Seattle Children’s Museum

Rainy day savior, honestly. This place is built for the under-6 crowd, and it actually delivers — climbing structure, a merry-go-round, a play train, and themed exhibits that keep toddlers genuinely occupied for hours. Everything’s indoors, which in Seattle means you’ll probably end up here more than you planned. It’s clean, the restrooms are right there when you need them, and the whole setup feels like someone actually thought about what little kids want to do rather than what looks good in photos. If you’ve got a 2 or 3 year old who needs to burn energy without you freezing outside, this is a solid go-to.
