Osmosis Retreat


When the owner of Osmosis Day Spa & Retreat discovered the healing benefits of a Cedar Enzyme Bath in Kyoto thirty years ago he became inspired to create a sustainable spa business that was also based on principles of right-livelihood.

The meditative, detoxifying, and deeply rewarding experience that Osmosis offers begins with your immersion in a toasty, composty, highly enzymatic, and aromatic bed of wood chips. Spent an hour submerged in this hot and healing mulch of active enzymes and I dare you to have a harsh word to say about pretty much anything.

Osmosis also offers guests the rare opportunity to wander its lovely Kyoto-style meditation gardens including its own “constructed wetland’ based on principles of both aesthetics and permaculture.


Wander up the hilside to reap the resident vibe. For ten millenia or so, this area was the home of coastal Miwok and southern Pomo people and something of their loving attention to the land still lingers.

“When people don’t use plants they get scarce.
You must use them so they come up again.
All plants are like that. If they are not gathered from,
or talked to, or cared about, they’ll die.”

-Mabel McKay, Pomo Elder
