Welcome to Rivercliffe Ranch, an extraordinarily rare mountain retreat where luxury, privacy, and world-class fly fishing converge. Set on 2.85 secluded acres along the North Fork of the South Platte River, this custom-built 5-bedroom, 3.5-bath residence offers 3,816 finished square feet and was meticulously constructed in 1981 with exceptional craftsmanship and quality that is seldom found today. Rivercliffe Ranch is an exclusive five-owner enclave where each property includes a 20% undivided ownership interest in approximately 142 acres of permanently protected ranch land, ensuring unmatched privacy and preservation for generations to come. Owners enjoy private access to over two-thirds of a mile of the legendary North Fork of the South Platte River, renowned for its exceptional trout fishing, along with a private fishing pond and additional private creek frontage. The river itself is nothing short of spectacular, flowing through open meadow stretches before entering a dramatic canyon featuring deep pools, rushing rapids, and long runs that create outstanding habitat for trophy trout. Inside, the home offers generous living spaces warmed by two wood-burning stoves and a wood-burning fireplace, a two-car attached garage, and walls of windows that frame the river and surrounding mountain scenery. Whether casting a fly from your own backyard, relaxing beside the fire after a day on the water, or simply soaking in the serenity of this remarkable setting, this is more than a home—it is a legacy property that rarely becomes available. With only five ownership interests permitted and future development permanently restricted by conservation easement, opportunities to own at Rivercliffe Ranch are exceptionally rare.
