The distance from the dock to the prison at the top of the island is about 1/4 mile (.4 km) and the elevation change is 130 feet (40 meters). This is roughly equivalent to climbing a thirteen story building, but spread out over 1/4 mile.

Visitors unable to make the climb up Alcatraz's steep road due to mobility needs can take advantage of SEAT—Sustainable Easy Access Transport—an electric shuttle that runs twice an hour from the dock to the prison building, and twice an hour from the prison to the dock. The tram can not stop on the hill, boarding is only at the dock and the cellhouse. Boarding is available on a first come, first served basis. SEAT can accommodate wheelchair users. Only those individuals with mobility or physical needs may ride the shuttle - other members of your party cannot be accommodated except an attendant. 

There are no wheelchairs available for loan on Alcatraz Island.

Transcripts of the Cellhouse Audio Tour and other interpretive materials are available for loan upon request for visitors unable to utilize the audio tour. Videos shown on the island are open captioned.
