Introduction
Welcome to the Aletsch Glacier Panorama Trail, a journey along the edge of the largest glacier in the Alps. The Great Aletsch Glacier stretches 22.6 kilometres from the Jungfrau massif to the Massa Gorge above Brig, covering an area of more than 80 square kilometres and containing an estimated 11 billion cubic metres of ice. If all that ice were melted, it would provide every person on Earth with roughly one and a half litres of water per day for an entire year.
In 2001, the Jungfrau-Aletsch region was inscribed as a UNESCO World Heritage Site, the first natural site in the Alps to receive this distinction. The designation recognises not only the glacier itself but the extraordinary range of habitats it has created: from raw, ice-scoured rock at its margins to ancient pine forests on its flanks, to flower-rich alpine meadows above.
Today's hike follows the southern rim of the glacier, traversing high above the ice on a well-marked trail from Bettmerhorn to the Moosfluh viewpoint above Riederalp. The route covers 12.8 kilometres with moderate elevation changes, making it accessible to any reasonably fit hiker. What it lacks in extreme physical challenge, it makes abundantly in visual drama. The glacier is your constant companion, a river of ice flowing between peaks that reach nearly 4,300 metres.
You have ascended from Bettmeralp by cable car to the Bettmerhorn station at 2,292 metres. Both Bettmeralp and Riederalp are car-free villages, accessible only by cable car from the Rhone Valley below. The absence of cars gives these villages a tranquillity that is increasingly rare in the Alps.
Before we set off: carry water and sun protection, wear good hiking boots, and pack a warm layer. Even in summer, temperatures at this altitude can drop sharply if clouds roll in. The trail is well-marked with yellow hiking signs and white-red-white blazes.
Waypoint 1: Bettmerhorn Viewpoint (2,292 m)
GPS: 46.4023N, 8.0670E
Stand at the Bettmerhorn viewpoint and look north. Below you, filling the entire valley, is the Great Aletsch Glacier. From this elevation, you can see the glacier's characteristic features: the medial moraines, dark lines of rock debris running along its length, mark where tributary glaciers have merged. The glacier's surface is scarred with crevasses, deep cracks formed by the stresses of the ice's movement over uneven bedrock.
The glacier flows at a speed of roughly 200 metres per year in its upper reaches and slows to about 50 metres per year near the terminus. This may sound slow, but over the centuries it adds up to immense distances. The ice at the terminus began its journey as snow falling near the Jungfrau some 800 to 1,000 years ago. Every snowflake that lands on the Jungfraujoch today will, if the glacier survives, emerge at the snout in roughly the year 3000.
The three dark lines, the medial moraines, visible on the glacier's surface are formed at the Konkordiaplatz, a remarkable confluence about 8 kilometres upstream where three major glacial tributaries meet: the Grosser Aletschfirn from the Jungfrau, the Jungfraufirn from the Moench, and the Ewigschneefeld from the Trugberg. The Konkordiaplatz is one of the largest glacial junctions in the Alps, a vast amphitheatre of ice that is roughly 900 metres deep at its thickest point.
The glacier is shrinking. Since measurements began in 1870, the Aletsch Glacier has retreated by over 3 kilometres and thinned by up to 350 metres. The current rate of ice loss has accelerated dramatically. What took a century to lose is now being lost in mere decades. Scientists project that even under moderate warming scenarios, the glacier will lose half its remaining volume by mid-century.
Begin walking along the trail heading west, following signs toward "Riederalp" and "Aletsch Panoramaweg."
Next waypoint: 1.0 km, approximately 20 minutes.
Waypoint 2: The Moraine Viewpoint (2,250 m)
GPS: 46.4010N, 8.0580E
The trail descends gently to a viewpoint where you can look directly down at the glacier's lateral moraine, the enormous ridge of rock debris that marks the glacier's edge. The moraine rises like a wall, grey and desolate, a stark contrast to the green meadows on which you are walking.
This moraine tells a story of retreat. The crest of the moraine marks the glacier's position at its most recent maximum, during the Little Ice Age around 1860. At that time, the ice was 200 to 300 metres thicker than it is today, and the glacier filled the valley to the top of the moraine. The distance between the moraine crest and the current ice surface is a visual measure of how much ice has been lost in just 160 years.
The lateral moraine is a hostile environment. The steep, loose slopes of gravel and rock are almost devoid of vegetation. But look carefully at the inner face of the moraine, the side that faces the glacier, and you may spot pioneer plants beginning their slow colonisation: lichens first, then mosses, then hardy grasses. This ecological succession, from bare rock to forest, takes centuries, but it has already begun on the older portions of the moraine.
On the green slopes around you, the contrast could not be greater. These meadows have had thousands of years since the last major glaciation to develop deep, rich soil, and they support a lush community of wildflowers. In early summer, the golden cinquefoil, the purple alpine clover, and the delicate white stars of Grass of Parnassus create a tapestry of colour.
Next waypoint: 1.5 km, approximately 25 minutes.
