Zhaori Hot Spring essentials

Address: Green Island, Taitung County, Taiwan

Zhaori Hot Spring sits on Green Island, a small coral island off Taiwan’s east coast and part of Taitung County. During the period of Japanese rule the spring was known as Asahi Hot Spring, a name that reflects its reputation for ocean sunrises. The site occupies a rocky coastal spot where heated seawater emerges and has been arranged into bathing pools and terraces.

Geologically the spring is notable because its water is saltwater drawn from the sea and heated underground by volcanic activity; it is one of only a few saltwater hot springs in the world. Reported source temperatures are high, so pools have been terraced and channelled to give bathers cooler options. Architecturally the site comprises several open-air pools, a spa pool and a series of terrace-like basins that step down toward the shoreline.

Visiting feels very coastal and exposed rather than a sheltered, forested hot-spring resort: you soak with sea air, waves and often strong sunlight. Facilities on the small island are modest, so many travellers combine a visit with other island activities such as snorkeling or a short coastal walk. Check local information for access rules and any seasonal closures before you go.

  • Saltwater pools: The hot spring pools use seawater heated by the island’s geology, giving a distinct saline feel compared with freshwater springs.
  • Terrace pools: A series of terrace-like basins step down toward the sea, offering different soaking spots and views.
  • Open-air ocean views: Pools are open to the sky and face the ocean, making sunrise and sunset soaks especially atmospheric.
  • Coastal scenery and reefs: The rocky shore and nearby coral reefs create a marine backdrop and combine well with snorkeling trips around the island.
