<]:^D wrote:clock is rubbish/charles bridge is a bridge hill with tower and observatory is good. take the cable car up though - its steep! the castle complex on another hill is great, you can get a tram up to it.
The walk made the pint near the top (by the magic cave) completely justified
Best way to see the astrological clock is from the top of the tower, so you can watch as hundreds of faces in the crowd below suddenly realise, yes, that was it. Charles Bridge is nice, but was heaving busy.
Definitely see the castle and the grounds around it, and the observation tower at night gives you a great view of the city. That's actually where I proposed to my wife, as well.
