The observatory's official booking information directs drivers to park at Chilgap Plaza, 400m or about a 5–10 minute walk from the observatory. Driving directly to the building is not allowed. Large buses cannot easily reach the plaza on the narrow road and may require a roughly 40-minute walk from a lower car park. In poor weather, only a roughly 30-minute Full Dome film may be shown, without outdoor telescope observation. Reservations are canceled if tickets have not been purchased ten minutes before the visit; cancellation by the visitor is available until 16:00 on the visit day. Enquiries 041-940-2790.
