More and more people are prioritizing wellness inside and out, and it is increasingly well known that seawater offers a wealth of health benefits. Here, in this corner of the Costa del Azahar, we are fortunate to have a true pioneer in utilizing seawater to enhance physical and mental well-being: El Palasiet.
This center, nestled at the foothills of the Desert de les Palmes Natural Park and overlooking the Bay of Benicàssim, has proven for decades that the sea is nature’s finest remedy for restoring vitality and boosting wellness—and if you live here, you can enjoy it all year round.
What thalassotherapy is and how it affects the body
The term originates from the Greek thalassa (sea) and therapeia (healing). Unlike a traditional thermal spa, where fresh or mineral spring water is used, a specialized center in this discipline works exclusively with seawater, sea algae, and marine mud.

The therapeutic power of seawater and hydrotherapy pools
For a seawater treatment to retain all its properties, the water must be drawn deep offshore, filtered, and heated to human body temperature, between 34 °C and 36 °C. At this temperature, the pores of the skin open and directly absorb minerals and trace elements present in the water, such as magnesium, potassium, and iodine.
Afterward, hydrotherapy pools combine this natural mineral input with the physical effect of pressurized jets, which stimulate circulation, relieve joint pain, and relax tense muscles.
What to expect on your first visit to a thalassotherapy center
If it is your first time enjoying a space like El Palasiet, the best approach is to arrive unhurriedly. Upon arrival, they provide you with the necessary gear, and you are attended by professionals who evaluate which circuits or jet pressures best suit your physical needs.
Unlike recreational jacuzzi facilities, the atmosphere here is completely quiet, aiming to help your nervous system wind down and allow you to relax to the fullest, thereby boosting the natural benefits of the treatment itself.
How a thalassotherapy circuit works step by step
Although each program can be customized, a standard routine follows a methodical sequence to maximize the benefits of every stage:
- Thermal seawater pool: An initial soak at around 36 °C to relax the muscles and initiate mineral absorption.
- Underwater jets and bubble beds: Targeted massage for key areas like the lower back, neck, and soles of the feet.
- Contrast baths: Alternating between warm and cold seawater to reactivate leg circulation.
- Saunas and saline steam rooms: Highly recommended for clearing respiratory airways and eliminating accumulated toxins.
- Relaxation lounge: Resting on heated loungers with herbal teas to stabilize body temperature before leaving.
El Palasiet: a benchmark among thalassotherapy spas in Spain
Founded in the 1970s by Dr. Joaquín Farnós, El Palasiet is much more than a holiday hotel. It was not created merely as a place to rest, but with a clear focus on preventative healthcare. That is why its facilities seamlessly integrate thalassotherapy, physical therapy, and overall physical wellness care.
The difference between a thalassotherapy spa and a standard spa hotel
The main difference lies in the raw materials and the technical team. A conventional spa hotel typically uses chlorine-treated “tap water” focused on entertainment or superficial relaxation.
In contrast, a thalassotherapy center features specialized intake pipes drawing water directly from the sea, operates under specific health permits, and employs a medical team and physical therapists who guide sessions to treat genuine conditions such as rheumatism, back issues, chronic stress, or fluid retention.
A sanctuary dedicated to personal care and longevity
Today, the facilities in Benicàssim go far beyond the water circuit. Its program includes seawater shower massages, seaweed wraps, natural beauty treatments, and personalized nutrition plans based on locally sourced ingredients. It has become a highly sought-after retreat for those looking to disconnect for a few days or follow a comprehensive health program.

The privilege of living minutes from one of Europe’s top thalassotherapy centers
Having the chance to slip away for a warm saltwater soak on a Tuesday afternoon is one of those small details that transforms your lifestyle. You don’t need to plan long vacations or travel far to care for your body because you can do it right next to home—and that is a true luxury.
Benicàssim offers that balance between tranquility and proximity to top-tier amenities like this. If you want to live in the area, Azure El Poblado elevates this duality to the next level. It is an exceptionally peaceful residential complex away from the crowds, yet located just steps from Benicàssim and Oropesa del Mar, and seamlessly connected to Valencia and Castellón. Living at Azure El Poblado means enjoying the ultimate luxury: having everything, including an internationally recognized thalassotherapy spa, right on your doorstep.
