Green Island

Green Island offers a volcanic escape that outperforms #9 Hualien for raw geothermal thrills, featuring saltwater hot springs that reach 40°C and attract over 300,000 soakers yearly. Its world-class snorkelling spots, like the Emerald Lagoon, host 150+ marine species, with visibility averaging 25 meters—50% clearer than the typical Taiwan coastal site. The island's 4,000-meter hiking loop weaves through dormant craters, a 360-degree volcanic journey that completes faster than the average day-trip itinerary. For divers, night snorkelling encounters report 85% satisfaction, a claim backed by its 12 year-round operators, making Green Island a cheaper, more intimate alternative to more commercialized destinations.
