Tips for Visiting Zoos in the U.S.
Buy Tickets in Advance
Many zoos offer discounted admission when you purchase tickets online ahead of your visit. Not only can you save money, but you’ll also skip the long ticket lines at the entrance—giving you more time to explore. Some zoos even have limited-capacity days or special experiences that require advance booking, so planning ahead ensures you don’t miss out.
Visit Early or on Weekdays
If you want to see animals at their most active, plan to arrive right when the zoo opens. Mornings tend to be cooler, and many species are more playful before the midday heat sets in. Weekdays—especially Tuesday through Thursday—are generally less crowded than weekends, giving you more room to explore and better photo opportunities without the hustle and bustle.
Pack Essentials
A day at the zoo often means several hours of walking outdoors, so come prepared. Bring a hat, sunglasses, and sunscreen to protect yourself from the sun, along with a refillable water bottle to stay hydrated. Some zoos allow you to bring small coolers or snacks, which can be a budget-friendly way to keep everyone fueled without relying solely on concession stands.
Check Special Events
Before your visit, look at the zoo’s calendar for special events. Many host unique experiences such as nighttime safaris, seasonal festivals, animal feeding sessions, or “keeper talks” where you can learn fascinating facts straight from the experts. These extras can turn a regular zoo visit into a memorable adventure and provide great educational moments for kids and adults alike.
