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.
