Indulge in the soothing ritual of hydrotherapy.
Our outdoor hot spring pools and polar plunge pool offer more than a moment of relaxation: they invite you into the time-honoured practice of contrast hydrotherapy. Alternating between hot and cold water supports circulation, eases muscle tension and promotes a sense of renewal. At Millcroft Inn & Spa in Caledon, Ontario, guests can experience increased energy, improved circulation, relief in muscles and joints and a deeper state of relaxation, all within a serene natural setting.
Soak in Restorative Warmth
A defining feature of the Millcroft experience, our outdoor hot spring pools invite deep relaxation in a serene natural setting. Two pools are maintained at approximately 104°F (40°C), allowing guests to fully unwind while surrounded by the tranquil landscape of our grounds. The soothing warmth of the water helps ease muscle tension, calm the mind, and encourage a slower, more restorative pace.
Awaken the Sense with a Cold Plunge
For a more invigorating contrast, our polar plunge pool is kept at approximately 45°F (7°C). This refreshing immersion helps stimulate circulation, boost energy and awaken the senses—offering a revitalizing complement to the warmth of the hot springs.
