The most expensive listing in ski country (and one of the priciest in the country) is this $89.9 million compound owned by billionaire and history-aficionado William Koch. Koch bought the former wedding venue for a measly $26.5 million before converting it into a 15 bedroom, 24 bath estate complete with 55 acres of biking, hiking, and four-wheeling.

Jackson Hole is located in the richest county in the country, so it makes since that its real estate is also over the top. The Walton Ranch is now only $48.7 million (a far cry from its summer 2011 ask of $100 million), but the 1,848 acre ranch is still one of the priciest buys in the high country. Along with 3 miles of coveted Snake River frontage, the ranch boasts a 2,234 square-foot home, several barns, corrals, ranch buildings, and employee buildings.

This 45-acre Aspen property on Buttermilk Mountain includes plans for a 13,500 square foot main residence that's currently under construction.

Listed at $39,750,000, one of Tahoe's most expensive properties offers four bedrooms, five baths, and 8,694 square feet. There are some standard amenities, like a gym, spa, three fireplaces, and a two car garage, but in this architectural wonder you get lots and lots of glass. Expect glass walls, a five story glass elevator, a six story glass stairwell, a glass fireplace, and even glass doors. Northstar, Diamond Peak, and Mt. Rose Ski Areas are all a 20 minute drive away.

Located about 35 minutes from Schweitzer Mountain, Idaho's most expensive listing might also win the prize for the most antlers we've ever seen in a house (although this Florida condo is holding its own). Six different lakefront buildings sit on over 48 acres and the whole shebang costs a whopping $36 million. In total there are 14 bedrooms and 14 baths that combine, per the listing, to create "an authentic Western Native American ambiance."

This massive Deer Valley property, owned by billionaire and philanthropist Jon Hunstman, is one of the most expensive ski properties in America. It once cost $50 million but is now asking a much more reasonable $34 million for its 12 bedrooms, 16 bathrooms, and ever-practical 22 car garage.

The priciest listing in Snowmass wants $31.5 million for its 6 bedrooms and 9 baths on 82 acres. The home has 2 ponds, a swimming beach, an enticing private fitness gym, and the most professional-looking movie theater we've ever seen in a mansion.

The bright red kitchen in this $29 million Aspen abode may not be for everyone, but buyers will surely love its ski-in/ski-out location at Buttermilk and 360-degree views.

The third most expensive Tahoe listing on the market right now at $26,499,999 is actually 3 parcels set on 3 acres of land and with 220 feet of lake frontage.

The outdoor spaces in this 10,550 square-foot mansion are what really make this Aspen mansion seem worth its $24.995 million price tag. There are multiple terraces, a private pool, outdoor fire pits, and a sleek design that complements rather than competes with the home's gorgeous views.

Asking $24.6 million, this 9 bedroom and 14 bath home boasts 15,743 square feet and sits on a large 5.31 acre lot. The exterior looks fancy (there's even an outdoor fireplace/hot tub combo), but we're clueless about the inside. Per the listing: "interior photos are available for qualified buyers only." Well then.

Asking $23,750,000, this 6 bedroom 10 bathroom Aspen home takes a different approach than many ski chalets. Don't expect subtle beauty here, this 11,875 square foot mansion is all about the flash.

Another contender for best pool in Colorado, this Aspen mansion clocks in at $23 million for its 6 bedrooms and 10 baths. There's plenty of space in the 15,889 square-foot home, but our favorite part is the outdoor area with a pizza oven and 360-degree views.

Telluride's most expensive listing offers two residences and three lots, all with ski-in/ski-out access for $22 million. There's your standard amenities in the largest 6 bedroom, 7.5 bath mansion located near the ski area's Mountain Village, but our favorite is a one-lane bowling alley.

Montana's most expensive listing is this Swedish cope log home sitting on 525 feet of Whitefish Lake frontage. Asking a cool $22 million, the house is a relatively tiny 4,868 square feet with only 3 bedrooms and 3.5 baths, but the location and picture-perfect surroundings merit the high price tag.

This $21.9 million listing just might be Park City's most baller ski home, with 6 bedrooms, 10 baths, and a top-of-the-world location. Created and managed by Resorts West as Deer Valley's flagship "Ski Dream Home," ski chalets just don't get much cooler than this.

Asking $21.5 million, this listing in Big Sky, Montana has some truly terrifying taxidermy, but it also includes a crazy amount of land: 1,500 deeded acres.
