Potawatomi Zoo
South Bend · Pre-K–12 · Email registration form to groupadmission@potawatomizoo.org; payment due 2 weeks ahead, 20 paid minimum
Indiana's oldest zoo offers a published weekday field-trip rate — $7 per student through 8th grade — for groups of 20 or more, less than half the regular gate. A homeschool co-op can easily fill the minimum, and teachers and bus drivers come free. Tigers, snow leopards, red pandas, and an Australian Walkabout fill an easy half-day. The zoo also runs a Fall Homeschool Class Series: four-week themed courses for ages 6–8, 9–12, and a 13–18 'Teen Scientists' track, at $60 per series (about $15 a class, $54 for additional siblings, 10% off for zoo members) with hands-on activities and up-close animal-ambassador encounters.
Regular admission: $16 adult / $14 child 3–14 — Roughly half off the gate for a co-op group of 20+
