SF Zoo Free Admission Day

The San Francisco Zoo, Northern California’s largest zoological park and conservation center, periodically offers free admission for San Francisco residents.

When is the next free zoo day for SF residents?

– Next verified free day – Sunday, February 2, 2025 – Groundhog Day – please note that unlike the typical “free day” that’s only for SF residents, this special “Groundhog Day” promotion appears to be free for everyone!

The free days are often the first or second Wednesday of the month. However, dates often announced on VERY short notice with as little as 24 hours in advance and sometimes months are skipped altogether. Check the calendar.

This urban oasis, nestled against the Pacific Ocean, provides a comfortable climate all year round.  You’ll enjoy seeing the 250 different animal species in naturalistic surroundings, along with their many zoo activities and events.
