Ski slope ratings are used to classify slopes based on their difficulty level, helping skiers choose the appropriate slope for their skills and experience – but it’s not always so clear cut.
I’ve skied in Asia, Europe and the East and West Coasts (a little in the middle but does that count?) of the USA and I can confidently tell you that I’m obsessed with ski slope ratings because I’m a mid-level skier and never want to become expert.
i.e. I don’t want to get caught somewhere scary.

Ski Slope Ratings Key Takeaways
- Understanding ski slope ratings is essential for every skier to ensure their safety on the slopes.
- In USA Beginner level slopes are marked with green circles, intermediate level slopes with blue squares, and advanced level slopes with black diamonds.
- In Europe there’s a also “red” and “orange” to make it more confusing.
- Ski slope ratings can vary between ski resorts, so it’s important to check the ratings for each individual slope before skiing.
- While these ratings should be across the board, beware that sometimes they aren’t regulated perfectly.
❌ SO I NEED to know which runs I can enjoy and not end up taking off my skiis and sliding down on my butt.
And, yes. It’s different in Europe. They have reds and oranges that aren’t used in USA. They also have a lot of “off-piste” that is NOT backcountry skiing.
We always call it an “Austrian blue” meaning it’s really red (in Italy the exact same run would be classified as more advanced). Those people are born with zero fear (yes, I’m jealous).
Read until the end where I share the difference between Europe and USA ski slope ratings.
Quick Take Ski Slope Ratings:
Are the ratings legit? Only somewhat and it’s highly varied. Beginner level slopes are generally marked with green circles, intermediate level slopes with blue squares, and advanced level slopes with black diamonds.
So let’s be honest. You’re reading this because someone really good at skiing wants you to go and you’re not sure about any of this.
And you probably don’t want to get stuck at the top of a lift and scared to go down something too aggressive but you want to get off the bunny hill.
The ratings are based on several factors, including slope gradient, trail width, and the presence of obstacles such as trees and rocks. It’s important to note that ski slope ratings can vary between ski resorts, so it’s essential to check the ratings for each individual slope before skiing.
Ski Slope Ratings
When it comes to skiing, understanding ski slope ratings is essential. Ski slope ratings are used to indicate the difficulty of a ski run and help skiers choose a run that is appropriate for their skill level.
The rating system is typically used in North America and Europe, and while the rating systems may differ slightly between countries, the general principles are the same.
Rating System
The rating system for ski slopes is based on the steepness of the run, the width of the trail, the presence of obstacles, and the snow conditions. The rating system uses a series of symbols and colors to indicate the level of difficulty of a run. The most common rating system uses green circles, blue squares, black diamonds, and double black diamonds. Green circles indicate beginner runs, blue squares are intermediate runs, black diamonds are advanced runs, and double black diamonds are expert runs.
Ski Slope Ratings: Pros and Cons
- Ease of Communication
- Set Expectations of Difficulty
- Easy to Read Signs
- Highly Subjective
- Overconfidence Risk
- Changes with Time and Conditions
Ease Communication
Slope ratings provide an easy way for resorts to communicate difficulty levels to skiers of different abilities. Someone of any experience can understand at a glance what a green, blue, or black slope entails.
Set Expectations
Ratings help skiers set expectations for what they’ll encounter on different runs, as explained in the Peak Rankings article. Beginners know to avoid blacks and experts know greens won’t challenge them.
Subjectivity Issues
However, ratings rely on subjectivity and can vary between resorts. This means the challenges may not be consistent for runs with the same color.
Changes Over Time
Conditions like weather, grooming, and traffic can impact the real difficulty on a given day. A run rated blue may be harder or easier than normal.
Overconfidence Risk
Skiers familiar with one resort may get overconfident on similarly rated runs elsewhere. The actual terrain could be deceptively more challenging.
Beginner Level Slopes
If you’re new to skiing, then beginner level slopes are the perfect place to start. These slopes are designed for first-time skiers and are marked with green circle symbols on trail maps. In this section, we’ll cover everything you need to know about skiing on beginner slopes.
Green Circle Slopes
Green circle slopes are the easiest slopes on the mountain, and they’re perfect for beginner skiers. These slopes are marked with green circle symbols on trail maps and are typically wide and gently sloping. They’re also usually groomed regularly to provide a smooth surface for skiing.
Wide and Groomed Slopes
One of the best things about beginner slopes is that they’re usually wide and groomed. This means that there’s plenty of room for you to practice your turns and control your speed. The groomed surface also makes it easier to ski, as you won’t have to worry about skiing over bumps or uneven terrain.
Resort Facilities for Beginners
Many ski resorts have dedicated facilities for beginner skiers. These facilities often include magic carpets or beginner lifts, which are designed to make it easier for you to get up the mountain. They may also have separate beginner slopes, so you won’t have to worry about more advanced skiers whizzing past you.
