Mosswood Hollow, nestled on forty acres in the foothills of the Cascade Mountains, abounds in natural beauty and grace. 

Who Comes

We host a variety of workshops, conferences, group retreats, family reunions and celebrations. The events that frequent here are primarily between fifteen and thirty-five people, although we also host day events, larger celebrations, family reunions, and weddings of up to seventy-five. 

Spaces for gathering

Our thirty foot yurt comfortably seats up to forty in a circle and is an excellent environment for movement retreats/workshops such as yoga, Tai Chi, and guided meditation. Instructive workshops and conferences enjoy the great acoustics. 


There are overnight accommodations in the main lodge for up to twenty-two and open fields for camping. 



Provided meals are artfully prepared and presented with great care using whole foods, locally grown and organic whenever possible.
