Dagushan, also known as the Spring Rain Azalea, is located on the eastern shore at the southern end of Lake Jingpohu Lake and is the largest island in the lake. It stands at an elevation of 415 meters and covers an area of 10,000 square meters. The island is densely shaded by mixed coniferous and broad-leaved forests, with thriving flowers and plants beneath the trees. Every spring when flowers bloom, Dagushan showcases its lush and picturesque scenery—verdant woods, lush grass, and a constant fragrance of blossoms—earning it the nickname "Flower Mountain." Since visitors pass by on boats without setting foot on the island, its flora remains undisturbed, preserving its pristine natural state with 100% vegetation coverage.
