Philadelphia Zoo is stretching its beloved Boo at the Zoo celebration across nearly the entire fall calendar this year, marking the first time in the event's 20-year history that the Halloween tradition has extended into October at all. The expanded 2026 lineup runs 11 operating days, every Saturday and Sunday from October 3 through November 1, with an added holiday opening on Indigenous Peoples' Day, Monday, October 12.
The longer run means five weekends of fall activities for Philadelphia families, as reported by 6abc Philadelphia. Trick-or-treating, Halloween costume contests, giant animal skeletons, hippos chomping pumpkins, a SEPTA-themed Boo Choo train ride and an apple cider bar are all part of the mix, per the station's report. The zoo has also packed in several brand-new attractions for 2026, according to PhillyVoice, including a six-hole Pumpkin Putt mini-golf course on Impala Lawn, a live DJ dance party with a secret candy station tucked inside the Trick-or-Tree House, and a daily costume parade circling Bird Lake at 1:30 p.m.
Exact Dates and Daily Details
For families mapping out their visit, the Philadelphia Zoo has laid out the full calendar: every Saturday and Sunday from October 3 through November 1, plus the Columbus Day holiday Monday, October 12. Entry to Boo at the Zoo is included with general daytime admission, which typically runs $25 to $30 when reserved in advance. Pennsylvania and Delaware ACCESS cardholders can buy discounted $8 tickets online, though the zoo caps those subsidized tickets at 1,000 per day.
Zoo members get a jump on the crowds with exclusive Member Morning Strolls starting at 8:30 a.m., a full hour before public gates open, on Saturday, October 17, and Sunday, October 25. The zoo is also enforcing strict costume rules for safety: no toy guns or weapons as part of any Halloween getup, and no full-face masks worn by adults during the event.
A New Bear Habitat Sets the Backdrop
This fall's expanded Halloween programming arrives just months after the zoo completed one of its biggest capital projects in over a decade. The $25 million Francis J. Carey Bear Country exhibit opened in June 2026, expanding bear habitats by 60% and adding an overhead Zoo360 mesh trail that lets sloth and Andean bears roam above visitors' heads, according to Billy Penn.
Visitors climbing the zoo's 10-story Pherris Wheel during Boo at the Zoo will also get an elevated view of the grounds' 1,500 trees, which typically hit peak autumn color around mid-October, PhillyVoice notes. The timing lines up the expanded Halloween event with Philadelphia's fall foliage season, giving out-of-towners and locals alike another reason to visit West Philadelphia's Centennial District this month.
America's First Zoo, Still Drawing Crowds
The Philadelphia Zoo carries historical weight beyond its seasonal programming. It was chartered by the Commonwealth of Pennsylvania on March 21, 1859, making it America's first zoo by charter, though its public opening was delayed 15 years, until July 1, 1874, because of the Civil War, according to ThrillZing. Today the zoo sits on 42 acres and houses roughly 1,300 animals representing more than 300 species, drawing between 1.2 million and 1.3 million visitors annually, per the same outlet.
The zoo also uses its Community Access Program, or CAP, to offer free or low-cost admission to Title I K-12 school field trips and to residents of neighboring West Philadelphia zip codes, including 19104, 19131, 19139, 19143 and 19151. That outreach effort runs alongside the zoo's broader push this year, which has also included a summer African Culture Fest held in partnership with Odunde365, and a citywide America 250 scavenger hunt that has been handing out zoo admission passes as prizes.
Part of a Bigger Halloween Trend at Zoos Nationwide
Philadelphia's move to stretch its Halloween event across more weekends mirrors a pattern playing out at other major zoos this fall. Detroit Zoo expanded its own Zoo Boo hours and dates for 2026, and Cleveland Metroparks Zoo likewise broadened its fall Halloween offerings this season. Tickets and additional details for Philadelphia's event are available through philadelphiazoo.org.
