Denver Zoo has been a City Park fixture since a single donated black bear cub arrived in 1896 — and in 2026 the zoo is marking its 130th anniversary. Today it’s an 80-acre campus, home to more than 2,500 animals across roughly 450 species, and one of the most historically significant zoos in the country thanks to its groundbreaking 1918 Bear Mountain exhibit.
Whether you’re trying to nail down hours and ticket prices, figure out parking, or just want to know what to see first, this guide covers the practical details alongside the history that makes Denver Zoo more than just another animal park.
Quick Answer
Denver Zoo is open daily, typically 9 a.m. to 4 p.m., and is closed on Thanksgiving and Christmas. Non-members need a timed-entry ticket booked online in advance; parking is free in the adjacent lots and the four-level garage off 23rd Avenue. Don’t miss Bear Mountain, Predator Ridge, Tropical Discovery, Toyota Elephant Passage, and the new Down Under Australian habitat.
Denver Zoo Hours, Tickets & Prices
Denver Zoo operates year-round from 9 a.m. to 4 p.m., with members getting early entry from 8–9 a.m. during the Memorial Day–to–Labor Day stretch. The zoo closes only on Thanksgiving and Christmas Day. Because hours can shift for holidays, special events, or weather, always confirm the current schedule on the official Denver Zoo hours and admission page before you go.
Admission runs on a timed-entry system: everyone (aside from members and children under 2) needs a reservation for a specific arrival window, released about 10 days ahead and non-refundable. As of this year, general admission pricing tiers are roughly $27 for adults (16–64), $24 for seniors (65+), and $19 for youth (3–15), with children under 2 free with a complimentary ticket. Zoo Lights and other special events are ticketed separately from daytime general admission. Because prices are adjusted periodically, treat these as a planning baseline and check the official site above for the exact current rates before booking.
Parking at Denver Zoo
Parking is free for all guests, available in the surface lots adjacent to the zoo or in the four-level parking garage along 23rd Avenue. Because City Park hosts other attractions and events, the zoo encourages arriving 10–15 minutes before opening for the best spot, and offers alternatives like biking, walking, or public transit for anyone hoping to skip the lot altogether.
Best Time to Visit
Late spring and early fall tend to offer the most comfortable weather without peak summer crowds, and spring is also when zoo babies — giraffes, eastern bongos, kudus, and wallabies among them — are most likely to make an appearance. Tuesday through Thursday are generally the quietest days of the week.
Arriving right at opening (or in the early afternoon) helps you beat the mid-morning-to-noon rush. In hot weather, animals like lions are most active in the cool of early morning or late afternoon, and the zoo periodically opens early during heat waves to give guests a cooler window before the crowds arrive.
Must-See Exhibits & Animals
Bear Mountain, opened in 1918, is the zoo’s most historically important exhibit — widely credited as the first naturalistic zoo enclosure in the U.S., replacing barred cages with a sculpted, moated habitat. Predator Ridge lets lions and hyenas roam a shared African savanna landscape, while Tropical Discovery is an indoor rainforest housing more than 2,000 animals, including Komodo dragons and king cobras.
Toyota Elephant Passage, a $50 million exhibit that opened in 2012, remains one of the zoo’s largest habitats. The newest major addition is Down Under, a $7.8 million, 3-acre Australian habitat that opened in May 2024 with red kangaroos, red-necked wallabies, endangered huon tree kangaroos, and southern cassowaries — including an immersive walkthrough path where guests get close to free-roaming wallabies and kangaroos.
Denver Zoo Lights
Each winter, Denver Zoo transforms into Zoo Lights, a holiday lantern and light display spread across the 80-acre grounds, with highlights around Elephant House, Village Hall, and Tropical Discovery. It’s a separately ticketed event from daytime general admission, and members typically receive a discount on Zoo Lights tickets. Check the official site for current dates, since the event runs on its own seasonal calendar.
Membership & Free Admission Options
Members get unlimited admission year-round with just a photo ID and the zoo’s digital membership card, bypassing the timed-ticket system entirely. For non-members, Denver Zoo offers seven Community Free Days each year through an online lottery, plus a SNAP/EBT program offering $5 admission for up to 10 guests with a reservation. Families with kids enrolled in Denver’s Great Kids Head Start program can also access free admission through the zoo’s partnership program.
A Legacy Built in City Park
Denver Zoo traces its roots to 1896, when a black bear cub was given to the city and housed in City Park, marking the start of what would become a major Rocky Mountain attraction. Over the following century, the zoo expanded steadily, adding exhibits that reflected changing ideas about animal welfare and habitat design, most notably the 1918 Bear Mountain, an early departure from cage-based zoo architecture.
Conservation Focus Today
In 2024, the organization rebranded as the Denver Zoo Conservation Alliance, underscoring its work on wildlife conservation projects across dozens of countries alongside its role as a family attraction in City Park. The rebrand didn’t change the zoo’s day-to-day visitor experience — it’s still commonly called Denver Zoo — but it formalized the institution’s global conservation partnerships as a core part of its mission, not just a side project.
