Ben Macdui is the second-largest mountain in the UK, second only to Ben Nevis in Fort William, and the highest peak in the Cairngorms National Park.
The park is home to 55 Munros — a Munro being any Scottish mountain taller than 3,000 ft (914 m). The Ben Macdui hike covers 17.5 km (11 miles) and takes 6-8 hours, including a long stretch across the exposed Cairngorm plateau.
While few first-time visitors will tackle this summit on their first trip, it is an important feature of the landscape and worth understanding before you explore the range.
The Route & What to Expect
Most walkers start from the Cairngorm Mountain car park near the funicular and follow the plateau path past Coire an t-Sneachda towards the summit. The going is long rather than technical, but the plateau is featureless and navigation is hard in poor visibility.
Set aside a full day. The 6-8 hour estimate assumes reasonable fitness, dry conditions and no navigation errors on the top.
Who It Suits
This hike suits experienced hillwalkers comfortable with map, compass and Scottish mountain weather. First-timers to the Cairngorms are better served by the gentler Linn of Dee walk or the lochside loop at Loch an Eilein.
Safety & Practical Tips
- Check the mountain weather forecast (MWIS) before setting out
- Carry map, compass and the ability to use them — GPS can fail
- Pack windproof and waterproof layers even in summer
- Start early to allow 6-8 hours of daylight
- Tell someone your route and expected return time
- Turn back if visibility on the plateau drops
