    What's special

    Extensive forest trailsPremier view build siteGlass-walled pavilion guest residencePavilion guest residenceSecluded roadEstablished irrigation systemGated approach
    A Private Redwood Botanical Estate Set beyond a gated approach at the end of a secluded road, this remarkable offering combines a pavilion guest residence, a globally sourced conifer collection, extensive forest trails, and a premier view estate building opportunity within a serene redwood landscape. The property unfolds within the Crombie Arboretum, a privately established and curated collection of rare, wild-origin conifers sourced from around the world. Developed over more than two decades and thoughtfully supported through its early years, the collection now stands as a mature and thriving botanical environment representing species from every continent where conifers naturally occur. A charming glass-walled pavilion guest residence is positioned within the landscape, offering an immediate connection to nature and a peaceful retreat immersed in forest surroundings. Extensive trails, maintained over decades, wind throughout the property beneath towering redwoods and mixed forest, inviting exploration and quiet reflection. An established irrigation system initially supported the curated plantings and ongoing stewardship of the land. In addition to the guest residence, the property features a premier view build site, offering the opportunity to design and create a legacy estate within this extraordinary natural setting. Access is provided via a private road through a protected forest corridor. Located just minutes from Guerneville and the Russian River, yet offering a profound sense of privacy and stillness, this is a rare offering where botanical significance, seclusion, and long-term vision come together. Shown by appointment ONLY.
