Para-Monte ambassador Fergus Cowley recently completed the iconic Tour du Mont Blanc (TMB), trekking through France, Italy and Switzerland while representing the charity in one of Europe’s premier mountain environments.

Over seven unforgettable days, Fergus circumnavigated Mont Blanc (4,805 m), the highest mountain in the Alps. Along the way he experienced spectacular scenery, challenging mountain terrain and firsthand insights into altitude awareness. Here he shares his reflections, practical advice and lessons learned from the journey.

The Trek at a Glance:

The Tour du Mont Blanc is widely regarded as one of the world’s greatest long-distance hikes, attracting thousands of walkers from across the globe each year.

The route circles Mont Blanc, passing through France, Italy and Switzerland before returning to Chamonix. Although the highest point of the trek, Grand Col Ferret (2,537 m), is well below the elevations associated with serious altitude illness, it is high enough for many people to notice the effects of altitude for the first time, making it an excellent introduction to mountain environments.

The trek typically takes between 7 and 10 days to complete. Walkers can choose between a fully guided package (typically £2,000+), hiking independently while staying in mountain huts (£900–£1,500), or camping (£400–£600). We chose to hike independently and camp throughout the route.

Our journey:

Days 1–3: France to Italy:

Our adventure began with the optional cable car from Les Houches, quickly gaining elevation and providing spectacular views of Mont Blanc’s glaciers and surrounding peaks. The opening day wound through beautiful alpine meadows and then descended to Les Contamines-Montjoie, where campsites, restaurants and shops provided an ideal first overnight stop.

The following two days became noticeably more remote, villages disappeared, replaced by rugged mountain scenery and welcoming refuges that served hot meals and drinks. Several designated camping areas can be found along this section.

On the third day we crossed Col de la Seigne (2,516 m) and entered Italy. Although this elevation is not high enough to cause altitude sickness in healthy individuals, many walkers will notice subtle effects of altitude exposure, such as an increased heart rate,

heavier breathing and a slower walking pace. After descending into Italy, a shuttle bus provided easy access to the mountain town of Courmayeur.

This section involves approximately 15–20 km of walking each day with around 1,000 m of ascent and descent. The trails are exceptionally well maintained with no technical climbing required, making the route achievable for fit novice hikers with appropriate preparation.

Days 4–5: Italy to Switzerland

Italy provided two fantastic days of hiking, excellent food and some of the finest views of Mont Blanc anywhere on the circuit. The first day follows high balcony trails overlooking the valley, while the second climbs steadily to Grand Col Ferret (2,537 m), crossing into Switzerland and offering breathtaking panoramic views across both countries.

The first day is relatively gentle, covering around 10 km with approximately 500 m of ascent. The second day is considerably more demanding, involving roughly 20 km and 1,000 m of climbing. Despite the physical challenge, the trails remain straightforward and well-marked throughout.

‍

Days 6–7: Switzerland back to France

Poor weather on our sixth day meant choosing one of the lower route alternatives, taking us through peaceful forest trails before crossing back into France. For our final day we added a memorable detour to the Albert 1er Refuge, dramatically perched beside the Tour Glacier. This proved to be the biggest climbing day of the trip and included crossing patches of lingering snow from the previous winter. Although we carried micro spikes as a precaution, they were not required during our visit.

Seven days after setting out, we returned to Chamonix tired but immensely proud to have completed one of the world’s classic mountain treks.

What we Learned:

• The Tour du Mont Blanc is an excellent introduction to altitude. Most people will notice the physiological effects of thinner air without being at significant risk of altitude sickness.
• Visitors should still be aware of the altitude risks elsewhere in the Mont Blanc region. Cable cars can transport tourists to almost 3,800 m within minutes, and accommodation is available above 3,400 m. Rapid ascents like these can increase the risk of acute mountain sickness (AMS) if sufficient acclimatisation is ignored.
• Many people underestimate the demands of climbing Mont Blanc itself. At 4,805 m, successful and safe ascents require careful acclimatisation, appropriate equipment and good decision-making.
• We encountered many first-time mountain visitors throughout the region, highlighting the importance of altitude education and preparation.
• The professionalism of the local mountain guides and rescue services was outstanding, providing an invaluable safety network for visitors.

Top Tips:

• If camping, arrive early to secure a good pitch, particularly during the busy summer months.
• Resist the temptation to plan overly ambitious days. The combination of steep climbs, long distances and altitude is more tiring than many people expect.
• June and September generally offer a quieter experience than the peak summer season, when campsites, mountain huts and buses become extremely busy.
• If travelling in June, check current trail conditions before setting off, as snow can remain on higher passes. Micro spikes may still be useful.
• Don’t underestimate the cumulative fatigue of hiking for seven consecutive days. Ensure both your footwear and your body are well prepared before the trip.

How to Prepare:

• Thoroughly break in your hiking boots before travelling to minimize the risk of blisters.
• Aim to comfortably walk 20 km while climbing around 1,200 m in a day.
• If you don’t have access to hills, cycling in a high gear or using a stair machine can help build climbing fitness.
• Regular calf raises can help prepare your calves and Achilles tendons for repeated uphill walking.
• Train by walking on consecutive days to prepare your body for limited recovery between stages.

Essential kit

• Blister plasters and sports tape.
• Micro spikes (early season if snow remains).
• High-factor sunscreen and lip balm, the intensity of UV radiation increases with altitude.
• Dry bags to keep clothing and sleeping equipment dry during heavy rain.
• Trekking poles to reduce fatigue on long descents.
• Warm clothing for evenings, as temperatures drop quickly after sunset.
• A reliable waterproof jacket, as afternoon thunderstorms are common in the Alps.

The Tour du Mont Blanc is far more than a scenic walking holiday. It is an unforgettable mountain journey that introduces thousands of people each year to hiking at altitude.

With sensible preparation, respect for the mountain environment and an understanding of how altitude affects the body, it is a challenge that is both achievable and immensely rewarding.

Para-Monte exists to improve awareness of altitude illness and help people enjoy the mountains safely. Hopefully, sharing experiences like these encourages more people to prepare well, recognise the effects of altitude, and make informed descisions in the mountains.

On behalf of all of us at Para-Monte, we like to thank Fergus for completing the Tour de Blanc as well as raising that all important Altitude Awareness!!
