Imagine being able to experience this feeling of placid well-being amplified a hundred times, and in front of towering mountains, or in the desert, or in the forest, or surrounded by rocks: that’s what happens when you immerse yourself in the “Natural spas”, those places that nature has created in the world where water, warm and beneficial, flows directly from the heart of the planet, and creates-sometimes naturally, sometimes with the hand of man-pools that are an ‘injection of pleasure and well-being.

And not only that, in addition to being beautiful, they also do a lot of good. On a physical level, because the warmth and mineral richness are a panacea for the body, and especially on a mental level, because contact with nature is magic, the ingredients of which are good air and slow rhythms.

They bubble up from underground, are warm, soothing and surrounded by unspoiled nature: here are the world’s most beautiful natural spas!

Make yourself comfortable, sip an herbal tea-or relax in your bathtub at home-and follow us on this journey to discover the most incredible natural spas the Earth has been willing to give us.


Seen from the sky, the lagoon is a necklace of sapphires lying on the black velvet of the Icelandic wilderness, a color that enhances the blue of this natural geothermal source. It is so beautiful that National Geographic has included it in the 25 Wonders of the World: not only for the beneficial power of its mineral-rich waters, but also for the sophistication with which Icelanders have managed to create a structure that includes the Retreat SPA, a typical cuisine restaurant, a hotel with suites directly overlooking the basin, and private rooms carved out of volcanic rock, real Private SPA. All this, without affecting the natural beauty of the lagoon, but rather enveloping it as if in a protective embrace.

Designed to bring the mind and body into a new dimension of peace, the journey to the natural spa moves through the benefits triggered by the volcanic nature of the lagoon: exfoliation with mineral salts from the earth, treatment with an algae that grows only in these waters and then with silica, the lagoon’s iconic white mineral, culminating in the Blue Lagoon Ritual, immersion in the vapors of the source.

The Blue Lagoon has evolved, expanded to new horizons of wellness, but the turquoise waters that flow from the earth are still its heart and soul. And when you are there floating among the rocks, perhaps under the Aurora dancing in the sky, the water will take your mind and body and transport them to a world of wonder.

Spending a few hours immersed in these warm natural pools is a one-of-a-kind experience, both during the day, being able to admire the idyllic surroundings, and at night, illuminated only by the moon. Yes, because the natural spas of Mill Falls have a constant temperature of 37°C all year round, but more importantly, it is a natural and free place that is free and available at any time and in any season.

A narrow gorge in the mountains of Hidalgo state holds one of Mexico’s best-kept secrets: it is Tolantongo, a hot spring nestled between peaks and forests.
