6: Oregon Museum of Science and Industry
Fill your minds with the wonders as you enjoy your Portland vacation at the Oregon Museum of Science and Industry. It lures people of all ages with the giant screen theater, the planetarium, and the USS Blueback, which is a retired Navy sub. The Science Playground is one of the Portland activities that are designed for kids, and adults can bask at the Theory Cafe, which takes museum food to the highest levels.
