This is not just a park, but a representative scenic area covers more than 120 hectares. The park contains rivers, mountains, Chinese gardens, traditional architectures and an underground cave. The Seven Star Cave in the park is a fantastic karst cave with a large number of stalagmites and stalactites, which transform the cave into a surreal place. If you can only visit one place in Guilin, this should be it.

Experience firsthand why Portland is known as the "City of Roses" by visiting its Rose Test Garden, the oldest official rose garden in the U.S. Established during World War I, the garden was originally created as a refuge for roses threatened by bombings and potential extinction. Not only did the roses survive, but they have continued to thrive and bloom in Portland. The garden is open to visitors from April through October, with the peak bloom occurring in June.

Portland is home to the nation's largest wooded urban park—Forest Park. A short hike in, and you'll find it hard to believe that civilization is just steps away. With 70 miles of trails winding through the forest and offering views of the Willamette River, you'll often have nature all to yourself. However, you're also likely to run into locals jogging or walking their dogs—expect to be greeted with a friendly "hello." If you have the time, hike up to Pittock Mansion, a stunning French Renaissance-style château that once belonged to Henry Pittock, a prominent publisher and businessman. Today, the mansion serves as a historic house museum open to visitors, offering panoramic views of the city. Another popular destination within Forest Park is the so-called "Witch's Castle"—the moss-covered ruins of an abandoned stone house. Despite its eerie name, there’s no record of witchcraft here. However, legend has it that its original inhabitant was the first person in Oregon to be sentenced to execution for murder in 1859.
