See this? Big, isn't it? It's Wat Arun, also known as the Temple of Dawn and if you're inclined to climb it you're supposed to do it at dawn. It's on the western side of the Chao Phrya river and is accessable from central Bangkok by ferry.
The view up there is tremendous. I took lots of pictures and started going down the steep stairs. But I couldn't do it. It was steep and I wanted to treat the decent as I would coming down a ladder. I turned my back to the river and my face to the steps but there were no rungs and the stone steps were hot. I retreated to take more pictures and to contemplate my next move. I'm afraid of heights and it's all stone so if I fell down the stairs I'd be lucky to survive.
