About this home

A rare Sun Valley offering—this gated 52-acre estate spans two parcels with on-site geothermal water, sweeping Bald Mountain views, and direct access to untouched nature. A secluded forking canyon, accessible to almost no one else, enhances its sense of privacy. The property features a high-yield 20 GPM well and buried electricity for clean aesthetics and reliability. Just minutes from Sun Valley’s core, it offers the perfect blend of seclusion and convenience. Bordering Forest Service land, it’s a haven for wildlife—elk bugling in fall, ducks in spring, and deer year-round. Enjoy iconic sunsets over the bowls from this elevated retreat. Appraised at $10.2M in 2022, the private road is now being widened and improved. To view the full video tour, search the property address on YouTube.
