Runs, Lifts, Variety and Parks
Trail closures, price
Simply put, Killington Vermont is one of the best resorts within a day's drive of half the U.S. population. With 6 mountains plus another resort called Pico that can be ridden with the same lift ticket, you are looking at a week's worth of riding without hitting the same run twice. The long groomers are incredible, such as Great Eastern, which takes a good 20 minutes top to bottom, and that is riding fast. The steep runs here are incredible, except for the few that don't get groomed (however this is subject to opinion as I am a snowboarder and don't enjoy moguls). There is plenty of different black and double black terrain that will make your legs burn. The canyon area is awesome for this type of riding, with steep groomed runs, trees and park all right there.
The terrain parks here are awesome, complete with any feature that you've ever hit. Worth noting is the Stash, which is a unique park made entirely out of natural material. They can take awhile to open these parks however, so checking the website (killington.com) helps if you are planning a trip around this.
Many people end up complaining about the price of a lift ticket (around 84 USD on weekends), but when you look around at all that Killington has to offer, you really can't complain, as this price has become the norm at many large scale mountains. And besides, we went last week for 50 dollars a day by purchasing tickets from an online lift ticket site. But definitely bring your own food, unless you enjoy paying ten bucks for a turkey burger, fries not included.
All in all, I have never left Killington unsatisfied. As long as around 100 trails are open (usually by early January) you will never get bored, between tree riding, long groomers, steeps and parks. If you are a serious skier/rider and do not have a set destination for your next trip, I strongly recommend looking into Killington. You won't regret it.
