"Gua Kelam's one scared me a bit because it was suspended and a bit shaky. Water runs under the walkway so try not to drop your camera when taking photos. The cave was well-lit but unfortunately, filled with graffiti. Many visitors can't resist the temptation to write their names on the cave walls like the cavemen.I was pleasantly surprise to see many visitors. Until I realised that they don't care about the cave. They were there for the river! To 'mandi sungai'."
