Poseidon Thermal Gardens (Giardini Poseidon Terme)

 The complex is typically referred to as the largest wellness and thermal park in Ischia, operating on a 6-hectare terraced area, according to official information, featuring 20 pools, as well as separate seawater pools and beach access. 

A visit works well at your own pace. Many start with the classic thermal circuit, then include a seaside break on Citara Beach, and return for a more relaxed, restorative dip in the pools. One of the park's strengths is that it offers more than just swimming pool experiences: it specifically incorporates hydrotherapy elements, such as the alternating temperature Kneipp programme, the Japanese-style foot bath, and the natural steam cave experience, which many consider the essence of the “Poseidon experience.” For those seeking a deeper wellness programme, the on-site health and treatment centre (offering massages and therapeutic services) completes the day. 

From a tourist perspective, Poseidon Thermal Gardens is best enjoyed when you dedicate a full day to it, rather than treating it as a quick stop. The season is highly dependent on weather and opening hours, so it’s worth checking the current period and daily schedule before your visit. According to official information, the park’s pools are regularly emptied and cleaned, and the calm, relaxation-focused environment is safeguarded by house rules; for instance, to maintain pool cleanliness, the use of swim caps is requested in several areas. 

Sustainability efforts at Poseidon are particularly tangible and go beyond mere communication. According to the park’s own introduction, it strives for an environmentally conscious, “plastic-free” operation, including the use of glass to replace plastic, waste sorting and reduction. External local “green” summaries also highlight that single-use plastics have been significantly reduced in catering, and efforts are made to recycle and reuse packaging. In garden maintenance, natural/organic solutions and composting are applied, alongside the use of locally crafted, natural-material (e.g., raffia) sunbathing equipment.
