Ratu Boko Palace, a beautiful place, beautiful, cool, very quiet, plus drinking coconut milk under the shady trees. An unforgettable experience. We booked a through ticket to Prambanan Temple and Ratu Boko Palace, because there is a shuttle bus from Prambanan to Ratu Boko. It turned out that the shuttle bus was only available if you booked directly on the spot, not online. This was a mess and very disappointing. In the end, I went there by motorbike, it was quite far and quite a climb to get there. If you take the train, then see the mountains near Brambanan station/before the airport, that's where Ratu Boko is. It's quite far and uphill, but it's really nice and once again, use sunscreen because it's incredibly hot.
