If you can’t find availability online for your desired date, you have 2 options:

Option 1: Go directly to the ticket office on the day of your visit,as early as possible, (opening of the cash desk at 6:00 am) to buy tickets for a later departure that day, subject to availability.

Option 2: Every day at 5 p.m., additional time slots are released online on our website for visits taking place 48 hours later.
