This is well and truly on my bucket list!!! I used Castro Marim sea salt at home now I can float in the stuff! There is a quirky spa where you can coat yourself in the salt, have a massage using it or even float in the salt beds directly!
It looks quite tricky to find but it looks like just past Castro Marim, going in the direction of Vila Real de Santo António, on a narrow dirt road that goes to the left, you find the signs to the salt mines of Barquinha . Follow this track and you will find the Salt Spa.
