About OMSI

https://www.omsi.edu

Oregon is one of the most beautiful states in the U.S. If you live there, or even if you’re passing through, you’ll want to be sure you take the time to visit Portland. The views will take your breath away and there’s just so much to do there. OMSI is one option if you’re looking for something to do while you’re in Portland, and this is an experience that’s very different from anything you’ve ever done before. OMSI is a science, technology and learning facility that has something for everyone in your family. You’ll love the exhibits that offer science experiences in ways that are engaging and fun for your kids, and you’ll have a blast with them too. Check out the theater to find out what’s showing on the day you arrive, and be sure to look into all of the great events that are happening at OMSI every day.
