If you like to earn your food by exercising, then walking up the steps to Batu cave outside Kuala Lumpur may be your idea of a good time. This is a Hindu site and it’s really not that many steps. Be warned about the monkeys. Too bad that there is so much trash all about on the inside. It is a holy site and no admission is charged (though you can make a contribution, I think).
Then, eat some dhosa at one of the stalls on at the base. Or go back to the hawker stalls in KL and enjoy.
