Introducing a once-in-a-lifetime opportunity to claim one of the most significant, versatile pieces of land in Boulder County. At 0 Rozena Drive, over 31 pristine acres offer a rare canvas to bring your legacy vision to life, centered around a private 16.6-acre, spring-fed lake. A personal body of water of this scale, held in its entirety, is nearly impossible to come by in the Front Range. For the sportsman, the lake is a world-class asset, teeming with elite fishing opportunities. Trophy catches have included 27" bass, 17" crappie, bluegill, channel catfish, and more, all from your fully owned shoreline. Beyond the main lake, a secondary pond fed by the Longmont Irrigation Ditch expands both recreation and water stewardship. The water invites swimming, paddle boarding, boating, and more, all set against show-stopping views. Encircling the shoreline, a wide, picturesque path winds through the parcel, creating an ideal circuit for trail runs, sunset mountain bike rides, or quiet mornings of bird watching and nature photography. Immerse yourself in a thriving ecosystem that feels worlds away, yet sits just minutes from the vintage Colorado charm of Hygiene. The build potential is equally compelling, with a designated envelope allowing for up to 6,500 square feet of residential space positioned directly along the shoreline, offering uninterrupted views of Longs Peak. Every inch of this acreage is oriented to capture the surrounding landscape, ensuring your future home is framed by some of the most iconic vistas in the American West. Enjoy a rare balance of privacy and accessibility, with easy access to local favorites like The Mountain Fountain and Cafe Fritz, and close proximity to the vibrant energy of Boulder and Longmont. This is a singular opportunity to create an enduring Colorado legacy.
