Re: WC 150K Post Challenge - You Ready?!
Some of the things we ended up doing:
The castle, it's huge complex and takes time to go in it. You don't have to go in everywhere but it's neat to see.
The Charles Bridge is nice and you can get some really nice photos of it at sunset and even at night.
The old town is pretty cool. You have to see the astronomical clock, just because.
We went around and saw some of these -
A tour of David Cerny's Prague - Prague Hotels and Travel Guide
There were other things as well including a trip to that church.
We didn't do a river cruise. We heard it wasn't recommended as you don't see much. When we got there we had to agree but it's up to you.
