“Gua Musang is fairly close to the Taman Negara entrances at Merapoh and Kuala Koh, but the main reason visitors stop off is to explore the caves that riddle the mass of limestone above the town. Both the caves and the town are named after a small creature, the musang, which looks like a civet and used to live up in the caves; it’s now almost extinct. To get to the caves, cross the railway track at the station and walk through the small kampung in the shadow of the rock behind the station. Here you’ll have to ask one of the villagers to guide you (it’s usual to pay around RM10 for this); it is possible to reach the caves on your own, but the trail – which is directly at the back of the huts – is difficult to negotiate after rain, when it’s likely to be extremely slippery. Wear strong shoes and take a torch to use inside the cave. Once you’ve climbed steeply up 20m of rock face you’ll see a narrow ledge; turn left and edge carefully along until you see a long slit in the rock which leads into a cave – you’ll need to be fairly thin to negotiate this. The inside of the cave is enormous, 60m long and 30m high in places, and well lit by sunlight from holes above. The main cave leads to lesser ones, which have rock formations jutting out from the walls and ceilings. The only way out is by the same route, which you’ll need to take very carefully, especially the near-vertical descent off the ledge and back down to the kampung.”
