Wyoming is one of the easiest states in the country for a museum trip on a budget, because so many of its best museums simply don't charge admission. The University of Wyoming campus in Laramie alone offers a free art museum, geological museum, and the American Heritage Center, while the Wyoming State Museum in Cheyenne — a block from the State Capitol — is free for everyone, every day, including all of its family programs. Casper adds another cluster of always-free stops, from the BLM's National Historic Trails Interpretive Center to the Tate Geological Museum and its full-size dinosaur casts.
True 'free day' programs at the paid museums are thinner here, but the two best are worth planning around. In Jackson, the National Museum of Wildlife Art (regularly $18) waives admission for area locals on the first Sunday of every month, year-round. And in Cody, the Buffalo Bill Center of the West — the region's largest museum at $23 — admits all Park County, Wyoming youth, from toddlers through high schoolers, plus one accompanying adult per group, completely free all year thanks to a family endowment. Many Wyoming museums also offer reduced 'Museums for All' admission with a SNAP/EBT card, and several take part in Blue Star Museums for active-duty military families in summer.
