About the property

Diamond on the River — Private Pond, Water Right & Apartment

A genuine rarity in the Roaring Fork Valley — this Aspen Glen estate fronts the Roaring Fork River and includes its own pond and deeded water right. Set on just over 1.6 acres, the residence spans roughly 7,978 square feet and delivers a thoughtful sequence of rooms for family living and entertaining. The voluminous main living room frames the river through floor-to-ceiling glazing and anchors the plan with a spectacular two‑story stone fireplace; adjacent seating and dining spaces flow into an open family kitchen that invites gatherings around the island bar. On the main level the enormous primary suite features a private sitting area and deck overlooking the water, providing a sweeping vantage for sunrise and evening river activity.

Practical luxury is found throughout: five ensuite bedrooms, a stately home office, a dedicated meditation and exercise room, and an upstairs/lower-level plan that offers privacy for guests. The lower level functions almost like a separate wing with its own family room, kitchenette, access to the patio and fire pit, and direct river access — perfect for multi-family living or for hosting friends. A separate apartment with private entrance increases flexibility for rental income, live-in staff or extended family.

Outside, the property’s river frontage, private pond and water right are the headline features that set this parcel apart from most valley offerings. A fly-fishing room and easy wader access let you step directly onto a stretch of Gold Medal water; bald eagles and abundant river wildlife are frequent visitors to the bank. Landscaping and multiple patios create outdoor rooms for dining, evening fires and quiet contemplation of Mt. Sopris across the valley.

Aspen Glen residents may opt into the private club and enjoy a Jack Nicklaus-designed course, fitness center, pool and pickleball — membership is optional. Downtown Carbondale and the Willits retail district (including Whole Foods) are a short drive for everyday needs, while Aspen/Snowmass world-class skiing and two regional airports are approximately a 45-minute drive. This property is offered at $5,250,000 — a rare riverfront opportunity combining scale, privacy and true water assets.

The area attracts buyers seeking mountain lifestyle with lower valley access to restaurants, independent shops and outdoor recreation. Carbondale offers a strong local arts scene, farmers markets and convenient services while Aspen and Snowmass remain within easy driving distance for seasonal recreation.

Editorial market perspective

True riverfront parcels in the Roaring Fork Valley trade in a distinct sub-market from standard single-family inventory. Supply is extremely limited and demand remains steady among high-net-worth buyers seeking fishing access, mountain recreation and privacy. Median local sale prices for mid-valley homes are materially lower than this listing, but true riverfront estates with water rights command premiums. Expect a selective buyer pool, seasonal variability in showings, and marketing time measured in weeks to a few months depending on price alignment and contract conditions. Sellers should emphasize documented water rights and riparian access; buyers should be prepared for due diligence on water and environmental restrictions.
