Fremont Bridge Mouse Door 🐭 Hidden on the Fremont Bridge is a tiny mouse-sized door that has become a delightful surprise for observant visitors. It's easy to walk right past, but if you take a moment to look around, you'll discover a miniature world that inspires people to leave tiny gifts and decorations. This location was recommended by a Found Washington community member, and we added a tiny plant during our visit. 👀 Please enjoy it respectfully and leave it just as magical for the next visitor.
