Foresta Wellness Boutique Gym & Spa

Foresta Wellness Boutique Gym & Spa is an adults-only wellness venue beside the Miramón woodland in San Sebastián. Its atmosphere is quiet and nature-led, with the experience centred on slowing down, restoring balance and spending time away from everyday noise. Large views towards the surrounding parkland accompany the spa’s relaxation areas and thermal spaces.

The water circuit forms the core of the visit. It combines a cool contrast pool at 15°C, a 34°C hydrotherapy pool with several massage features and a 38°C magnesium bath. The mineral bath uses Epsom salts alongside hydromassage, creating a warm, restorative stage within the circuit. The sequence is designed around changing temperatures and sensations, with an emphasis on easing physical tension and encouraging relaxation.

Foresta’s thermal area includes three distinct experiences: a traditional Finnish sauna, a steam room and an infrared sauna with full-spectrum LED light. The steam room incorporates eucalyptus and menthol aromatherapy. A separate rest area provides a quieter place to pause and rehydrate, with views towards the natural surroundings and a purified, hydrogenated water fountain.

Treatments extend the spa beyond the water and heat areas. The body menu includes massage and aromatherapy therapies intended to release physical and mental tension, with different techniques and levels of intensity. Ritual treatments combine botanical oils and energy-based therapies, while the facial range focuses on botanical skincare and techniques influenced by traditional practices. The treatment style is closely connected to nature, plant-based cosmetics and sensory relaxation.

The venue suits adults seeking a structured spa circuit, a thermal retreat or a treatment-focused break in a forest setting. It also works for guests staying at the adjoining hotel who want to add a dedicated wellness element to their time in the area. The setting in Miramón gives Foresta a calmer character than a city-centre spa, while its location keeps it within San Sebastián’s wider urban area. Advance planning is sensible for both spa access and treatments, particularly when a visit depends on a particular time or therapy.
