If you saw the movie Frida, the studio and home of Diego Rivera and Frida Kahlo is a must stop on your visit to Mexico City — some of the scenes were filmed here. The complex of buildings is a great example of functional architecture, with its abundance of soft light and free flowing creative atmosphere. The houses are linked with an elevated walkway, representing the separate yet linked lives the two great artists lived. Check for temporary visits before going! Some areas of the house might be closed if there is no exhibit.

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.

After its opening in 1898, the Ferry Building became the transportation focal point. At its peak, as many as 50,000 people a day commuted by ferry. An elegant two-story public area with repeating interior arches and overhead skylights, the Ferry Building is a great place to be whether you're looking to dine, shop for fresh and local produce, or just look around. You'll find lots of delicious seafood restaurants along the back of the building where you can overlook the harbor. Don't miss Hog Island Oysters and Gott's Roadside. The farmers market takes place every Tuesday, Thursday, and Saturday from 10am to 2pm. As a city committed to environmental sustainability, every vendor here has adopted a sustainable mission, and therefore, sells mostly organic products. Speaking of eco-friendly practices, the Ferry Building has been working closely with the transit authority to support the revitalization of the waterfront and the wildlife that resides in the bay.
