Suggested interest ages

Suggested interests: ages 0–17

Editorial age guidance

Editorial suggestion: ages 0–17. Animal viewing and open-air exploration can suit a broad family age range, and the official visitor information describes family amenities; this is an interest suggestion, not an admission or ride rule. Babies and toddlers can attend, while attraction suitability should be checked individually.

Visitor planning notes

The Zoo states it is open daily year-round but is closed Jan. 1 and Dec. 25; hours vary, so confirm hours and attraction operations for the visit date. Stingrays at Caribbean Cove and the Sea Lion Show are not open from late fall through early spring, and Dinoroarus is seasonal. Stroller rentals are first-come, first-served and not guaranteed. Entry security may search strollers and bags. The Zoo is cashless; cash-to-card kiosks are available. Children under 14 must remain with an adult.
