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 museum of oddities is a temple of all things weird, bizarre, and — at times — gross and creepy. From an alien autopsy table and (somewhat disturbing) crime scene recreations to treats served at the on-site café (dessert with crickets and scorpion bits, anyone?), the Peculiarium is a bloody good time if you're not too squeamish (or underage).

Overlooking the impressive Alhambra palace lies the lovely Generalife Garden. With its bright flowerbeds and picturesque fountains, its higher and lower gardens are the ideal spot for an evening stroll. You don’t want to miss this Andalusian scenery with great architecture in a floral setting on your holiday pictures.
