Here are some helpful tips on ski slope etiquette, basically how to be less annoying when alpine skiing. These are behaviors best kept off the slopes, not to replace the 7 Point Skiers Responsibility Code, but to be a better skier socially. Here are things you should consider:
Don’t ski while talking on a cell phone, it’s like driving while texting. Skiing and riding require your full attention. 
Don’t crank your iTunes, blaring over your chairlift companions’ conversation. Aside from common courtesy, if you are so tuned out while skiing, you may not hear the approaching snowmobile or groomer. Also, please, no speaker phone – should go without saying?!
Don’t ski above your ability level. It is okay to challenge yourself, but it is not ok to endanger others by 
Don’t bomb straight down the trail just to reach the Terrain Park, make the most of your run, and your time in the park. Maybe it is just me, but I find it rude and reckless when park skiers just beeline to the park, cutting skiers off, then smear a big skid stop, producing a huge snow cloud to finally check their speed before the park entrance.
Don’t bomb through the Terrain Park, even though the best untouched cord lies on the 
Racers, the ski area does not exist solely for your run. Cutting lift lines and carving huge trenched arcs on your way to the race course with no regard to other skiers (people who paid full price for their lift privilege) is not very cool, despite your spandex suits and razor sharp skis. Assuming you are god’s gift to skiing is ill-advised. Very few of you, like .5%, will even enter the big leagues like US Ski Team’s Bode Miller, Lindsey Vonn, Mikaela Shiffrin. The rest of you will join the ranks of recreational skiers and hopefully find racer behavior annoying.
Lift lines: don’t enter the lift corrals until you are ready to ride said lift. See our Lift Line Etiquette Tips. Standing with your board or skis blocking the entrance jams up the flow. Floundering with your gear, trying to find your group, digging for your ticket to show the liftie, and missing chairs makes you look like a “Jerry on skis” – see our ski slang guide for your ski vocabulary. Causing the lift to stop because you did not slide out in time for the chair will not win you new ski friends.
Don’t attach your lift ticket to the front zipper of your jacket. It looks ridiculous, and worse, it whacks you in the face as you ski.
Don’t be a gaper; avoid the big gap between your goggles and helmet, or your hat and helmet – it looks silly and will subject your forehead to the cold, wind, sun, and ridicule.
Don’t assume you can just pick up the sport. Get a lesson, instead of teaching yourself to ski or getting a few pointers from your buddy. The money spent on professional instruction will reduce your risk of injury, improve your lifelong enjoyment of the sport of skiing, and accelerate your proficiency in the sport of skiing or snowboarding. We can all spot a self-taught skier by their technique (or lack of actually).
