Billionaire Bill Koch’s 52-Acre Aspen Estate Just Hit the Market for $125 Million
- Billionaire businessman Bill Koch's 52-acre Aspen estate, Elk Mountain Lodge, featuring a main home, guest cabins, private ponds, and recreational trails, is on the market for $125 million.
A sprawling Colorado estate long owned by billionaire businessman, sailor, and avid art and wine collector William "Bill" Koch has just hit the market. Nestled amid a scenic alpine valley tucked in between Castle Creek and the peaks of the Elk Mountains, about 10 miles outside of downtown Aspen, the 52-acre spread with a main home, several guest cabins, and a wealth of recreational pursuits is armed with a hefty $125 million price tag.
"You won't find an opportunity to build this scale of square footage again in Aspen," says Steven Shane of Compass, who holds the listing . "With private ponds, hiking and cross-country skiing trails, and proximity to the vibrant heart of downtown Aspen, this is the ultimate multi-generational family legacy property."

Koch, founder of the Florida-based energy development holding company Oxbow Carbon Corporation and a member of the ultra-wealthy family behind the crude oil-gathering conglomerate Koch Industries , paid $26.5 million for the former dude ranch in 2007. He went on to transform an existing event venue into a private retreat and also acquired an additional 31 acres before hoisting the entire 82-acre spread up for sale in 2015 at $100 million; the price was later dropped to $80 million. After selling the 31-acre portion of the property in 2020 for $14.5 million, he took the remaining 52-acre parcel with a lodge off the market and floated it for rent at $35,000 per night or $300,000 a week.
Nestled on Rooney Circle, a private road named for his wife Bridget Rooney Koch, the compound is known as Elk Mountain Lodge and features a main residence, plus seven guest cabins—for a combined total of 14 bedrooms and 17 baths in almost 25,300 square feet.
In addition to hiking and cross-country ski trails, the 52-acre spread sports two hot tubs.

Seven bedrooms and eight baths can be found in the primary dwelling, which has a little more than 16,600 square feet of rustic living space boasting flagstone floors, 30-foot ceilings, wood-paneled walls, and numerous fireplaces. In addition to a 20-seat dining room and climate-controlled wine storage, other highlights include two studies and a screening room that doubles as an altitude-acclimation chamber. The largest of the seven cabins currently houses a gym, with other amenities including a pair of hot tubs, ponds, and hiking and cross-country ski trails throughout the estate.
Per The Wall Street Journal , which first reported the listing, Koch has homes in New York City, Palm Beach, Fla., and Cape Cod. He also lays claim to the roughly 4,500-acre Bear Ranch in Paonia, Colo., where he created a multi-building replica of an Old West town.
