The island is well preserved with consulates, churches, mansions, foreign firms, schools, hospitals, etc. established by Britain, the United States, etc. 13 countries. The buildings are in various forms, including cornices with southern Fujian style, gossip buildings called "Little White House", majestic and towering Catholic churches, European buildings with red tiles and large slopes, and various villas with a combination of Chinese and Western styles, which still exist today.

The houses and streets in Gulangyu Island are built on the mountain, and the buildings are staggered, high and low. The shadows in the deep alleys are graceful, the vines on the walls are climbing, and the bonsai on the windowsill is competing for each other. Walking in them is like shuttling through the alleys staggered in time and space. The main tourist attractions on the island are Sunlight Rock, Luzhuang Garden, Haoyue Garden, Underwater World, Yuyuan Garden, Huandao Road, Gulangyi, and natural bathing beach. Sunlight Rock, commonly known as "Huangyan", is located at the top of Longtou Mountain in the south-central part of Gulangyu Island, with an altitude of 92.68 meters, which is the highest peak in Gulangyu Island. There is a circular platform on the top of the rock, standing on the peak, overlooking the railing, and the scenery of Gulangyu Island is panoramic-the coast is winding and the rocks are undulating; Green trees, red tiles and golden sands meet; Bays, reefs, cliffs and hills set each other off; The huge ship array and seagulls soar ... form a bright and dazzling picture of the island. Being there, thinking about the past and caring about the present will make people feel deeply moved. After swimming in Sunlight Rock, we walked down the mountain and walked about 500 meters along the winding alley. Suddenly, we felt that the world was different. The natural bathing beach in front of us was an intoxicating beautiful scenery: the sky was far away, the sea was the same color, the white waves were flying with gulls, the sea breeze was refreshing, the sands, green trees, blue sea and colorful clouds reflected each other in the beautiful sunset, and people who were paddling and swimming in the bay cheered.

On the hill near the bathing beach is the world-famous Piano Museum, and the island is also known as the piano island and the hometown of music. Gulangyu people were influenced by western church music earlier, forming a tradition of loving music. There are more than 600 pianos on the island, and the per capita piano ownership density ranks first in the country, with more than 100 musical families. Years and wind and rain have given Gulangyu a profound connotation of the intersection of Chinese and western cultures and the blending of natural landscape and human landscape, and it has become a valuable tourism resource with unique characteristics. The night view of Gulangyu Island is like a big flowerpot with dazzling flowers, which is in harmony with the neon lights and color spotlights in the bustling downtown area of Xiamen across the river. The three-dimensional space of the island, the sea and the sky is integrated and becomes more brilliant and charming, just like a fairyland on earth.
