Take a tour of billionaire Bill Koch's 80-acre Aspen lodge, which can be yours for a discounted $80 million

Douglas Elliman Real EstateThe Elk Mountain Lodge compound is nestled in a valley just outside Aspen.

Billionaire businessman Bill Koch first listed this 80-acre property in upscale ski town Aspen for $100 million in 2015. Now, it’s received a $20 million price cut.

The historic property, called Elk Mountain Lodge, is a stunner just 10 miles outside of downtown Aspen. There are four parcels up for sale, totaling 28 bedrooms spread across 13 buildings in the pristine valley. Originally homesteaded in 1907 and converted to a dude ranch in the 1930s, the property was turned into an event space when Koch purchased it in 2007.

Bill, the youngest in the conservative Koch brother trifecta, is a real estate collector of sorts, with a compound in Cape Cod and a 6,400-acre ranch in Colorado, on which he built a private faux-Western town. He picked up the main Elk Mountain Lodge for $26.5 million in 2007 and then acquired the three neighbouring parcels. The whole package was put back on the block in 2014 at $90 million, but did not sell. In 2015, it was listed again for an eye-watering $100 million — easily Aspen’s most expensive listing ever, and one of the highest listing prices in the country as well. It’s now listed at the new price with Douglas Elliman Real Estate.

Take a look at the picturesque mountain escape, below.

Situated in a narrow valley between the Elk Mountains, the 80-plus acres have been everything from a homestead to a dude ranch to, most recently, an entertainment venue. There are four parcels in the Castle Creek Valley.
