Wheelchairs are available at the Turbine Hall entrance gate desk, and motorized scooters at the Featured entrance gate desk, at no charge and on a first-come, first-served basis. ID is required as a deposit. All exhibit and lab areas are wheelchair/scooter accessible with the exception of the USS Blueback submarine and some parts of our featured exhibit, Mazes. While all exhibits and labs are visual, many have additional auditory or tactile components that invite visitor participation. Staff are available to assist visitors in all exhibit and lab areas.
