The Arosa Line is a scenic metre-gauge railway linking Chur with the mountain resort of Arosa in Graubünden. Operated by the Rhaetian Railway (RhB), the route leaves the streets of Switzerland’s oldest city and climbs through the Schanfigg Valley to an alpine setting of forests, villages, deep ravines, and high mountain slopes.
The railway opened in 1914 and remains both a practical transport link and a memorable sightseeing journey. According to RhB, the Arosa Line gains roughly 1,000 metres in about one hour, making the rapid change from city streets to mountain scenery one of the most distinctive parts of the trip.
Quick Answer
For the most dramatic scenery on the Arosa Line, focus on the upper Schanfigg section around Peist and Langwies through the approach to Arosa. The Langwieser Viaduct is the standout engineering landmark, while the surrounding valley offers steep forested slopes, alpine villages, ravines, and increasingly high mountain views.
Key Takeaways
- The Arosa Line runs from Chur to Arosa in about one hour, with service normally operating hourly according to Arosa Tourism.
- The upper Schanfigg section around Langwies is the strongest choice if your priority is alpine scenery and railway engineering.
- The Langwieser Viaduct is one of the route’s signature sights, standing 62 metres high and measuring roughly 285 metres in length.
- The Arosa Line is an adhesion railway, not a rack-and-pinion railway.
- There is no single best side of the train for the entire trip because the route curves frequently and views change sides.
- Check the current RhB timetable before travel because schedules, engineering work, and connections can change.
Arosa Line: A Scenic Railway Journey from Chur to Arosa
The journey begins at Chur, which Chur Tourism describes as Switzerland’s oldest city. The historic centre is worth exploring before or after the train ride, especially if you have enough time to combine the railway journey with a walk through the old town.
What makes the beginning of the Arosa Line unusual is how closely railway and city life meet. After leaving Chur station, the train runs through the urban area before following the Plessur and climbing toward Schanfigg. City buildings gradually give way to wooded slopes, villages, ravines, and increasingly open mountain views.
The line is a metre-gauge mountain railway and was opened in 1914, according to the Rhaetian Railway’s official history. Despite its steep ascent, it does not use a rack-and-pinion system. The train relies on conventional adhesion between its wheels and rails.
RhB describes the Arosa Line as climbing about 1,000 metres from Chur into the mountains in roughly one hour.
This combination of a relatively short journey, substantial elevation gain, historic engineering, and changing scenery is why the ride feels very different from an ordinary regional train trip.
Arosa Line: Best Section for Breathtaking Views
The whole Chur-to-Arosa journey has interesting scenery, but if you want to identify one particularly rewarding portion, the upper Schanfigg section around Peist, Langwies, and the final approach toward Arosa is the strongest choice.
Earlier in the journey, the attraction is the transition from Chur’s streets into the valley. As the train gains height, however, the surroundings become more alpine. Forested slopes rise sharply around the railway, villages appear across the valley, and the line crosses increasingly dramatic terrain.
The most famous engineering landmark is the Langwieser Viaduct. RhB describes the reinforced-concrete structure as 62 metres high and roughly 285 metres long. It has crossed the gorge near Langwies since the Arosa railway opened in 1914.
The viaduct is more important to the route than any supposed feature called an “Arosa Loop.” There is no need to look for a named railway loop. Instead, watch for the changing views around Langwies, the deep valley below, the concrete viaduct, and the increasingly high alpine landscape as the train continues toward Arosa.
Pro Tip: Do not worry too much about choosing a “correct” side of the train. The railway bends repeatedly, so good views move from one side to the other. A clean window, daylight, and a seat where you can look comfortably in both directions usually matter more.
Route Facts and What You See Along the Arosa Line
| Route | Chur to Arosa |
| Operator | Rhaetian Railway (RhB) |
| Typical journey time | About 1 hour |
| Typical frequency | Hourly according to current Arosa Tourism information; always check the timetable for your date |
| Railway type | Metre-gauge adhesion railway; no rack-and-pinion system |
| Major scenic landmark | Langwieser Viaduct |
| Arrival in Arosa | Arosa station beside Obersee |
The scenery changes noticeably over the journey. Near Chur, passengers see the urban railway environment and the lower Plessur Valley. Farther up Schanfigg, wooded slopes, mountain settlements, bridges, and steep ravines become more prominent.
Near Langwies, the railway’s engineering becomes a major part of the view. The final section toward Arosa feels increasingly alpine, and arrival beside Obersee makes a strong finish to the journey.
Note: The Arosa Line should not be confused with RhB’s Albula and Bernina railway lines that form the Rhaetian Railway UNESCO World Heritage property. The Arosa Line is scenic and historic, but it is not part of that UNESCO railway core zone.
Exploring the Arosa Line: Highlights and Points of Interest
| Point of Interest | Why It Matters |
| Chur | Starting point, historic old town, and unusual transition from urban streets to a mountain railway |
| Schanfigg Valley | Forest, steep valley sides, villages, bridges, ravines, and increasingly alpine scenery |
| Langwies and Langwieser Viaduct | One of the most impressive engineering and photography highlights on the line |
| Arosa Train Station | Upper terminus and arrival point beside Obersee |
| Obersee | Convenient lakeside scenery immediately after arriving in Arosa |
| Arosa Weisshorn area | A mountain excursion available after reaching Arosa rather than a sight directly beside the entire railway route |
Langwies is worth particular attention. The village sits in the upper Schanfigg area and gives access to hiking country as well as the railway’s best-known viaduct. Travelers who have more time can turn the train journey into a longer excursion by stopping in the valley rather than riding directly to Arosa and back.