Safety Measures for Beginners
Skiing can be a lot of fun, but it’s important to stay safe on the slopes. Ski resorts take safety seriously, and they have a number of measures in place to protect beginner skiers. Ski patrol is always on hand to help if you get into trouble, and many resorts have safety signs and markers on the slopes to keep you informed of any hazards.
Learning and Progression
The key to becoming a better skier is to keep learning and practicing. Beginner slopes are the perfect place to start, and you can work your way up to more advanced slopes as you improve. Ski schools are also available at many resorts, and they can help you learn the basics of skiing and progress to more advanced techniques.
Trail Map Symbols for Beginners
Trail maps can be confusing, especially if you’re new to skiing. Beginner slopes are marked with green circle symbols on trail maps, so be sure to look out for these symbols when planning your route.
Beginner Slopes in Different Regions
Beginner slopes can be found at ski resorts all over the world. North America, Europe, Japan, and Canada all have great beginner slopes, so you’re sure to find a resort that suits your needs.
Beginner Skiing Techniques
When skiing on beginner slopes, it’s important to focus on your balance and control. Try to keep your weight centered over your skis and use your edges to control your speed. Work on perfecting your turns and practice carving and parallel turns as you progress.
Hazards on Beginner Slopes
While beginner slopes are generally safe, there are still hazards to be aware of. Rocks, trees, and other obstacles can be dangerous if you’re not paying attention, so be sure to stay in control and keep an eye out for any hazards on the slopes.
Snowboarding on Beginner Slopes
If you’re interested in snowboarding, then beginner slopes are a great place to start. Many resorts have dedicated beginner terrain parks, which are designed specifically for snowboarders. Be sure to rent a snowboard and take a lesson to learn the basics before hitting the slopes.
Terrain Parks for Beginners
Terrain parks are areas of the mountain that are specifically designed for skiers and snowboarders to practice tricks and jumps. Many resorts have beginner terrain parks, which are perfect for first-time skiers and snowboarders.
First-time Skier Tips
If you’re skiing for the first time, then there are a few things you should keep in mind. Dress warmly and in layers, wear a helmet, and be sure to take lessons to learn the basics of skiing. Don’t be afraid to ask for help, and remember to take breaks when you need them.
Intermediate Level Slopes
As an intermediate skier, you’re ready to tackle more challenging terrain than the green circle slopes, but you’re not quite ready for the black diamond runs. Intermediate slopes are marked with blue squares in North America and Europe, and blue trails in Japan. These slopes offer a good mix of steepness, obstacles, and terrain features to keep you engaged and challenged.
Blue Square Slopes
Blue square slopes are the bread and butter of intermediate skiing. They offer a good mix of groomed runs, moguls, and varied terrain. These slopes are perfect for intermediate skiers who want to work on carving and parallel turns. Some blue square slopes may have steeper sections or more obstacles, so be sure to check the trail map before heading down.
Moguls and Bumps
Moguls and bumps are a common feature on intermediate slopes. These are mounds of snow that form naturally or are created by grooming machines. Skiing moguls is a great way to improve your balance and technique. Start by skiing around the bumps, then try to make short turns over them. As you get better, you can start linking turns and skiing faster.
Off-Piste Skiing for Intermediates
Off-piste skiing refers to skiing outside of marked trails. While it can be dangerous, it can also be a lot of fun. Many ski resorts offer guided off-piste tours for intermediate skiers. These tours take you to unmarked areas of the mountain where you can ski through powder and trees. Be sure to follow the guide’s instructions and never ski alone.
Intermediate Slopes in Different Regions
Intermediate slopes can vary depending on the region. In North America, intermediate slopes tend to be groomed and have a lot of terrain features. In Europe, intermediate slopes may be steeper and have more moguls. In Japan, intermediate slopes tend to be narrower and have more trees. Be sure to research the ski resort you’re visiting to get an idea of what to expect.
Intermediate Skiing Techniques
To ski intermediate slopes, you’ll need to master some basic techniques. Carving is an essential skill for intermediate skiers. This involves using the edges of your skis to make turns. Parallel turns are also important. This involves keeping your skis parallel to each other as you turn. Other techniques to work on include pole planting, weight distribution, and speed control.
Hazards on Intermediate Slopes
Intermediate slopes can have hazards such as rocks, trees, and steep drop-offs. Be sure to stay within the marked boundaries and follow the signs. If you’re skiing in a new area, take it slow and scout out the terrain before heading down. Always wear a helmet and other protective gear.
Snowboarding on Intermediate Slopes
Snowboarders can also enjoy intermediate slopes. Many ski resorts have terrain parks specifically designed for snowboarders. These parks have features such as jumps, rails, and boxes. Be sure to start small and work your way up to more challenging features.
