Ski schools aren't just for beginners anymore. As part of an overall resort revival, ski mountains are pouring millions of dollars into their instructional and guiding programs. "People are asking for more personalized coaching," says Andy Buckley, director of skier services at Northstar in Lake Tahoe. "When you struggle with something technical, it's analogous to work and life stuff – the psychological barriers, getting over the hump. The best ski coaches turn into life coaches." These days it's not uncommon for your instructor to be a local legend or an Olympic medalist; some resorts are engineering their runs so they have just the right angles and aspects to learn on; cat- and heli-skiing trips now often include a full master class on evaluating snow conditions. These are the best mountains, ski schools, and guided adventures to help you raise your game.
