In-depth insights and expert knowledge
The Geology of Guishan Island
The most striking geological feature is the 'Milk Sea', a unique phenomenon caused by underwater volcanic vents releasing minerals. This creates a surreal, milky blue or turquoise color in the surrounding waters, especially visible when the currents stir up the seabed. The island's volcanic activity also contributes to hot springs and fumaroles.
Historically, residents lived on the island until the mid-1970s when they were relocated to the mainland due to structural damage to homes caused by volcanic activity and seismic events. Today, the island is primarily a tourist destination, carefully managed to preserve its natural and geological significance.
Experiencing the Milk Sea
While swimming directly in the Milk Sea is generally not allowed due to safety concerns related to the volcanic vents, many boat tours will circle the area, allowing passengers to get close and take stunning photographs. Some tours might offer opportunities for swimming in designated, safer areas nearby. The visual impact of the Milk Sea against the backdrop of Guishan Island and the Pacific Ocean is truly unforgettable.
To best appreciate the Milk Sea, aim for a tour during daylight hours when the colors are most vivid. The clarity of the water and the intensity of the sunlight play a significant role in how the Milk Sea appears. It’s a photographer's dream and a unique natural spectacle that sets Guishan Island apart.
Hiking and Island Exploration
Beyond the main trail, exploring the island allows you to appreciate its unique volcanic terrain and sparse vegetation. The island was once inhabited, and you can still see signs of its former community. The feeling of being on a remote, geologically active island is palpable, offering a sense of adventure and discovery.
It's crucial to wear appropriate footwear for the hike, as the steps can be steep and uneven. Staying hydrated is also important, especially during warmer months. The effort is well worth the incredible vistas and the unique experience of walking on Taiwan's only active volcanic island.
