Along with the ferry ticket, visitors intending to enter the statue's pedestal must also obtain a complimentary ticket.[24] Those wishing to climb the 154 stairs to the crown within the statue must obtain a special ticket, which may be reserved up to a year in advance. Ten people per group, three groups per hour, are permitted to ascend, allowing for a total of 240 per day. After an obligatory second security screening, they may bring only medication and cameras, leaving all other items in lockers provided.[24] Visitors intending to tour Ellis Island's south side, namely the Ellis Island Immigrant Hospital, must purchase a "Hard Hat Tour" ticket, which charges an additional fee on top of the regular ferry ticket.[25][26]
