Rochester, NY

Three floors of hands-on science plus the Strasenburgh Planetarium next door, which runs star shows and full-dome films on a big tilted dome. Exhibits cover electricity, motion, regional geology and the Seneca and Haudenosaunee history of the area. Younger kids get the How Things Work and Adventure Zone areas where nearly everything can be operated. The planetarium is a separate ticket but is the thing kids remember. A short drive from the Strong, so a Rochester weekend can be built entirely indoors in February.

The best indoor family destination in upstate New York, full stop, and worth a drive from anywhere in the state. It is enormous: a walk-through Sesame Street set, a full arcade with classic cabinets, a butterfly garden, a working carousel, a Berenstain Bears house and the National Toy Hall of Fame. The 2023 expansion added a whole neighbourhood of new play worlds and an indoor skyline bridge. Older kids and teens stay engaged through the video game history halls while toddlers have their own zones. Budget a full day and expect to still miss things.
