Skiing comes in several different flavors. Groomers, moguls, sheer ice — the mountains can get pretty creative in terms of what they throw at skiers. Separating this massive roster of possible skiing conditions are two broader catch-all categories: on and off-piste. The former is manicured and generally safer; the latter tests skiers with challenging, variable terrain.

"Off-piste" is a term derived from the French word piste, which translates to track or trail in English. The phrase isn't as popular in the U.S. as it is in Europe, but generally, it refers to unmaintained, oftentimes expert areas. In the U.S., you might hear "off-trail" instead.
Due to their lack of grooming or preparation, the snow quality in off-piste areas can vary wildly. You may encounter bumps, ice, or, if you're lucky, fresh powder.

This variability in the terrain surface is part of the allure, but it also means that off-piste skiing requires stronger fundamentals. Groomed trails, in contrast, are easier to ski. At some ski resorts, in-bounds, off-piste terrain can be extremely tough, involving cliffs, chutes, and tight trees.
"Off-piste" is a more loaded term in the European context. Unlike in the U.S., skiing away from the groomed trails at many European ski resorts is similar to leaving the resort boundaries and entering the backcountry. Here, there may be backcountry hazards like unmarked cliffs and avalanches. U.S. ski resorts tend to delineate the difference between the backcountry and in-bounds areas clearly with orange rope lines and signage.
Backcountry skiing is any skiing that takes place outside of avalanche-controlled ski resort boundaries. Climbing up and skiing a mountain in a National Park? That's backcountry. So is shredding a snow-covered hill near town.
If you're interested in backcountry skiing, there are a few boxes you need to tick before traveling into the mountains outside ski resorts — each winter, on average, more than 100 skiers and backcountry travelers are killed by avalanches:
Sidecountry is a convoluted term that, in many cases, describes backcountry areas easily accessible from a ski resort's boundaries. The National Ski Areas Association (NSAA) now encourages the media and public not to use the phrase because, in their words, it "creates a false sense of safety" because "'sidecountry' is analogous to 'backcountry' in that it refers to terrain that is neither patrolled nor mitigated for avalanches."
To the NSAA — and others — sidecountry is backcountry with all the associated risks.
There is a wrinkle, though. Some resorts do have areas that blur the boundary between resort skiing and backcountry skiing. Alpental, Washington's Back Bowls, for instance, can only be accessed by skiers with avalanche rescue gear and a special pass. This zone, according to the resort, "is not managed or controlled for avalanches to the same extent as terrain in the developed ski area."
Terrain networks like the Back Bowls could also fall under the sidecountry umbrella, as they almost — but not quite — qualify as backcountry skiing. Alpental itself calls the Back Bowls "sidecountry."
What should you do with that admittedly confusing information? If you stumble across a gate at a ski resort, don't waltz through without asking a local or ski patroller about safety procedures first. It may lead into a controlled, relatively safe area — or it might lead directly into the backcountry where hazards like uncontrolled avalanche terrain exist. As always, know before you go.
