About This Home

An Exceptional Opportunity in the Heart of Castle Creek Valley. Discover a rare offering just minutes from Aspen, where convenience meets the tranquility of country living. Ideally positioned at the confluence of Castle Creek Valley and Conundrum Creek Valley--one of the widest and sunniest stretches along Castle Creek Road--this remarkable 3-acre property offers an unparalleled building opportunity in a truly breathtaking setting. With expansive, flat terrain and all-day sun from early morning through evening, this premier homesite invites you to design and build your dream residence exactly as you envision. If has been left to the Buyer to designate an activity envelope, which will provide flexibility for placement, allowing you to fully capture the surrounding natural beauty and panoramic views. Despite its rural feel, the property is located just 8 minutes from the core of Aspen, with the Aspen school bus conveniently stopping at the top of Conundrum Creek. Aspen Country Day is only 2 miles down the road. The land is well-suited for families, equestrian use, and those seeking space for dogs and outdoor living. Rich in history and natural significance, Conundrum Creek Valley is known as the spiritual valley of the Ute Indians, where journeys to the hot springs once marked a rite of passage. Owning this property will be your rite of passage.
The property includes a charming, 3-bedroom cozy cottage that may be used as a residence or rental during the construction of a new home. There is also potential--subject to Pitkin County approval--to retain the cottage as a Caretaker Dwelling Unit (CDU). Views extend up Conundrum Valley toward the backside of Aspen Highlands, and down the valley toward the striking red cliffs. Included is a well right, spring right and a pond right. Multiple building site options are available, with current allowances for approximately 5,750 square feet above grade. Additional square footage may be pursued through Growth Management or TDR processes. A future owner will complete site plan approval based on their preferred home placement. The property is well-equipped with valuable water resources, including an adjudicated spring, pond, and well. Existing infrastructure includes underground electric, propane, and septic systems. High-speed connectivity options are available via broadband, Dish, or Starlink. Enjoy the soothing sounds of Castle Creek just across the road and take in peaceful walks along Conundrum Creek Road beneath towering 100-foot Blue Spruce and Aspen trees or hike up to the Conundrum Hot Springs.
