Guests arrival and departure information
Parents and guardians dropping off their child for a birthday party may park in our loading zone for no more than 10 minutes. This loading zone is adjacent to our party room. All visitors staying for the duration of the party will need to park in our garage, explained below. Parents/guardians picking up their child after a birthday party should go to the Ticketing Counter and let an employee know which party their child is attending. A chaperone from the party will then escort the child down to the Ticketing Counter to meet their parents.
Convenient parking at the Science Center/Riverfront Garage is located at the corner of Grove St. and Columbus Boulevard, underneath the Science Center building. It is a public garage. Please know that the CT Science Center neither owns nor operates the Science Center/Riverfront garage. The fee is $3 for the 1st hour and $2 for every additional hour.
