We’re closing in on the end of December, and winter weather is in full effect across the country.

For some of us, that means hanging out in front of a fireplace and sipping warm, boozy drinks. But for others, the first signs of snow are an invitation to grab skis or snowboards and hit the slopes.

I have to admit that, more often than not, I fall into the former camp (and even when I do head to the mountains, this is more my style). But a lot of my friends are ski bums, and for them, there’s a really interesting new way to feed their addiction: Liftopia.

A startup that offers deep discounts on lift tickets at more than 150 ski areas, Liftopia is a no-brainer for anyone planning a ski trip: simply search for deals in the area you want to visit on the dates you’re hoping to travel, and the site returns a list of offers at markdowns of up to 80%.

The company recently launched an iPhone app that lets users find instant deals near their current location, or browse other areas and dates, just like the web app.

In addition to Liftopia’s core offering, the service also provides weather reports, directions to ski destinations, and deal alerts for your favorite spots.
