Set along the sunny side of picturesque Riverside Drive, this rare 1.6-acre mountain retreat offers an exceptional combination of privacy, water, flexibility, and easy year-round access. Although across from the South St. Vrain River, the river is beautifully present — seen and heard from the home and two south-facing balconies. A long-established waterway runs through the backyard alongside a peaceful pond, creating a lush, private outdoor oasis deeply connected to the landscape. Inside, the remodeled open kitchen features knotty alder cabinetry, granite counters, a large gathering island, and a dual-fuel oven, all framed by three large windows overlooking the landscaping. The living room's wood-burning fireplace is both a charming centerpiece and a capable heat source for the home, complementing the boiler system — and the screened-in balcony just off the living room is the perfect place to relax to the sounds of the river. The spacious main-floor primary suite is a true spa-like retreat, featuring a gas fireplace, bay window, steam shower, rough-in for a soaking tub, and a connected breezeway with 220V ready for a future hot tub. A secondary bedroom enjoys its own private balcony with river views. The walkout lower level offers a large third bedroom or family room with half bath, workshop with exterior entrance, attached one-car garage, and generous storage. A separate cabin with propane, electric, water, and septic opens wonderful possibilities as a guest retreat, studio, office, or potential rental — buyers should verify uses with Boulder County. A detached garage with carport provides space for vehicles and mountain gear, while satellite internet supports modern life and work-from-home flexibility. Both the main home & cabin enjoy easy paved-road access. All of this just 20–30 minutes from Lyons and Boulder, yet feeling like a world away — a rare opportunity to own space, sunshine, water, privacy, and flexibility in one unforgettable mountain property.
