Prague Castle, One Of The Best Place in The World
The castle during the day is impressive. There are lots of exhibitions and palaces to see and the cathedral is truly impressive. The golden lanes are also a must with the largest collection of arms and armour I've ever seen. The rebuild cottages showing what it would have looked like are amazing. We could gave spent more than one day there if we'd had the time. A good reason to return to Prague on it's own.
If you don't visit the castle your trip to Prague is a waste. There are 3 different kinds of entry tickets to choose from if I remember correctly, to visit different sites inside the castle. Reserve a whole day and be prepared to walk to enjoy the castle. It can be reached by the trans easily from the city. You can also take a scenic walk from old Town square through Charles bridge.
You have a minor grammatical mistake in the following sentence:
It should be its own instead of it's own.
