The Children's Discovery Museum of San Jose is consistently rated one of the best children's museums in the United States. The building — a striking purple structure by Mexican architect Ricardo Legorreta, near the convention centre south of downtown — houses two floors of interactive exhibits where children explore everything from water dynamics to world cultures.
The Waterworks exhibit, a large outdoor water play area, is particularly popular. The museum is genuinely creative rather than simply educational — the exhibits are designed to spark imaginative play, not just demonstrate concepts. It is an excellent option for families with young children, and adults accompanying kids will find enough of interest to stay engaged.
