The Crombie Arboretum
18900 Armstrong Woods Road | Guerneville, California

Discover The Crombie Arboretum — a rare 120-acre redwood sanctuary in Guerneville featuring globally sourced conifers, curated forest trails, a pavilion-style residence immersed in nature, and extraordinary future estate potential.

A Sanctuary Hidden Beyond the Redwoods

The pavilion residence rests quietly beneath towering redwoods, offering an immersive connection to the surrounding forest landscape.

Hidden beyond a gated private road near Guerneville, The Crombie Arboretum unfolds across approximately 120 acres of extraordinary redwood forest, curated botanical landscapes, open meadows, and peaceful woodland trails.

More than a private property, this is a living sanctuary — a place shaped over decades through stewardship, vision, and a profound respect for the natural world.

Towering redwoods frame the arrival experience, while rare wild-origin conifers sourced from nearly every continent where conifers naturally occur create an environment unlike anything else in Northern California. The result is both deeply serene and globally significant — part private retreat, part living arboretum.

At the heart of the property, a pavilion-style residence sits quietly within the landscape, designed to immerse daily life within the beauty of the surrounding forest.

The Living Arboretum

The Crombie Arboretum reflects decades of botanical vision, stewardship, and the thoughtful cultivation of rare conifers from around the world.

More than a private estate, the property represents a long-term botanical vision developed through stewardship, cultivation, and careful placement of rare conifer species sourced globally.

Over more than two decades, The Crombie Arboretum evolved into a remarkable private collection of rare wild-origin conifers sourced from across the globe — representing nearly every continent and climate where conifers naturally occur.

Thoughtfully introduced into the coastal redwood environment, the collection reflects years of horticultural vision, irrigation development, botanical stewardship, and careful adaptation to the property's unique microclimate.

Towering redwoods remain the dominant canopy, while rare specimen trees from Asia, Europe, the Americas, and beyond quietly unfold throughout the landscape — creating moments of surprise and discovery along the property's meandering trails.

Unlike traditional gardens designed for a single moment in time, arboretums mature slowly and become more meaningful with each passing year. Here, the landscape itself tells a continuing story of patience, exploration, and reverence for the natural world.

FOREST TRAIL ROAD-Arrival Into the Landscape

Forest roadway winding through curated woodland terrain.

A network of maintained roads and pathways gently guides movement throughout the property, revealing changing woodland perspectives, open forest clearings, and hidden moments within the landscape.

Hidden Moments Within the Landscape
Throughout the arboretum, quiet pathways lead to secluded spaces thoughtfully woven into the natural landscape.

The property was designed to be experienced gradually — through movement, discovery, and immersion. Trails and pathways connect the various botanical areas while preserving the quiet natural rhythm of the landscape.

Beyond the primary trails, smaller pathways quietly branch into intimate spaces designed for reflection, observation, and connection with the surrounding environment.

The land itself feels alive with movement and renewal. Seasonal water flows, mature woodland canopy, and the property's connection to the greater Russian River watershed contribute to the vitality of the surrounding ecosystem.

Supporting the arboretum is an established water infrastructure centered around a private well that historically tested at approximately 19 gallons per minute, along with multiple water holding areas and irrigation systems developed over years of stewardship and cultivation.

Together, these elements support not only the rare botanical collection, but also the enduring sense of abundance and sustainability that defines the property experience.

Living Within the Forest

Designed to immerse daily living within the surrounding landscape, the pavilion residence features expansive windows on multiple sides that draw natural light and forest views into the interior spaces.

Designed to dissolve the boundary between architecture and nature, the pavilion residence is wrapped in windows overlooking the surrounding forest landscape. Natural light enters from multiple directions while the redwood environment becomes part of the living experience itself.

At the heart of the arboretum, the pavilion-style residence was thoughtfully positioned to create a seamless relationship between architecture and nature.

From nearly every vantage point, the landscape remains present — towering trees, shifting sunlight, and the quiet rhythms of the woodland environment becoming part of daily life itself.

The residence offers an atmosphere that feels both grounding and restorative, designed less as a traditional home and more as an immersive retreat experience within the redwoods.

Simple, open living spaces encourage a slower pace and a deeper connection to the natural surroundings, while the broader property offers extraordinary future potential for a larger legacy estate residence positioned among the forested hillsides and scenic viewpoints.

A Vision for the Future

Positioned among towering redwoods and filtered forest light, the premier estate site offers a rare opportunity to envision a future legacy residence immersed within the landscape.

In addition to the existing pavilion residence, the property presents extraordinary future potential through premier estate view sites positioned within the landscape. Open woodland clearings and elevated outlooks create an exceptional setting for a future legacy residence or retreat compound.

Here, open outlooks emerge gradually through the redwoods, revealing distant ridgelines, layered forest canopies, and changing light throughout the day. The setting feels remarkably private and deeply connected to the surrounding natural environment — expansive without sacrificing intimacy.

The estate site presents the opportunity to create a future legacy residence designed in harmony with the arboretum and broader landscape, whether envisioned as a private family retreat, architectural compound, wellness sanctuary, or multigenerational estate immersed within the forest.

What makes the opportunity especially rare is not simply the land itself, but the decades of stewardship already invested in shaping the environment surrounding it — mature conifers, established trails, irrigation systems, curated forest clearings, and the quiet sense of permanence that only time can create.

Exploring the Landscape

The illustrated property map provides a conceptual overview of the broader arboretum vision — connecting the residence, trail systems, botanical collections, scenic viewpoints, and future estate opportunities across the landscape.

Thoughtfully developed over time, the property unfolds as a connected landscape experience rather than a single destination.

Private trails weave through redwood groves, curated conifer plantings, scenic overlooks, open clearings, and peaceful gathering spaces — allowing the arboretum to be explored gradually and experienced differently throughout the seasons.

The illustrated landscape plan reflects the broader vision behind the property: a rare integration of architecture, ecology, stewardship, and long-term legacy planning set within the extraordinary natural beauty of the Northern California redwoods.

A Rare Opportunity to Steward Something Meaningful

Quiet gathering spaces throughout the property invite moments of reflection beneath towering redwoods and expansive forest views.

Throughout the property, specimen tags and curated plantings reflect the extraordinary botanical stewardship behind the collection. Rare conifers sourced from around the world were intentionally established within the coastal redwood environment over decades of care.

Properties of this nature rarely emerge through traditional real estate channels.

The Crombie Arboretum represents far more than acreage or architecture — it is the result of decades of thoughtful cultivation, ecological stewardship, botanical exploration, and long-term vision woven carefully into the Northern California landscape.

Here, the experience is defined not by excess, but by immersion: sunlight filtering through towering redwoods, winding trails through rare conifer collections, seasonal creeks, open forest clearings, and the profound quiet that only protected natural environments can offer.

Whether envisioned as a private retreat, future legacy estate, conservation-minded sanctuary, or multigenerational gathering place, the property offers an opportunity to become part of something enduring — a landscape shaped slowly over time and deeply connected to the rhythms of the natural world.

For those drawn to rare places with soul, history, ecological richness, and extraordinary future potential, The Crombie Arboretum stands as a truly singular offering within the California redwoods.
