Think a children's museum, only a little bit smarter. This family-oriented hotspot is full of interactive and educational exhibits that cover all topics that its visitors might find interested. For playing, there is a ballroom, a playroom, sandpit, puzzle areas, plus an under-six area. This museum, the state of Oregon's flagship museum, also includes a tour of the USS Blueback submarine, a motion simulator, planetarium, and an IMAX theater. Plus, it wouldn't be a true museum with a cafe and gift shop. Visitors to this museum are pleased with its spacious areas and care to keep kids interested while meeting them on their level. It's a great family activity.
