This seems to be the most appropriate thread, although a little old.

I swim and would like to swim while visiting Beijing in a few weeks. I've swum in a few Olympic pools (Munich, Barcelona, and Tokyo), and would love to swim in the Water Cube.

According to this site:

Much of the facility is now a water park. It looks like you can swim in the training pool for Y50.

Has anyone been out there recently? Would it be worth an hour+ trek on the subway each way to get there?
Anything else to see nearby? Looks like the rest of the Olympic park is there, anything notable I should see?
This will be in mid-November, so I'm guessing sunset will be by 6pm, so I could do something else first, then swim (since it is inside I don't need to waste daylight).

I'm sure there's other pools closer to my hotel, and I may try to swim at those too. But there's something about swimming in an Olympic pool ^
