Near Harbin Hot SpringsNapa Valley | Lake County, CA
Welcome to Hidden Knoll — a private 5-acre volcanic mountaintop 1,250 feet above Napa Valley wine country.
Located just 8 miles from Harbin Hot Springs and 12 miles from Napa Valley, our land offers panoramic mountain views, dark sky, and true quiet — about 2 hours from San Francisco or Sacramento.
Far enough to feel like another world. Close enough for a restorative weekend.
Surrounded by oak forest, open space, and wilderness, this is where guests come to slow down, sleep deeply, and connect.
🌄 Mountain Volcanic Views
From the top of the knoll you can see:
• Mount St. Helena
• The full Mayacamas Mountains
• Harbin Mountain
• Steam rising from The Geysers
Sunrise over Angwin.
Sunset behind volcanic ridges.
Clear Milky Way skies at night.
Lake County is known for exceptional stargazing thanks to low light pollution and clean air.
🛖 The Glamping Experience
Each glamping site is spaced 150+ feet from the main farmhouse and bordered by 5 acres of oak forest for privacy.
We live on the property and steward the land, but guest areas are separate and peaceful.
Fully equipped glamping — not basic camping.
