location: Fort William, Scottish Highlands (Lochaber)
- Standard route: The Mountain Track, also known as the Tourist Route or Pony Track
- Return distance: approximately 17km (10.6 miles)
- Total ascent: 1,344m
- Typical time: 7 to 9 hours return
- Recommended map scale: 1:25,000 for detailed navigation; 1:50,000 for general orientation
The Two Main Routes
The Mountain Track (Tourist Route)
The Mountain Track is the standard ascent route and the one most walkers use. It starts from the Ben Nevis Visitor Centre car park in Glen Nevis, just outside Fort William. The path is well-engineered for most of its length, climbing steadily through the lower glen before zigzagging up the broad south-western shoulder of the mountain to the summit plateau.
The route passes Lochan Meall an t-Suidhe, known informally as the Halfway Lochan, at around 570m. This is a useful waypoint and a natural place to reassess conditions before committing to the upper mountain. Above here, the gradient steepens and the path crosses extensive boulder fields as it approaches the plateau.
The summit plateau is large, featureless, and can be completely obscured by cloud. This is where navigation becomes critical. The plateau contains the ruins of an 1883 weather observatory and an emergency shelter. The cliff edge of the north face drops away very close to the summit cairn, and in poor visibility it is easy to stray towards the top of the gullies. Careful compass work and a good map are essential above the cloud line.
Key stats for the Mountain Track:
- Start point: Ben Nevis Visitor Centre, Glen Nevis (grid ref NN 122 729)
- Distance: 17km return
- Ascent: 1,344m
- Grade: strenuous
The Carn Mor Dearg Arete (CMD Arete)
The CMD Arete is a longer and more demanding route that takes in a second Munro, Carn Mor Dearg (1,220m), before crossing the dramatic curved ridge of the arete to reach Ben Nevis from the north-east. It is widely regarded as the finest walking route on the mountain.
The route begins at the Torlundy track north of Fort William or from the Allt a' Mhuilinn path above the Ben Nevis distillery, ascending Carn Mor Dearg before the narrow rocky spine of the arete. The arete itself involves some mild scrambling on large boulders and is exposed on both sides: the views down into the Allt a' Mhuilinn corrie and across to the north face of Ben Nevis are exceptional. The final pull from the arete to the summit is steep but short.
This route requires confident navigation, a head for heights on the arete, and experience of mountain terrain. It is not suitable for inexperienced walkers or in poor visibility.
Key stats for the CMD Arete:
- Distance: approximately 19km return (from Glen Nevis)
- Ascent: approximately 1,500m (including Carn Mor Dearg)
- Grade: strenuous, with some easy scrambling
- Additional requirement: confident navigation skills
Which Route Should You Choose?
For most walkers visiting Ben Nevis for the first time, the Mountain Track is the right choice. It is well-signed, well-maintained below the plateau, and the path is easy to follow in good conditions. The challenge comes from the sustained ascent and the navigation required on the upper plateau in mist.
The CMD Arete is the route to choose if you have previous mountain experience, are comfortable on rocky terrain, and want a more varied and scenically rewarding day. It adds time and distance but gives a far better appreciation of the scale and character of the mountain.
Both routes converge on the same summit and require the same level of preparation in terms of navigation, weather awareness, and equipment.
Which Maps Do You Need?
1:25,000 for Summit Navigation
For the upper mountain and summit plateau, a 1:25,000 scale OS map is strongly recommended. At this scale, 4 centimetres on the map equals 1 kilometre on the ground, and contour lines are drawn at 5-metre intervals. On Ben Nevis, this level of detail is important: the difference between the safe descent line and the top of the north face cliffs is a matter of metres, and in cloud you are navigating by compass and map alone.
The Ben Nevis summit area is covered by two 1:25,000 maps in the UK Maps range:
- Ben Nevis 25k North: covers the summit, the north face, the CMD Arete, and Carn Mor Dearg. The essential map for the upper mountain on both main routes.
- Ben Nevis 25k South: covers the lower section of the Mountain Track from Glen Nevis, including the Visitor Centre start point and Lochan Meall an t-Suidhe.
For a complete day on the mountain, both maps together give full coverage of both main routes at the detail level needed for confident navigation.
1:50,000 for General Orientation
The Ben Nevis 1:50,000 walking map covers the wider Glen Nevis area including Fort William, the surrounding glens, and the approaches to the mountain. At this scale, 2 centimetres equals 1 kilometre, giving a broader view of the surrounding area. It is useful for planning your approach and for understanding how Ben Nevis sits within the wider landscape, but the 10-metre contour interval makes it less precise for summit navigation than the 1:25,000 versions.
Many walkers carry both: the 1:50,000 for the approach and general orientation, and the 1:25,000 for the summit section.

Planning Your Ascent
Best Time of Year
Ben Nevis is walkable year-round on the Mountain Track, but the experience and required skills vary significantly by season.
Summer (May to September) is the most popular window. Days are long, the path is snow-free in most years from June onwards, and accommodation in Fort William is plentiful. The summit is still frequently in cloud, but conditions are generally more stable than in winter or spring.
Autumn (October to November) brings shorter days and less predictable weather but fewer walkers and often excellent visibility on clear days. Snow can appear from October. Early starts are important.
Winter (December to April) transforms Ben Nevis into a serious mountaineering environment. The upper mountain is covered in snow and ice, avalanche risk is real, and the summit can be exposed to extreme cold and wind. Navigation in winter conditions requires crampons, an ice axe, and the skills to use them. The Mountain Track in full winter conditions is not a walking route; it is a winter mountaineering route.
Weather
The summit of Ben Nevis receives an average of over 4,000mm of rain per year and is in cloud for more than half the year. Even on a fine day in the glen, cloud can roll in quickly above 1,000m. Always check the Mountain Weather Information Service (MWIS) forecast for the Scottish Highlands before setting out.
Navigation on the Summit Plateau
The descent from the summit in poor visibility is the most dangerous part of the route. The standard advice is to take a specific compass bearing on descent: from the summit cairn, head on a bearing of 231 degrees magnetic for approximately 150 metres before turning to follow the path down the south-western shoulder. This avoids the cliff edges immediately south and east of the summit. Study this on your map before you leave and be ready to use it.
What to Carry
- OS map at 1:25,000 scale and a compass (and the ability to use both)
- Waterproof jacket and trousers
- Warm layers (temperature drops roughly 3 degrees Celsius for every 300m of ascent)
- Food and water for a full day (7 to 9 hours)
- Headtorch in case the day runs longer than expected
- First aid kit
