Strollers are usually okay, but you might need to fold them.

Depends on the observation deck, but most allow strollers in the elevator and on the deck itself — with the caveat that you may need to collapse it in crowded spots.

The main concern is space. Elevators in major landmarks like the Empire State Building or One World Trade Center are designed for crowds, so they accommodate strollers. The observation decks themselves are generally stroller-friendly (smooth floors, railings, wide walkways). But during peak hours, security or staff may ask you to fold the stroller to keep walkways clear or prevent tripping hazards.

Some decks (e.g., Top of the Rock) have a strict “no strollers on the outdoor deck” rule during busy times, or they require you to use a carrier. Others have a designated storage area where you can leave the stroller while you go up.
