The castle is located to the southwest of the Royal Palace and would have been extremely grand in its time and made up of a network of pools, streams, and royal buildings for the enjoyment of the sultan and his family.
Nowadays it has fallen into disrepair and much of the water palace is gently crumbling, although this adds to the experience and you can spend an afternoon wandering around the graceful ruins which date from the 1700s. You will also find a section of underground tunnels which are not to be missed and you can take a guided tour for a small fee or simply go it alone.
6. Kalibiru National Park
Need we warn you, this one is not for the faint of heart.
Up the Menoreh mountain range lies Kalibiru National Park, which is built and run by the local residents since 2009. Unlike most parks that offer the regular outbound activities, the rock climbing and tightrope walking at the Kalibiru National Park is fully scaled and comes with an amazing view from the top of a mountain. Take a 1-2 hour’s drive westward from the city and you will immediately notice the decrease in temperature and vanishing buzz of motorcycles.
Make the experience even more daring with the flying fox that ends at a deck on top of a tree with a view overlooking Lake Sermon. You might just see the white waves of the south seas crashing on the beach.
7. Visit Prambanan Temple
Built in the 10th century, this is the largest temple compound dedicated to Shiva in Indonesia, Prambanan Temple comprises the remains of some 244 temples. It is listed in the Unesco World Heritage Site in 1991.
The highlight is the central compound, where eight main and eight minor temples are assembled on a raised platform – an architectural crescendo of carved masonry and staircases, the high note of which is Candi Shiva Mahadeva. Prambanan sits within a large park dotted with lesser temples. The temple suffered extensive damage in the 2006 Yogyakarta earthquake. Although the main temples survived, hundreds of stone blocks collapsed or were cracked (479 blocks in the Shiva temple alone).
