The location seamlessly blends retreat living with ultimate convenience. You are steps from world-class hiking and biking trails right outside your door, yet just a scenic, short drive to historic Mill Valley with boutique shopping, dining, parks, and more. Bring your vision to capture this rare slice of Mill Valley paradise! Buyer is advised to independently verify and research all matters related to building, zoning, utilities, and the status/reactivation of any previous plan approvals with the City of Mill Valley.
Cascade Canyon, located between Old Mill Park and the Mount Tamalpais Watershed, is a wooded and hillside Mill Valley neighborhood with redwood-shaded lanes and creekside trails. The neighborhood’s character concentrates around the Old Mill Park and Cascade Falls trailhead, where hikers, dog walkers, and post-ride coffee runs set the daily rhythm. Shingled cottages and mid-century homes tuck into steep lots, with footbridges and stairways linking quiet streets. The Mill Valley Lumber Yard adds a design-forward cluster of local shops and patios. Sweetwater Music Hall anchors evenings with live sets, while the Mountain Home Inn marks the climb toward Panoramic Highway. Fog and filtered light give the canyon a calm, coastal feel.
