The National Museum of Automobile was founded in 1933, becoming one of the first automotive museums in the world. It hosts a very rare and fine collection of cars from Italy, France, Great Britain, Germany, the Netherlands, Spain, the US and Poland. The exposition displays the brands of the past and present dating back to the middle of the 19th century, reaching approximately 200 models.

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.

The Palatine Gates date back to ancient Roman times, when they provided access for travellers coming from the north. Today, the gates are part of the archaeological park located in the city centre, together with other ancient ruins, such as the remains of a Roman theatre.
