Our day at Osmosis was DELIGHTFUL! We arrived and were welcomed warmly by staff and directed to the changing rooms and the sitting room where we were offered a cup of tea. After our welcome tea, our first spa experience was the cedar enzyme bath, a practice rooted in ancient traditions. This was incredible! Josh, our attendee, was so great— supporting our treatment and keeping us hydrated. The cedar enzymes worked their magic, generating a gentle heat that steeped deep into my muscles and joints.
After the bath, our second experience was sound healing in the hammock garden. I felt so relaxed!
The combination of these treatments – the vibrational harmony of the sound healing hammocks and the detoxifying warmth of the cedar enzyme bath – was a journey into holistic well-being.

This is an amazing place for spa treatments. The healing atmosphere and wonderful staff and quality products give you the best bang for your buck. My favorite place for facials, massages and special events, such as the winter Solstice ceremony.
