Marine Mud

This mud comes from the natural heritage of the Bay of Mont-Saint-Michel.

Collected off the coast of the Chausey Islands, far from any pollution, filtered and micronised, particularly rich in trace elements, it is applied hot or cold, remineralising the body, treating rheumatism, draining oedemas and encouraging venous return.


The benefits of thalassotherapy

Thalassotherapy consists of providing treatments using 3 natural elements : sea water, mud and seaweed, and sea air.
It provides a good biological balance and it is quite natural for the body to recharge itself. The treatments, combined with a healthy diet and regular physical activity, act on health, sleep and stress for a lasting well-being.
Our physiotherapists and hydrotherapists will provide you with restorative or simply relaxing treatments, in a quest for overall well-being. 
Heated seawater allows the skin to absorb the minerals and trace elements that the body needs. It releases toxins, softens and strengthens muscles, improves and relieves joints. 
Seaweed and mud, taken directly from the bay of Mont-Saint-Michel, are very rich in organic and mineral matter, mineral salts and vitamins. Applied in wraps, they remineralise the skin, eliminate toxins and relieve the joints.
The sea air and the benefits of the invigorating Channel winds. Rich in trace elements, the sea air encourages the dilation of capillaries and accelerates exchanges between the human body and the marine environment. In contact with it, a tired body naturally recharges itself with negative ions and replenishes its mineral salts. From the very first days, stress disappears and the body regains a maximum of energy. 


The tides in the bay of Mont-Saint-Michel, the strongest in Europe, create violent currents that ensure the renewal of the sea water, its oxygenation and its richness in micro elements. They make Granville an ideal site to enjoy the virtues of thalassotherapy. 


A Prévithal cure is a unique health and well-being experience and an opportunity to enjoy the marine climate, its coastline and the spectacle it offers to our eyes, alone, as a couple or as a family.
