Upstate

A mid-size aquarium a short walk from the falls, and the obvious move when the mist and wind make the gorge unbearable with kids. Humboldt penguins, harbour seals and California sea lions get daily feeding and training sessions that are the highlight for most children. There are Great Lakes tanks, a shark and ray touch pool, and a small rainforest area. It takes about ninety minutes which fits neatly into a Niagara day. Combining it with the state park makes a rainy Niagara trip actually work.

Three floors of baseball history in a small upstate village, and a pilgrimage for any kid who plays. The Plaque Gallery with every inducted player is the emotional centre, but the artifact halls are what hold kids: game-worn jerseys, Babe Ruths bat, World Series rings and a locker room exhibit with a stall for every team. A short film in the Grandstand Theater sets it up well for younger kids. Cooperstown itself is walkable with baseball card shops on every corner. Two to three hours inside, more if your kid reads every plaque.

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.
