Giardini Poseidon

Twenty thermal pools among Mediterranean gardens overlooking the sea at Citara: the island's most scenic thermal park.

Overview

Giardini Poseidon occupies an entire natural bay at Citara, on Ischia's western side. Twenty pools at graduated temperatures, from 38°C to 27°C, are set among terraces of Mediterranean vegetation that descend to a private fine-sand beach. It's the island's most complete thermal park: there's a heated seawater pool, a natural sauna carved into the rock, an aromatic Turkish bath and Kneipp paths for circulation.

Why visit it

It's the right choice for those who want a whole day of wellness without moving around: pools, sea, gardens and dining are all in the same space, arranged on terraces that let you alternate thermal relaxation and beach time at your own pace.

Practical tips

  1. Arrive in late morning to avoid the early-afternoon peak
  2. Bring non-slip sandals: the walkways between the terraces are stone
  3. On-site parking is limited, an organised transfer is recommended
  4. April-June and September offer the best conditions, with fewer crowds
