You're sweating like a pig- and you don't normally sweat. It's loud and somehow crowded, despite the lack of crowds. Several official transport networks seem to exist simultaneously, but they don't talk to each other. Sidewalks are random and few. The city sprawls for what must be several light years. A jaunt up to the roof provides some context, confirming your fears.
Welcome to Kuala Lampur.
But then again, things are cheap. Except beer- this is a Muslim country after all. The food is interesting too. Chinese, Indian and 'other' provide a diverse set of gastronomic options. Finding it can be tough in KL, but you won't have to eat badly. There's some interesting things to see too, if you can find them. The river has some neat concrete banks to walk.
But if you're like me, the heat just makes you want to die. Oh well.
I figured I should visit the Batu Caves. Caves always sound cool, and caves with Buddist temples in them must be extra cool, right?
Protip: Don't take the slightly different train that goes 10 km in the wrong direction. It's an adventure back.
Realistically, you can afford to miss the Batu caves. The 40m statue is theoretically impressive, but its impact is lost in the scale of the place, as well as the heat. What's more, the 'temple' inside the cave is little more than a concrete paved trinket shop and dirty shrine. Perhaps impressive to some, but pretty dull to a jaded traveler like me.
