Key takeaways
- A groomer is a ski run mechanically smoothed and packed by grooming machines (snowcats).
- It leaves an even surface, often with a corrugated 'corduroy' texture.
- Groomers are smooth, predictable, and ideal for carving, learning, and cruising.
- They're the staple terrain at resorts; the term can also mean the grooming machine itself.
What a groomer is
A groomer is a ski run that’s been mechanically smoothed and packed by grooming machines (snowcats) into an even, consistent surface — often leaving a corrugated ‘corduroy’ texture. The term refers to the groomed run itself (and sometimes to the grooming machine that makes it). Groomers are essentially the prepared pistes that make up most of a resort’s terrain.
Corduroy
The ribbed pattern grooming leaves in the snow is called ‘corduroy’, after the fabric it resembles. Fresh corduroy is prized — smooth, grippy, and predictable, ideal for carving clean turns, especially first thing in the morning before it gets skied off.
Arriving for first chair, a skier races to a freshly groomed run and lays clean carved turns down the perfect corduroy — the smooth, grippy surface letting their edges bite and hold, the morning’s reward before the run gets chopped up by afternoon.
Why groomers are great
Groomers offer a smooth, even, predictable surface that’s easier and more enjoyable than chopped-up or variable snow — ideal for beginners, carving, and cruising. They’re the staple of any resort and the smooth opposite of ungroomed moguls, powder, and crud.
The bottom line
A groomer is a machine-smoothed ski run — packed by snowcats into an even surface with a ribbed 'corduroy' texture — that offers the predictable, grippy snow ideal for carving, learning, and cruising. The staple terrain of any resort, fresh-groomed corduroy first thing in the morning is a skier's delight, and the smooth counterpart to ungroomed moguls, powder, and crud.
Frequently asked questions
What is a groomer in skiing?
A groomer is a ski run that has been mechanically smoothed and packed by grooming machines (snowcats) into an even, consistent surface. The grooming process flattens out bumps and chop and leaves a corrugated, ribbed texture known as 'corduroy.' Groomers are the smooth, prepared runs that make up most of a typical ski resort's terrain.
What is 'corduroy'?
Corduroy is the corrugated, ribbed pattern left in the snow by the grooming machines, named for its resemblance to corduroy fabric. Freshly groomed corduroy is prized by skiers — it's smooth, grippy, and predictable, ideal for carving clean turns, especially first thing in the morning before it gets skied off.
Why are groomers good for skiing?
Because they offer a smooth, even, predictable surface that's easier and more enjoyable to ski than chopped-up, bumpy, or variable snow. Groomers are ideal for beginners learning to ski, for carving and cruising at speed, and for comfortable all-around skiing. They're the opposite of ungroomed terrain like moguls, powder, or crud, which is more challenging and variable.
