About Palasiet Wellness Clinic and Thalasso
Palasiet Wellness Clinic & Thalasso is a thalassotherapy and wellness retreat in Benicàssim, on Spain's Mediterranean coast between Valencia and Barcelona. Established in 1963 as Spain's first thalassotherapy clinic, it has been drawing on the therapeutic properties of Mediterranean seawater for over 60 years — longer than almost any other centre in Europe. The property is housed partly within a historic 19th-century villa, surrounded by gardens with direct access to the coast.
Programmes are guided by the Palasiet Method, which brings together thalassotherapy, physical activity, specialist medical treatments, nutrition and emotional wellbeing into a coordinated plan shaped around each guest's individual assessment. Every stay begins with a medical consultation, from which a personalised programme is built — whether the focus is detox, weight management, stress recovery, longevity or a general thalassotherapy programme.

Who It's For
Palasiet Wellness Clinic & Thalasso suits guests looking for a medically supervised thalassotherapy and wellness retreat in Spain, where seawater therapy is central to every programme. With over 60 years of clinical experience and a coastal setting in Benicàssim, it's particularly suited to:
01
Those seeking Spain's original thalassotherapy clinic
Seawater drawn directly from the Mediterranean, heated to 35-36°C and used across the biomarine circuit and treatment rooms — under medical supervision since 1963.
02
Guests wanting a professionally guided wellness programme
Every stay begins with an individual medical assessment — doctors, physiotherapists and nutritionists working together around the five-pillar Palasiet Method.
03
Those focused on specific health goals
Programmes covering detox, weight management, stress recovery, longevity, menopause and physical rehabilitation — each personalised from the first consultation.
04
Guests who value a coastal Mediterranean setting
50 metres from the sea, Mediterranean woodland gardens, a beach below and wooded hills behind — the Vía Verde coastal trail running directly past the clinic.
The Palasiet Method
The Palasiet Method is the framework behind every programme at the clinic, built on five pillars that work together: thalassotherapy, physical activity, specialist medical treatments, nutrition and emotional wellbeing. In practice this means seawater therapy, nutrition, physical training and any additional medical or therapeutic support are designed as a single coordinated plan — not a menu of separate services.
Every stay begins with an individual medical assessment. What comes back shapes the programme — the treatments prescribed, the nutrition plan, the physical activity level and any specialist interventions — with the team adjusting as the stay progresses.
Hotel Facilities
Palasiet sits in gardens and Mediterranean woodland above the bay, with seating areas and walking paths through the grounds and views out to the sea from most of them. The outdoor pool is set within the gardens with a sun terrace and loungers alongside, and shaded terraces provide spots for reading and sitting out of the heat. Indoors there is a lounge and tea bar, with relaxation lounges looking over the water.
The Vía Verde runs just beyond the property — a converted coastal railway line now used for walking, jogging and cycling, with open views along the coastline and the hills behind. It connects to Benicàssim town centre and the beach, which is 50 metres away.
Wellness Facilities
The Thalasso Clinic covers more than 2,700sqm. Seawater is drawn directly from the Mediterranean, treated and heated to between 35 and 36°C. The biomarine circuit is built around that water — a thermal pool, water beds and seats, cervical and lumbar jets and several jacuzzis, alongside large heated seawater pools, a phlebitic circuit, hydromassage baths and marine bathing areas. A Finnish sauna, seawater steam vaporarium and Turkish bath complete the thermal circuit.
Individual thalassotherapy sessions include algae wraps, mud therapy and seaweed applications, available as part of a programme or booked independently. Treatment areas cover thalassotherapy, sports physiotherapy and rehabilitation, nutrition, physical training, integrative gynaecology, facial and body aesthetics, hair medicine, massage and oriental techniques, and medical services.
Movement takes place across a large gym, a separate studio for Pilates, yoga, muscle chain stretching and relaxation, and the pools, where aquagym classes run as group sessions. Three Reformer Pilates machines are available at a supplement. The team includes doctors, physiotherapists, nutritionists, personal trainers, psychologists, aesthetics specialists and thermal technicians.
