Every year when April and May arrive, the starry fireflies begin their abundant flight season, marking the prime time for firefly watching across Taiwan. In Carefree Valley, located in Sanyi Township, Miaoli County, there lies a hidden gem for firefly enthusiasts. The firefly-watching area is planted with ground cover of moneywort and mint. Due to the bluish hue that moneywort takes on under low light, combined with the yellow-green glow of the fireflies, the entire grassy expanse transforms into a sparkling blue sea of lights — hence earning the nickname “Sanyi Blue Tears.” The interplay of yellow-green and blue lights weaves a breathtakingly magical scene, attracting numerous visitors and photography enthusiasts to this pilgrimage site. Carefree Valley is situated within the West Lake Resort, covering a vast area filled with lush greenery and rich ecological resources and environment, making it an ideal holiday destination for those looking to connect with nature.
