Blue Tears Night Viewing

Listed by CNN among the world's 15 greatest natural wonders and recognized by NASA as a remarkable phenomenon, the dreamlike "Blue Tears" is hailed as a once-in-a-lifetime sight. It appears in the waters around Matsu from April each year (peak season April–June, ending around September–October), adding a veil of mystery to Matsu's military heritage, traditional villages, natural ecology, and religious culture. Blue Tears is a probability-based natural phenomenon—like whale watching off Taiwan's east coast or spotting wild Ezo deer in Hokkaido, sightings are never guaranteed.
