Rare riverfront retreat on a scenic bluff overlooking the Big Sioux River and Klondike Falls, just 20 minutes outside Sioux Falls. An unmatched natural setting with frequent bald eagle sightings and panoramic water views. Built with authentic 1900s reclaimed Southern Yellow Pine and custom handmade cabinets, this property serves as an incredible private getaway that can also help pay for itself—backed by an established 8-year short-term rental track record to offset your ownership costs. The home offers 1,850+ finished sq ft and 3 beds, 2 baths across two functional levels. The main floor great room features vaulted timber ceilings, solid hardwood floors, an entertainer's granite island, and floor-to-ceiling glass framing the river rapids below. Walk out onto the covered upper deck to take in the sound of the falls, or head downstairs to the walkout lower level complete with a second living room, two bedrooms, full bath, and a concrete patio with a private hot tub. An oversized finished 2-stall garage easily handles vehicles plus kayaks, fishing setups, and river gear. Additional Opportunity: The north adjacent 150' x 75' blufftop lot (1817 Ashley Ave) is available exclusively for purchase with 1823 Ashley Ave—providing immediate potential for guest cabins, a detached shop, or guaranteed view protection.