Waypoint 3: The Aletsch Forest Approach (2,180 m)
GPS: 46.3998N, 8.0450E
As the trail continues westward, you approach one of the most remarkable forests in the Alps: the Aletschwald, or Aletsch Forest. This ancient Swiss stone pine forest, protected since 1933, clings to the steep slopes above the glacier and is one of the largest and oldest stone pine forests in the country.
The trees here are old. Some of the stone pines, Pinus cembra, are over 900 years old, and the oldest documented tree in the forest is estimated at over 1,000 years. These ancient trees have survived countless storms, avalanches, and climatic fluctuations. Their twisted, gnarled trunks and wind-sculptured crowns bear witness to centuries of alpine weather.
The Aletsch Forest is also ecologically precious because it has been largely undisturbed by human activity for centuries. The steep, rocky terrain made logging impractical, and the forest was legally protected long before conservation was fashionable. The result is a near-natural ecosystem, with standing deadwood, fallen logs, and a complex understorey that supports a rich community of fungi, insects, and birds.
Listen for the cracking call of the spotted nutcracker, Nucifraga caryocatactes. This corvid has a symbiotic relationship with the stone pine: it feeds on the pine's nutritious seeds, caching thousands of them in the soil each autumn. The seeds it forgets germinate into new trees. Without the nutcracker, the stone pine would struggle to disperse its heavy seeds, and without the pine, the nutcracker would lose its primary food source. It is one of the classic mutualisms of Alpine ecology.
Next waypoint: 1.2 km, approximately 20 minutes.
Waypoint 4: The Heart of the Aletsch Forest (2,100 m)
GPS: 46.3988N, 8.0355E
The trail now passes through the Aletsch Forest itself. Walk slowly here and absorb the atmosphere. The ancient stone pines tower above you, their blue-green needles soft against the sky. The forest floor is carpeted with bilberry, heather, and thick cushions of moss. The air is fragrant with the distinctive resinous scent of stone pine, a scent that studies have shown reduces stress hormones and lowers heart rate.
The largest trees have trunk diameters exceeding a metre and heights of over 25 metres. But size can be misleading. A stone pine growing at 2,000 metres may take 50 years to reach the height of a sapling that a lowland tree would achieve in 5 years. Growth at this altitude is painfully slow, limited by the short growing season, cold temperatures, thin soil, and intense winter conditions.
The trees are festooned with lichens, particularly the pale green Usnea, or old man's beard, which hangs from the branches in long, wispy strands. Lichens are not parasites; they are composite organisms, a partnership between a fungus and an alga. The abundance of lichens in the Aletsch Forest is an indicator of clean air, as lichens are highly sensitive to air pollution.
Keep your eyes open for red deer, which inhabit the forest, and for the black woodpecker, Europe's largest woodpecker, whose loud drumming echoes through the pines in spring.
Next waypoint: 1.0 km, approximately 20 minutes.
Waypoint 5: The Villa Cassel Junction (2,050 m)
GPS: 46.3975N, 8.0280E
Near the trail, you will see signs pointing toward the Villa Cassel, a grand Victorian mansion perched on the hillside above Riederalp. This impressive building, constructed in 1900 as a summer residence for the English financier Sir Ernest Cassel, now serves as the Pro Natura Centre Aletsch, a nature education centre run by Switzerland's oldest conservation organisation.
Sir Ernest Cassel was one of the wealthiest men in Europe, a friend and financial advisor to King Edward VII. He chose this remote mountain location for his summer retreat, building a villa that would not have looked out of place in a London square. The guest book of the Villa Cassel reads like a who's who of Edwardian high society: Winston Churchill visited and reportedly painted watercolours of the glacier from the terrace.
The Pro Natura Centre offers excellent exhibitions on the glacier, the Aletsch Forest, and alpine ecology. If you have time, it is well worth a visit. The centre also organises guided walks into the protected Aletsch Forest, providing access to areas that are otherwise closed to the public to protect the fragile ecosystem.
From this junction, you can choose to descend to the centre or continue along the main panorama trail toward the Moosfluh viewpoint. We continue on the panorama trail.
Next waypoint: 1.5 km, approximately 25 minutes.
Waypoint 6: Riederalp Panorama Section (2,080 m)
GPS: 46.3960N, 8.0250E
The trail traverses open alpine meadow above Riederalp, with continuous views of the glacier to the north. This stretch is particularly beautiful in late afternoon, when the setting sun illuminates the ice and the surrounding peaks in warm, golden light.
Look at the glacier and try to appreciate its three-dimensional form. The ice is not flat; it has a complex surface topography of ridges, troughs, and crevasse fields. The largest crevasses can be 30 to 40 metres deep and are concealed by thin snow bridges in the accumulation zone. These hidden crevasses are among the greatest dangers for anyone travelling on the glacier, and venturing onto the ice without a guide and proper equipment is extremely dangerous.
