Stellisee

Stellisee is a small alpine lake above Zermatt in the Swiss canton of Valais, sitting at roughly 2,530 m on the path between the Blauherd lift station and the Fluhalp mountain restaurant. People come for one image: on a windless day the whole Matterhorn is mirrored in the water, which is why locals also call it the mirror lake.

How do you get to Stellisee?

From Zermatt, take the underground Sunnegga Express to Sunnegga, then change to the gondola up to Blauherd. From the top station a well-kept path leads to the lake in about 20 minutes. The ground is gentle, with no steep climbs, so you do not need mountaineering experience. Sturdy shoes and a windproof layer are enough, since the temperature drops quickly at this altitude.

What will you see at the lake?

The lake is compact, ringed by rocky shores and low slopes. The draw is the view: the Matterhorn rises straight above the water, and in clear air you can also pick out the glaciers and peaks of the Mattertal valley. A small chapel stands near the shore, and a themed trail linking several lakes passes close by. Stellisee works as the midpoint stop on the Blauherd to Fluhalp walk.

What is the Blauherd to Fluhalp route like?

The stretch between Blauherd and Fluhalp stays almost level at around 2,500 m and takes 45 to 60 minutes one way, with the lake roughly halfway. Beyond it the path climbs gently to the Fluhalp restaurant at about 2,610 m, where you can sit on a terrace facing the Matterhorn. In winter the same route is prepared as a walking trail, so it is reachable outside the summer season too.

Is Stellisee part of the Five Lakes Trail?

Yes. The popular Five Lakes loop starts at Blauherd and links Stellisee, Grindjisee, Grünsee, Moosjisee and Leisee. The Matterhorn reflects in three of the five. The full circuit usually takes 3 to 5 hours depending on pace and stops. With limited time, visit Stellisee alone and return to Blauherd the way you came. Each lake has its own character, and Stellisee is the one photographed most often.

When should you visit for the reflection?

A mirror image needs still air, and mountain wind is usually calmest early in the day. That is why photographers aim for sunrise, when the Matterhorn glows pink and the surface stays smooth. Zermatt Bergbahnen runs dedicated early-morning lift rides for this purpose. In summer the trail is typically snow-free from June to October. Afternoons bring more walkers and less flattering light for pictures.

What should you pack?

• Sunglasses and sunscreen, since UV is strong at 2,500 m.
• A thin windproof jacket, even on a sunny day.
• Water, and snacks for longer routes; food is only available at Blauherd and Fluhalp.
• A camera and tripod if you plan dawn shots.