Dining
Restaurante Natural is set within the Mediterranean woodland with views across the bay of Benicàssim. The cooking is Mediterranean, built on local produce and seasonal ingredients, with personalised menus designed by the nutrition and kitchen teams together to follow each guest's programme. Healthy cooking workshops run alongside, covering the principles behind a seasonal organic diet.
La Terraza de Palasiet serves natural juices, herbal infusions and a short menu of healthy dishes with sea views — a lighter option for meals between sessions or after a walk along the Vía Verde.
Good to Know
Accommodation
Palasiet has 78 traditionally styled rooms, each with a private terrace or balcony overlooking the Mediterranean Sea, the bay of Benicàssim or the surrounding gardens. Interiors use classic Mediterranean styling with natural materials, soft lighting and calm neutral tones.
Sea-facing rooms benefit from morning light and open coastal views; garden-view rooms offer quiet green vistas and a greater sense of privacy.
Location
Palasiet sits 50 metres from the sea on the bay of Benicàssim, on the Costa del Azahar, with gardens and Mediterranean woodland around it. The property faces the bay with the beach below and wooded hills rising behind. Benicàssim itself is a quiet seafront town, with the centre a short walk along the coast. The Vía Verde coastal trail runs directly past the clinic, connecting to nearby towns along the shoreline for walking, cycling or morning runs.
Valencia Airport is around 60 minutes by road and Castellón Airport nearer at about 30 minutes. The climate stays mild through the year, making it a practical destination at any season.

Frequently Asked Questions
What is Palasiet Wellness Clinic & Thalasso and what makes it special?
Palasiet is a thalassotherapy and wellness clinic in Spain, established in 1963 as Spain's first thalassotherapy centre on the Mediterranean coast in Benicàssim — on the Costa del Azahar, between Valencia and Barcelona. Seawater is drawn directly from the Mediterranean, treated and heated to 35-36°C, and forms the basis of every programme alongside the five-pillar Palasiet Method, which brings together seawater therapy, nutrition, movement, specialist medical treatments and emotional wellbeing into a single coordinated plan.
What is thalassotherapy and how does it work at Palasiet?
Thalassotherapy draws on the therapeutic properties of seawater to support circulation, mobility, recovery and overall balance. At Palasiet, seawater is piped directly from the Mediterranean and used across the biomarine circuit, hydromassage baths, algae wraps, mud therapy and marine bathing areas — the heated pools and phlebitic circuit particularly effective for circulation, joint mobility and musculoskeletal recovery.
What wellness programmes are available?
Twelve programmes run from 2 to 21 nights — Wellness, Reformer Pilates, Yoga, Get in Shape, Detox, Anti-Stress, Therapeutic Thalassotherapy, Vital Menopause, Longevity and three Weight Loss options. Most programmes begin with an individual medical assessment, from which the team prescribes a personalised plan covering thalassotherapy, nutrition, movement and any specialist medical or physiotherapy support.
What is the Palasiet Method?
The Palasiet Method is the clinical framework behind every programme, built on five pillars — thalassotherapy, physical activity, specialist medical treatments, nutrition and emotional wellbeing — working as a single coordinated plan rather than a menu of separate services. Every stay begins with an individual medical assessment that shapes the programme, with the team adjusting as the stay progresses.
Is Palasiet suitable for solo travellers?
Many guests arrive alone. The calm coastal setting, individual daily programme and attentive medical team suit solo travel well — with the Vía Verde trail, the gardens and the beach providing quiet space between sessions.
When is the best time to visit Palasiet?
Palasiet is open year-round and the Mediterranean climate of the Costa del Azahar suits every season. Spring and autumn offer the most settled conditions for outdoor pool use and walking the Vía Verde. Summer brings warm evenings on the terrace, and winter visits are quiet with the full thalasso facilities available throughout.
How do I get to Palasiet?
Valencia Airport is approximately 60 minutes away by road and Castellón Airport approximately 30 minutes — the more convenient option for direct connections from the UK and Europe. Private transfers can be arranged through The Wellness Holiday Boutique as part of your booking.
