Yes. A pushchair/buggy can come with you onto the Coca-Cola London Eye but it must remain completely closed/folded throughout the experience, and on the entrance and exit ramps. Please make sure you therefore fold down your buggy prior to joining the boarding queue and open it back off once you are clear of the exit ramp.
If you have a buggy that does not collapse, it can be left at our 'Buggy' area facility in the ticket hall, although only for the duration of the experience. Please note: space is very limited and no bags or personal items can be left with the pushchair/buggy.
