Ben Macdui: the Walk to Britain's Second Highest Peak

Rising to an impressive 1309 metres, Ben Macdui is the UK’s second highest mountain, standing proudly within the rugged expanse of the Cairngorms National Park. Second only to Ben Nevis, this iconic peak is a magnet for experienced hillwalkers, offering a demanding yet rewarding adventure. With its vast summit plateau, sweeping views, and fascinating folklore, the Ben Macdui walk is an unforgettable journey into the heart of the Scottish Highlands.

However, this is no ordinary hike. The terrain is strenuous, the navigation can be tricky, and the weather is notoriously unpredictable. Whether you choose the popular Northern Corries approach from the Cairn Gorm ski car park or the more challenging Lairig Ghru route, a walk to Ben Macdui demands preparation and respect for the mountain’s formidable conditions. In this guide, we’ll take you through everything you need to know to tackle this mighty peak safely and with confidence.

Route Overview

Height: 1309m (UK’s second highest mountain) Main Route: Northern Corries from Cairn Gorm ski car park Distance: Approximately 18-20km return Ascent: 800-900m Time: 7-9 hours for fit walkers Difficulty: Strenuous Alternative Route: Lairig Ghru from Aviemore (25-32km, 10-12+ hours)

Getting to the Start

The most accessible and popular starting point for the Ben Macdui hike is the Cairn Gorm ski car park, located at grid reference NN 978 968 (postcode PH22 1RB). It sits at an elevation of roughly 600m, providing a helpful head start. Parking charges apply (approximately £5-10 per day), and it’s worth noting that the car park is open year-round, though conditions in winter may vary depending on ski operations. Facilities include picnic benches and a café, making it a convenient staging point. While public transport options to the car park are limited, you can reach nearby Aviemore by train or bus and arrange a taxi for the remaining distance.

For those attempting the Lairig Ghru route, the Linn of Dee car park (grid ref NO 063 898) near Braemar is the usual starting point. It’s 10km west of Braemar village and also requires a parking fee. This route demands a longer walk-in and is better suited for seasoned hikers or those planning a multi-day excursion.

The Walk Step by Step

The Northern Corries route is the most commonly used approach to Ben Macdui. Offering dramatic scenery, it’s a favourite among those seeking a challenging yet straightforward ascent. Below, we outline the route in detail:

Stage 1: Northern Corries Ascent

Start from the Cairn Gorm ski car park and follow the well-maintained paths leading towards the Northern Corries. This section provides stunning views into Coire an t-Sneachda, with its steep crags and rugged beauty. The path is straightforward but steep in places, so pace yourself as you climb. Look out for hardy wildlife such as ptarmigan and mountain hares, which blend seamlessly into the tundra-like terrain.

Stage 2: Crossing the Plateau

As you gain height, the landscape opens up onto the Cairngorm plateau, a vast and featureless expanse that can feel otherworldly. Navigation skills are critical here, especially in poor visibility. Stick to the paths where possible to protect the fragile environment and avoid disorientation. The southwest edge of the plateau offers views down into the Loch Avon basin - a spectacular sight on clear days.

Stage 3: Final Ascent to the Summit

From the plateau, the path turns towards Ben Macdui’s summit. The terrain becomes rockier, with boulder fields to negotiate. Take care with your footing, particularly in wet or icy conditions. As you approach the summit, you’ll spot the large cairn and trig point that mark the top. On a clear day, you’ll be rewarded with breathtaking views, including glimpses of Ben Nevis to the west and Braeriach to the south.

Stage 4: Return Journey

Retrace your steps carefully across the plateau and back down through the Northern Corries to the car park. Descending can be just as tricky as climbing, particularly if fatigue sets in, so take your time. Ensure you leave no trace and stick to established paths to minimise your impact.

What You Will Need

• Navigation: OS Explorer 403/OL57 maps, compass and GPS device. The summit plateau is infamous for its challenging navigation.
• Clothing and Kit: Sturdy walking boots, waterproofs, warm layers, gloves and a hat. In winter, crampons and an ice axe are essential.
• Supplies: Plenty of water, high-energy snacks, and a packed lunch. A thermos of hot drink is a morale booster in cold weather.
• Emergency Gear: A bothy bag, headtorch, first aid kit, and fully charged mobile phone.
• Fitness: A good level of fitness is essential for this strenuous walk.

Safety and Hazards

The Cairngorm plateau is one of the most hazardous areas for walkers in the UK. Weather conditions can change rapidly, and whiteouts are common in winter. Strong winds, heavy snow, and freezing temperatures make survival difficult for the unprepared. Always check the weather forecast before setting off, and carry appropriate winter gear between November and April.

Navigation errors are a primary cause of mountain rescue callouts in this area. Ensure you have the skills and equipment to navigate safely, especially in poor visibility. If conditions are unfavourable, don’t hesitate to turn back - Ben Macdui will always be there for another day.
