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.

This sanctuary gives you the opportunity to touch and hold koalas in the world’s largest koala enclosure. The site is easily accessible by bus from the CBD, or via Miramar Cruises who make daily trips from the South Bank’s Cultural Centre pontoon at 10 am.

You will find the Big Buddha on Lantau Island which is the largest island in Hong Kong. Big Buddha is the world's largest seated outdoor bronze Buddha statue, which is more than 34 metres high. After the visit, head to the monastery nearby where you can eat a vegetarian lunch with the monks.
