Floating on inflatable tubes down the river in a cave is quite an experience. Especially if this cave is as beautiful as Goa Pindul. Located at Gunung Kidul, Yogyakarta region, not far from the town of Wonosari, the caves were formed by karst with an underground river. The mysterious atmosphere is enhanced by clusters of bats and sparkling stalactites and stalagmites.
On your way to the caves, a raft will take you down the Oya River, with some stunning waterfalls and small rapids. Those who seek more adrenaline can try optional cliff jumping. For many visitors, this is the best part of the tour!
One might assume that tubing, like rafting, should be more exciting during the wet season due to higher and faster water. However, it is better to opt for the dry season from May to September. During the dry season, the water in the cave has beautiful green color, while during the rainy months it gets brown and seems dirty. Also, the caves might get overflooded and hence will be closed to visitors. In any season, it's better to avoid the holidays and weekends because the cave gets too crowded, and it becomes challenging to find a spot to jump off the cliff.
