The trip involves crawling in a slippery cave, getting covered in bat's shit, sweating in the dense jungle, getting bitten by mosquito, fleeing away from wild dogs, getting sunburn, and riding a motorcycle through the storm with about 30 cm high water flood on the way back home... But it was definitely worth all of this: the well-deserved reward is a scary 100 meters multipitch abseil both along the crag and inside the cave.
