This cave, 9km west of the SS445 along a horribly narrow road, showcases a world of underground abysses, lakes and caverns. April to October, choose between a one-, two- or three-hour guided tour – if you're up to the 800/1200 steps involved in the two-/three-hour tour (!) it's worth it. November to March, the one-hour tour (300 steps) is the only choice.
