Wat Ban Tham

The entrance is the hook: a staircase that runs straight into a sculpted dragon's mouth, then up through the body, past murals telling Buddhist history, to a cave temple where you can collect a blessing. Most people stop there, which is fair enough. But it's another twenty minutes or so of climbing to the peak, and that's where you get the long views over the river and the flatland below. Free entry either way.

Two things to be honest about. The cave gets crowded, and on a busy day it can be shoulder to shoulder inside, enough that some people give up on going in at all. And the steps get steep and uneven higher up, so this isn't a stop for anyone shaky on their feet. There's parking at the bottom and food and drink stalls at the low level, though seats go fast when a crowd turns up.