The peaks on the far side of the glacier include some of the highest in the Bernese Alps. The Aletschhorn, at 4,193 metres, is the most prominent, a beautiful pyramid of rock and ice that stands slightly apart from the main Jungfrau chain. It was first climbed in 1859 by Francis Fox Tuckett with guides Johann Bennen and Peter Bohren, during the golden age of Alpine mountaineering.
To the east, the Fiescher Gaebelihorn and Gross Wannenhorn form a formidable wall of 4,000-metre peaks. The glacier that bears their meltwater, the Fieschergletscher, is visible as a separate ice tongue running parallel to the Great Aletsch Glacier.
Next waypoint: 1.5 km, approximately 25 minutes.
Waypoint 7: The Riederfurka Area (2,065 m)
GPS: 46.3948N, 8.0195E
You are approaching the Riederfurka, a broad saddle between Riederalp and the slopes above the glacier. This area is a crossroads of trails, and you will see signs pointing in multiple directions.
The meadows in this area are botanically rich. In June and July, the early purple orchid, Orchis mascula, and the small white orchid, Pseudorchis albida, can be found in the damp grassland. Alpine asters, harebells, and dozens of other species create a floral display that attracts clouds of butterflies, including the striking Apollo butterfly, Parnassius apollo, with its white wings marked by red eye-spots.
The Apollo butterfly is a species of conservation concern in many parts of Europe, having disappeared from lower-altitude sites due to habitat loss and climate change. Here at altitude, the population remains healthy, sustained by the abundant food plants and the traditional management of the alpine meadows. The caterpillars feed on stonecrop, Sedum album, which grows on rocky ground.
The cultural landscape here is shaped by the Walliser, the German-speaking people of the upper Rhone Valley. The Valais dialect, Walliserdeutsch, is one of the most conservative Germanic dialects, preserving features from medieval German that have disappeared elsewhere. It is so different from standard German that even other Swiss-German speakers often find it incomprehensible.
Next waypoint: 1.0 km, approximately 15 minutes.
Waypoint 8: The Glacier Terminus View (2,030 m)
GPS: 46.3940N, 8.0155E
From this viewpoint, you can look down the length of the glacier toward its terminus, where the ice melts into the turbid waters of the Massa river. The terminus is roughly 6 kilometres away, but on clear days it is visible as a dirty, broken edge of ice where the glacier literally comes apart.
The glacier's terminus has been retreating steadily. A century ago, the ice extended nearly to the Massa Gorge. Today, a proglacial lake is forming at the snout as ice melts faster than it can be replenished by snowfall in the accumulation zone above. This lake, like similar lakes forming at the feet of retreating glaciers worldwide, grows larger each year.
The retreat of the Aletsch Glacier has exposed landscapes that have been covered by ice for millennia. In some areas, tree stumps and organic material have emerged from beneath the ice, radiocarbon-dated to the Medieval Warm Period around 1,000 years ago or even earlier. This tells us that the glacier was smaller than it is today during certain periods in the past, and that our current climate trajectory is pushing it toward dimensions it has not experienced in thousands of years.
Next waypoint: 1.5 km, approximately 25 minutes.
Waypoint 9: Moosfluh Viewpoint (2,065 m)
GPS: 46.3930N, 8.0225E
You have reached the Moosfluh viewpoint, and the scene before you is one of geological drama made visible in real time.
Below the viewpoint, the slopes descend steeply to the glacier. But something is wrong: the hillside is moving. The Moosfluh rockslide is one of the most studied mass movements in the Alps. As the glacier has thinned and retreated, it has removed the buttress that supported these steep slopes. Without the ice pressing against the rock, the mountain has begun to slide.
The movement is slow by human standards, a few centimetres to a few metres per year, but it is visible in the tilted trees, cracked earth, and distorted trails. Scientists monitor the slide with GPS stations, satellite radar, and other instruments. The total volume of rock in motion is estimated at hundreds of millions of cubic metres, making it one of the largest active landslides in the Alps.
This is a vivid illustration of how glaciers shape the landscape not only by their presence but by their absence. When glaciers occupy a valley, they support the valley walls. When they retreat, the walls lose their support and can collapse. Similar processes are happening at retreating glaciers worldwide, and the hazards they pose to infrastructure and communities are a growing concern.
Closing
You have completed the Aletsch Glacier Panorama Trail. Over roughly four hours and 12.8 kilometres, you have walked alongside the greatest glacier in the Alps, passed through an ancient forest of millennial stone pines, and witnessed the dynamic processes of glacial retreat and landscape change.
From the Moosfluh, the Riederalp cable car descends to Morel in the Rhone Valley. Alternatively, you can walk to the car-free village of Riederalp in about 20 minutes and take the cable car from there.
The Great Aletsch Glacier is a monument to the forces that shaped the Alps and a barometer of the changes now sweeping across our planet. Whatever its future, the memory of standing above this vast river of ice, hearing it creak and groan as it flows imperceptibly toward the valley below, is one that stays with you.
Thank you for hiking with ch.tours. Safe travels, and cherish the ice while it remains.
