What it costs instead

The baseline without a free day: $25 adult, which puts a couple at $50 and four adults at $100 before extras. Bringing that down means the routes below: a membership that travels, a discount program you qualify for, or a library pass.

Upcoming free days

No upcoming free dates are published right now. COSI announces free days on its official page — that's the place to watch.

Know before you go

Who qualifies: No general-public free day; teachers free daily with verification.
Reservations: All visitors must reserve a date of entry; visit any time that day.
Worth knowing: The everyday freebie is for educators: certified teachers are admitted free any day with verification and photo ID — no special day required.

Other ways in, no calendar required

SNAP EBT cardholders should check Museums for All: at 1,700+ institutions nationwide, an EBT card plus photo ID admits up to four people for free-to-$5, on any regular day rather than a special one. The official list says whether COSI takes part.
Science-center members from 90+ miles away may get in on the ASTC Travel Passport — the 90-mile rule is the catch, and our reciprocity lookup computes it for your ZIP.

Dates don't line up?

Regular tickets ($25 adult) are on cosi.org — the official site is the place to buy; resellers only add fees. And if you hold a museum, science-center or zoo membership from another city, run it through our reciprocity lookup — it may already get you in.

The monthly date drop

Each month we send Columbus's verified free days in one short email: dates, who qualifies, done.