Arosa itself offers a very different atmosphere from Chur. The station is next to Obersee, making the lake one of the easiest sights to enjoy immediately after getting off the train. From Arosa, visitors can continue toward hiking areas, mountain transport, winter-sports facilities, shops, restaurants, and other local attractions.
Tips for Making the Most of Your Arosa Line Experience
Check the timetable for your exact travel date
Arosa Tourism currently states that RhB trains run hourly between Chur and Arosa and that the journey takes about one hour. However, timetable changes and engineering work can affect individual services, so verify your connection before departure.
Buy the correct ticket rather than looking for a panoramic-train reservation
The Arosa Line is served by regular RhB trains. You need a valid ticket for your journey, which can be purchased through official railway sales channels. RhB’s current individual seat-reservation option for regional trains applies specifically to the Bernina Line, so travelers should not assume that the Arosa Line works like the reservation-based Bernina Express.
For current fares and connections, use the official RhB ticket and timetable information.
Travel in daylight
If scenery is your priority, choose a trip with full daylight. Early morning and late afternoon can give softer light for photographs, while the middle of the day may make it easier to see details deep in the valley when the sun is high.
Do not depend on one side of the train
The railway changes direction repeatedly as it follows the terrain. Instead of treating the right or left side as permanently superior, watch both sides as the train climbs. If the carriage is quiet enough to move without disturbing other passengers, different windows may work better at different points.
Reduce reflections when taking photos
Photographing through railway windows can create glare. Hold your phone or camera close to the glass without touching it, avoid using flash, and use darker clothing or your hand to block reflections when practical.
Allow time in both Chur and Arosa
The journey is more rewarding when it is not treated only as transportation. Chur’s old town works well before departure, while Obersee and central Arosa are easy to explore after arrival.
Warning: Mountain weather can change quickly, especially if you plan to combine the train with hiking, skiing, snowshoeing, or other outdoor activities. Check current local weather, trail, lift, and transport conditions before setting out.
Best Time of Year for Arosa Line Views
The railway operates as transportation rather than as a seasonal sightseeing attraction, so the scenery changes considerably through the year.
Summer
Summer brings green slopes, forests, hiking access, and long daylight hours. It is a good choice if you want to combine the train with walking, mountain biking, or time beside the lakes in Arosa.
Autumn
Autumn can bring attractive color to the forests and clearer-looking mountain air on suitable weather days. Daylight becomes shorter, so check sunset time when planning a late trip.
Winter
Snow can completely change the appearance of Schanfigg and Arosa. Winter is especially attractive if you are combining the railway with skiing, sledding, snowshoeing, or a winter stay in the resort.
Spring
Spring is a transition season. Conditions may look wintry at higher elevations even when lower areas around Chur feel mild. That contrast can make the climb particularly interesting, but outdoor trail conditions can vary greatly.
Arosa Line: Activities and Attractions Along the Route
The Arosa Line is useful not only as a sightseeing ride but also as a gateway to outdoor activities in Schanfigg and Arosa. Hiking routes range from short walks to more demanding mountain outings, allowing travelers to combine railway travel with time on foot.
In summer, Arosa and the surrounding mountains attract hikers and mountain bikers. Travelers who stop in communities along Schanfigg can also explore quieter trails away from the main resort centre.
Winter changes the focus to snow sports. Arosa is part of a major ski region, while winter walking, snowshoeing, and sledding provide alternatives for visitors who do not ski.
For a relaxed outing, simply walking around Obersee or spending time in central Arosa can be enough. The lake’s location beside the railway station makes it practical even on a short visit.
Arosa Line: Dining and Accommodation Options
Chur has a broad selection of restaurants, cafés, and accommodation, making it a convenient place to eat before boarding the train or to stay overnight before continuing into the mountains. Traditional Swiss dishes such as fondue and raclette are widely associated with alpine travel, although menus naturally vary by restaurant and season.
Arosa offers everything from casual places to eat to upscale hotels and spa properties. Visitors staying overnight can also use the resort as a base for hiking in summer or snow sports in winter.
Because restaurant opening days, hotel availability, and seasonal operations change, check individual businesses directly before building a tightly timed itinerary around them.
The Arosa Line – A Must-See Railway Journey
The Arosa Line stands out because it combines several different experiences in a journey of only about an hour. It begins in the urban setting of historic Chur, follows the Plessur into Schanfigg, crosses major railway structures such as the Langwieser Viaduct, and ends beside Obersee in the mountain resort of Arosa.
Its appeal does not depend on a panoramic train or a rack railway. The ordinary RhB journey is the attraction: steep gradients, changing valley scenery, historic engineering, alpine villages, and a rapid transition from city to mountains.
If views are your main reason for riding, give the most attention to the upper Schanfigg section around Langwies and the final approach to Arosa. If you have more time, combine the railway with Chur’s old town, a stop in Schanfigg, a walk around Obersee, or an outdoor activity in Arosa.
