Bay Beach Wildlife Sanctuary

Bay Beach Wildlife Sanctuary is one of Wisconsin's best-kept family secrets: a 700-acre wildlife refuge on the shores of Green Bay that charges absolutely nothing to get in. Run by the City of Green Bay, the sanctuary rehabilitates injured and orphaned native Wisconsin wildlife — and the animals that can't be released live in naturalistic enclosures spread across the grounds.

What you'll see on any given visit: bald eagles with 6-foot wingspans perching close enough to study, timber wolves pacing their habitat, white-tailed deer grazing, great horned owls, red foxes, river otters, sandhill cranes, and dozens of other native species. Because these aren't zoo animals bred in captivity — they're rescue animals — the experience feels different. Your kids will hear the actual story of why each animal is there, posted on signs that even early readers can follow.

The grounds are genuinely spacious, so plan on 2-3 hours to see everything without rushing. Strollers handle the main paved paths well. The indoor nature center building has exhibits and restrooms, and staff naturalists are on hand to answer questions. There's no admission gate, no tickets to buy, and no upsell — just walk in.

For parents, the 4. 7-star rating with nearly 3,000 reviews tells the story: this place consistently delivers. The combination of free admission, genuine wildlife encounters, and low-stress logistics makes it an easy yes on any weekend.

It pairs beautifully with Bay Beach Amusement Park right next door, which has carnival rides for 25 cents each — so a full family day including lunch and rides can come in under $20 total.

Best seasons are spring through fall, but the sanctuary stays open year-round. On a cold winter morning, the wolves especially become more active and visible — and you'll have the place nearly to yourself.
