This climb to the rim of the karst wonderland may be short (about two hours), but you earn every step on the near-vertical ascent. You'll quickly forget your pain as the fortress of pinnacles and ridges unfolds before you, begging you to continue into the great unknown. Do not even consider this hike in the rain, as the trail turns to grease.

Guides can be organised in Merabu and the hike can be combined with a trip to Danau Nyadeng.
