We visited the O Museum to explore the rooms and discover the hidden doors. We spent half the day searching for hidden doors, retracing our steps, and shopping for interesting items. We found 24 doors and were done for the day! We will return to search again. This is an amazing place to explore, enjoy, and relish what the O Museum has to offer those who enter. This is a hidden gem of Washington DC. You can uncover the hidden doors if you are willing to search and keep an open mind!

Last rainy day of spring break brought us this gem and once we (mom and three kids 15, 12 and 10) found our first door (we found 4!), we were hooked and will definitely be back to explore more!!
