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.

A short trip out of Pula takes you to the acclaimed Brijuni National Park. This archipelago of islands has long been noted for its outstanding natural beauty and are edged with turquoise waters rich in sea life. A favourite haunt of visiting heads of state and the summer residence of Marshal Tito, from 1949 until his death in 1980, the islands can be reached by boat from Fažana, a village 5km from Pula, which is easily accessible by bus.

This ancient religious edifice is formed of an eclectic mix of architectural styles, reflecting the many changes it has undergone in its lengthy history. You can still see some of the 4th century remains on the outside of the church, from a time when the area was used as a refuge by Christians in times of persecution.
