Traditionally, the observatory has been open to visitors about 4 days per year, with perhaps 6 groups for each day. This year, they’re going to have 20 open days, but most of them will only have one group. Each visit starts at 9:45 with a visit to the MAGIC gamma-ray telescope, followed by one other telescope, and finishes before 12.00.
