Salt Room in Boulder
Step into the salt room at The Dragontree Sanctuary and enter a space of luminous calm. Surrounded by warm salt walls and a soft, amber glow, you are invited to settle in, breathe deeply, and let the pace of the day fall away.
The salt room is part of the complete Sanctuary experience on Broadway in Boulder, alongside the cedar sauna, cedar hot tub, steam room, cold plunges, and forest showers.
A quiet place to simply be
The salt room offers a gentle pause within your Sanctuary journey - a place for stillness between the warmth, water, and invigorating cold.
Rest in silence, reconnect with a friend, or close your eyes and drift for a while. Nothing is expected of you here.
What to expect in the salt room
Halotherapy simply means resting in a room where fine, dry salt is dispersed into the air. Visit the salt room whenever you feel drawn to a quieter moment. Begin your session here to arrive more fully, pause between rounds of heat and cold, or return at the end to let the experience settle.
Your 90-minute Sanctuary Session gives you the freedom to move slowly and follow what feels most restorative.
Rest between heat and cold
After the sauna, steam room, or hot tub, the salt room offers a peaceful place to cool down before your next experience. Let your breathing soften, notice the warmth lingering in your body, and take all the time you need.
