Wisconsin punches well above its weight on free museums. Madison alone has a remarkable cluster of always-free institutions — the Chazen Museum of Art and the Madison Museum of Contemporary Art (MMoCA) are both free, as are the University of Wisconsin Geology Museum and the Wisconsin Veterans Museum on the Capitol Square. Out in the state, the Leigh Yawkey Woodson Art Museum in Wausau (famous for its 'Birds in Art' show), the John Michael Kohler Arts Center and its Art Preserve in Sheboygan, and Racine's Wustum Museum all charge nothing, ever. On top of that deep free bench, Wisconsin's two ticketed giants in Milwaukee both run generous free windows: the Milwaukee Art Museum is pay-what-you-wish every Thursday from 4 to 8 p.m., and the Milwaukee Public Museum is free to all on the first Thursday of every month. Every entry below was checked against the museum's own admission page.
A few more ways in: the Milwaukee Public Museum's free first Thursdays are branded 'Kohl's Thank You Thursdays' — admission is free, but reserve online up to a week ahead, since walk-ups aren't guaranteed — and Milwaukee County residents get $2 off MPM admission any day. EBT cardholders get $1–3 admission widely through the Museums for All program, and for one more cheap art fix, Milwaukee's Grohmann Museum of industrial art is just $5.

Milwaukee Art Museum
Regularly $27 adultsThe Milwaukee Art Museum — home to Santiago Calatrava's wing-flapping Quadracci Pavilion on the lakefront — is pay-what-you-wish every Thursday from 4 to 8 p.m., the cheapest way for adults to see the collection (regular admission is $27). Kids 12 and under are free every day thanks to an anonymous donor, and Wisconsin K–12 teachers are free with school ID. Even without going in, watching the Burke Brise Soleil 'wings' open and close is free from the lakefront lawn. (The one exception: PWWW is paused during Art in Bloom each spring.)

Regularly $25 adultsMilwaukee's beloved natural-history museum — with its walk-through 'Streets of Old Milwaukee' and rainforest dioramas — is free to all visitors on the first Thursday of every month (10 a.m.–5 p.m.) under its 'Kohl's Thank You Thursdays' program, which covers the permanent exhibits. Admission is free but you should reserve online up to a week ahead, since walk-up tickets aren't guaranteed. Regular admission is $25 (and Milwaukee County residents get $2 off any day). This is the farewell stretch for the longtime downtown building before the museum moves to its new home, so it's a good year to go.

Olbrich Botanical Gardens
Regularly $6 (Bolz Conservatory)Olbrich's 16 acres of outdoor gardens on Madison's east side — including the gold-leafed Thai Pavilion — are free to walk every day of the year. The indoor Bolz Conservatory, a tropical glass dome full of orchids and birds, normally costs just $6 ($3 for kids 6–12, free under 5), but it's free for everyone on Wednesday and Saturday mornings from 10 a.m. to noon, and free anytime for Museums for All (EBT) cardholders. Donations are gratefully accepted.

Racine Art Museum (RAM)
Regularly $10 adultsRAM, in downtown Racine, holds the largest collection of contemporary craft in the country, and admission is free on the first Friday of every month (sponsored by the Osborne and Scekic Family Foundation). General admission is otherwise just $10, with up to three kids 12 and under free per adult. And RAM's sister site two miles away — the Charles A. Wustum Museum of Fine Arts — is free every day of the year. Both are open Wednesday–Saturday, 10 a.m.–4 p.m.
