groups & weddings

collective effervescence

KOSA offers space for connections in our 4,500 square foot space at the historic Garver Feed Mill. We have special packages for groups, wedding parties, and other events to benefit from this spirit of connection.

Our promise is an experience like no other spa or event space can offer, with a deep retreat in only a few hours. We nurture, ground, open, and transform. We find this energy creates a "collective effervescence".

The group packages include selections from our menu. See Offerings for reference. In addition, we offer add-ons with our partners, including hair, makeup, photography, and overnight lodging at our boutique hotel and B&B partner locations.

Please call us to book your group. We look forward to hosting this special occasion with you.

forest bathing retreat add-on

2 hours - $150/person; 3 hours - $225/person

Choose to start your group retreat time going inward and grounding with a ritual in nature. Shinrin-Yoku, immersing oneself in Nature, also known as "forest bathing," opens and activates the senses, helps one find stillness, just BE-ingness, and healing. Through a series of Nature-connection invitations, Shinrin-Yoku Madison's Kate Bast, a certified Nature and Forest Therapy Guide, leads you on a silent, slow-moving therapeutic walk in the season's woods to help you get out of your mind and into your senses. You will find deep calm, enhanced well-being, and a sense of connectedness--to Nature, yourself, and the world.

After this tranquil journey (near the Garver Feed Mill), come to KOSA for one of our Group Retreat packages with a new sense of self, ready to connect and receive.
