Neat place with lots of cool and interesting little animals.

🏆 Family Action Verdict

Best for families with kids ages 4 and up who are fascinated by unusual animals. The naked mole rat exhibit alone generates reliable excitement from children. The indoor setting makes it a strong wet-weather option within the zoo.
