Try Green Gulch Farm in Marin which is part of San Francisco Zen Center. They have a wonderful Japanese-style guest house and guests can join morning and evening meditation in the Zendo--or meditation hall. In addition, there are delicious vegetarian meals, beautiful gardens and great hiking. Go to www.sfzc.org for more information. Anon.
