While we are used to signs in road traffic, the signage on ski slopes can be confusing at first.
Especially when you are in a larger ski area for the first time, you will quickly be overwhelmed by the multitude of signs and colors.
What do the colors green, blue, red, yellow or black mean on ski slopes?
What criteria determine whether a slope is classified as blue, red or black?
In this article, you will learn everything you need to know about the slope markings in the ski resorts of the Alps and worldwide.
We also present suitable ski resorts for each piste category.
The most important facts summarized in advance
- Slope colors indicate the level of difficulty: Blue stands for easy, red for medium and black for difficult – these markings are based on the steepness of the slopes.
- Green slopes are ideal for beginners: with a gentle gradient of 6 to 25 percent, they are ideal for novice skiers, especially in France and North America.
- Blue slopes for beginners and families: These slopes have a gradient of up to 25 percent and offer beginners a safe way to learn skiing techniques.
- Red slopes for advanced skiers: With a gradient of less than 40 percent, they are suitable for more experienced skiers who want to refine their technique.
- Black slopes for professionals only: With a gradient of more than 40 percent, they are a challenge and should only be tackled by very experienced skiers.
- Ski routes for adventurers: Marked and secured, but not groomed – ideal for experienced skiers who want to ski on uneven terrain.
- Open terrain harbors risks: as soon as the markings stop, unsecured terrain begins with an increased risk of avalanches and falls.
A color orientation for ski slopes
When you enter a large ski area for the first time, you will be greeted by a multitude of signs.
The question of whether a slope is blue, red or black quickly arises.
But what do these colors mean when skiing?
How are the slopes classified?
To avoid any possible confusion, we would like to explain the different slope markings in the Alps and other regions in more detail.
We also present some of the best ski resorts for every level of difficulty.
What the colors on the ski slopes indicate
The color coding of the slopes provides information about the difficulty level of the respective descent.
It shows whether a run is suitable for beginners or whether it is better suited to advanced skiers due to its steepness.
The numbering of the slopes makes it easier to find your way around large ski areas and prevents anyone from straying from the path.
You can also get this and much more information from our Kaprun ski school.
In some cases, the numbers are supplemented by slope designations to make orientation easier.
In addition, the edges of the slopes are marked with poles that are either painted in bright colors to increase visibility or in the respective slope color.
Green ski slopes – easy runs for beginners
In the German-speaking regions, a green sign indicates very flat, easy slopes, which are often used as practice slopes.
This is where beginners learn to ski.
In France and North America, green slopes are more common.
These slopes have a gradient of 6 to 25 percent and are ideal for practising the correct fall or mastering the first turns.
Ski resorts such as Les Deux Alpes and Alpe d’Huez in France offer a variety of green slopes.

Other countries, other colors
The colors blue, red and black are the most common and stand for easy, medium and difficult respectively.
This classification is based on the maximum gradient of the slope.
In some countries, such as Norway, France, the USA and Canada, there are also green slopes.
In Canada and the USA, there is also an additional classification for particularly difficult, deep black slopes.
The following explains when a slope is green, blue, red or black.
Blue slopes – ideal for beginners and families
A blue piste marker indicates a flat ski slope, which is often jokingly referred to as a ski highway.
With a gradient of up to 25 percent, these slopes are ideal for beginners, returners and families with children.
Various skiing techniques such as snowploughing, turning and carving can be practised on blue slopes.
Here, skiers can expect a leisurely descent without a big adrenaline rush.
In North America, on the other hand, a blue square means a steeper gradient of 25 to 40 percent.
Recommended ski resorts with many blue slopes are Winterberg in Germany, the Tiroler Zugspitz Arena in Austria and Alta Badia in Italy.
Red slopes – for advanced skiers
Red slopes in the Alps are of medium difficulty and have a gradient of less than 40 percent.
They are less suitable for beginners and are used by advanced skiers to improve their technique or prepare for steeper descents.
Experienced skiers can refine their carving technique on red slopes, while short turns are recommended for everyone else.
Ski resorts such as Saalbach in Austria, Oberstdorf in Germany and Val Gardena in Italy offer a variety of red slopes.

Black slopes – only for experienced skiers
Black runs are extremely steep and are reserved for experienced skiers.
A gradient of more than 40 percent poses a considerable risk for beginners.
You should only ski on these slopes if you have a good command of short turns.
When carving on black slopes, centrifugal force can quickly become a problem.
In America, the symbol of a black diamond indicates a difficult slope with a gradient of over 40 percent.
Two black diamonds indicate an extremely difficult descent with special challenges such as tight bends and unclear edges.
Ski resorts in Europe with many black slopes are Davos-Klosters and the Andermatt-Sedrun ski arena in Switzerland as well as Ski Arlberg in Austria.
Ski routes – For the adventurous
Ski routes marked in yellow or red dashed lines on the piste map are becoming increasingly common in the Alps.
These slopes are marked and secured, but not groomed.
Such runs are suitable for very experienced skiers and snowboarders, as the route is often uneven and you can also encounter deep snow.
Marked ski routes can be skied without a guide, as the alpine dangers are no greater than on other slopes.
Well-known ski resorts with many ski routes are Davos-Klosters in Switzerland, Fieberbrunn in Austria and Zermatt in Switzerland.
Further markings on groomed slopes
It is easy to lose your bearings in large ski areas, which is why groomed slopes are often marked to show the way.
If a ski area is to receive a slope quality seal, arrows are placed at the edges of the slopes.
In addition, poles and signs are set up along the slopes, either in fluorescent colors or in the respective slope color, to mark the direction of travel or the training area.
No markings in open terrain
If there are no more signs in sight, then you have left the secured ski area and are skiing in open terrain.
This area is neither marked, groomed nor secured.
Anyone leaving the marked pistes should be aware that they are doing so at their own risk.
When leaving the slopes, the danger of avalanches or falls is often indicated, for example by signs with an avalanche warning.
In many cases, an orange flashing light also indicates the current avalanche danger.
Conclusion
The slope markings in ski resorts are used for orientation and indicate the level of difficulty of the slopes. Green slopes are ideal for beginners with a gentle gradient of up to 25 percent, while blue slopes are also suitable for beginners and families, but are somewhat steeper.
Red slopes are aimed at advanced skiers with a gradient of less than 40 percent, and black slopes are only suitable for very experienced skiers as they have a gradient of over 40 percent.
Ski routes, which are often unprepared, offer adventurous skiers additional challenges.
The markings help you to find your way around the ski area safely and avoid dangers such as unsecured terrain.
