Petrin Hill
I'm a sucker for a good view point and had read Petrin Hill offered the best view in the city. Take the funicular to the top like we did or have a leisurely stroll. Keep in mind - it's pretty steep! Once you get to the top make sure you pay a trip to the observation tower. Modelled on the famous Eiffel Tower in Paris, it was built in 1861. You'll have to suffer 299 steps before you reach the top but the view is absolutely stunning. Miles and miles of pretty terracotta roofs and every recognisable landmark will be in your sights. Make sure you have a wander around once you make your way down - it's a great place to bring a picnic.
City art
One of my favourite things to do in Prague was to wander around. There so many things on every corner so one of the best things is to just keep an eye out. Head to John Lennon Wall to see some street art. People have left so many messages and it's a really cool place. The giant metal babies are quite famous in the city. They crawl up the TV tower but you'll also find some in Kampa Park. They are meant to represent the communist era, unable to reach adulthood, stifled by totalitarian rule. The Memorial to the Victims of Communism is very moving and worth seeking out. Located on the edge of Petrin Hill, it was unveiled 12 years after the fall of communism.
Charles Bridge
My best tip would be to cross the Charles Bridge early in the morning so that you beat the huge crowds. Crossing the Vltava River, construction of the bridge was started in 1357 and was finished in the beginning of the 15th Century. Decorated with numerous black statues on either side, most of them in Baroque-style. It's also lovely to cross when the sun sets to see the city sparkling in the darkness.
Old Town
Again the old town is full of tourists so it's best to start your exploring as early as possible. The early bird catches the world. Its here that the atmospheric clock lives. This is a little underwhelming but it's worth seeing it as it's such a famous part of the city. It chimes on the hour and people start crowding round about 15 minutes before. The old town square is such a hub of activity and a great place to people watch.
Castle district
The castle district consists of Prague Castle, St Vitus Cathedral, Golden Lane and St George's Basilica. We paid to get in and see all these buildings but if I'm perfectly honest, I'm not sure it was worth the dosh. It's much nicer to just wander around the outside of the complex. As a Brit, I think we're pretty spoilt with castles in this country and Prague just didn't live up to the expectations. But definitely trek up to the hill and marvel at the architecture.
Pedalos on the River
Due to peer pressure from my friends, we decided to do this on the whim and it was one of my favourite afternoons. We hired a pedalo for an hour and laughed non-stop. It was pretty scary when we got a little too close to the weir but we made it back in one piece. It's a really fun way to spend an hour.
