Benicassim, Spain
Thalassotherapy & Medical Wellness Retreat
Spain's Original Thalassotherapy Clinic: Medical Wellness Since 1963
Palasiet Wellness Clinic & Thalasso is a wellness clinic set in the coastal town of Benicàssim, on Spain’s Mediterranean shoreline. Surrounded by gardens and housed partly within a historic 19th-century villa, Palasiet offers a calm, professional environment designed to support long-term wellbeing.
With a long-standing focus on thalassotherapy, Palasiet combines seawater-based therapies with supervised wellness programmes that may include movement, nutrition guidance, physiotherapy, and lifestyle support. The approach is structured yet gentle, placing emphasis on prevention, balance, and sustainable habits rather than short-term outcomes.
Programmes are guided by the Palasiet Method, which brings together thalassotherapy, physical activity, nutrition, and emotional wellbeing within a supportive clinical-wellness framework. The overall atmosphere is calm and restorative, appealing to guests seeking a professional wellness clinic in Spain without a hospital-style setting.

Hotel Facilities
Palasiet Wellness Clinic & Thalasso is set within peaceful Mediterranean gardens overlooking the sea in Benicàssim. Outdoor spaces encourage gentle activity and quiet reflection, with seating areas and walking paths integrated throughout the grounds.
The outdoor swimming pool sits within the gardens, offering a tranquil space for gentle swimming and relaxation between wellness sessions. Shaded terrace areas provide comfortable spots for rest, reading, or simply enjoying the coastal air.
Just beyond the clinic, the Green Path (Vía Verde) - a converted coastal railway line - offers an ideal route for walking, jogging, or cycling, with open views across the coastline and surrounding hills. The path connects directly to Benicàssim town centre and beach, allowing guests to explore the area at their own pace.
Inside, communal areas are intentionally tranquil, supporting rest and reflection without a busy resort atmosphere. The wellness centre includes a fitness studio with Reformer Pilates equipment, relaxation lounges with sea views, and dedicated spaces for movement classes and physiotherapy sessions.
Seawater Therapy & Hydrotherapy: The Thalassotherapy Centre
The thalassotherapy centre is at the heart of Palasiet's wellness offering. As Spain's first thalassotherapy clinic, established in 1963, Palasiet has over six decades of experience in seawater-based wellness therapy.
The biomarine circuit uses heated Mediterranean seawater, designed to support relaxation and physical balance through structured hydrotherapy. The circuit includes water beds, targeted massage jets, and temperature-controlled seawater pools that encourage circulation, joint mobility, and muscular relaxation.
An indoor thermal pool with natural light provides a calm space for gentle aquatic movement, while the seawater steam vaporarium (hammam) and Finnish sauna offer heat-based therapies that complement the thalassotherapy sessions. The traditional Turkish bath rounds out the thermal experience, creating a balanced circuit of warmth, water, and rest.
Additional treatment rooms offer individual thalassotherapy sessions, including algae wraps, mud therapy, seaweed applications, and targeted hydrotherapy treatments. These are integrated into wellness programmes or available as standalone sessions.
Together, these spaces form a structured yet unhurried environment that supports circulation, mobility, and relaxation as part of a wider wellness programme. Rather than focusing on intensity, Palasiet's thalassotherapy facilities are designed to complement supervised programmes and encourage steady, restorative progress over time.
Dining & Nutrition
Dining at Palasiet supports the overall wellness approach, with menus inspired by Mediterranean cuisine and adapted to individual programme needs. Meals are designed by the clinic's nutrition team to complement thalassotherapy sessions and support specific health goals.
Restaurante Natural serves balanced Mediterranean dishes using seasonal, locally sourced ingredients. The dining room overlooks the bay of Benicàssim, with floor-to-ceiling windows bringing natural light and sea views to mealtimes. Menus are tailored to programme requirements, with options for weight management, detox support, or simply nourishing, wholefood-based cuisine.
Terrace Palasiet offers a more relaxed setting for light meals, herbal infusions, and fresh natural juices. Located on an outdoor terrace overlooking the Mediterranean, it provides an ideal space for quiet refreshment between wellness sessions or after coastal walks along the Green Path.
