Diamond Mountain District, located between downtown Calistoga and the forested slopes of Diamond Mountain, is a residential and resort-adjacent Calistoga neighborhood with vineyard edges and geothermal spa culture. The neighborhood’s character concentrates along Lincoln Avenue near Washington Street, where tasting rooms, small galleries, and sidewalk cafés set a relaxed, walkable rhythm. Calistoga Spa Hot Springs, Indian Springs Calistoga, and the Sharpsteen Museum act as local pillars for soaking, design-forward hospitality, and town history. Architecture leans to Craftsman cottages, ranch homes, and low-slung contemporary retreats tucked behind mature landscaping. Bike routes and quiet lanes trace toward trailheads and winery roads, while evening light settles over the Palisades. The pace stays calm, with weekend foot traffic drifting in from the main street scene.

Own wine country! Perched in the reknown Diamond Mountain AVA is 4.56acres of paradise. The Diamond Mountain District AVA is an American Viticultural Area located in California's Mayacamas Mountains in the northwest portion of the Napa Valley AVA. The appellation sits at a higher elevation than most of Napa Valley's wine region, resulting in less cool fog coming in from San Pablo Bay, and more direct exposure to sunlight. The soil of this AVA is volcanic and very porous which allows it to cool down quickly despite the increased sunlight. Tuck yourself in and enjoy the modern updates of your quaint 1940's cottage while you plan the development of your dream home. Capture 360dergee views of Vineyards, canyons & mountains with a spectacular new build designed for you. This little slice of heaven is waiting for you.
