Purchasing the ticket was easy enough through Traveloka. However, we were disappointed with the whole experience, as being foreign visitors the tickets cost 380,000 IDR each. This only covered entrance to the grounds, so we could not enter the temple, just walk around its base. We did not have the option to purchase tickets to climb the temple on the day - I believe due to the fact they only issue a certain quota each day. Sadly we found this very poor value for money, and the whole experience left us disappointed.
