Since the introduction of GST on 1 Apr 2015, Gua Tempurung started dual pricing, for locals and foreigners.
For example the cost of Tour 3 has increased from RM11 to RM40 and add on GST at 6% makes the price RM42.40 for foreigners.
See letter on Ipoh Echo 211.
I hope foreigners will boycott the place!
