To get into this national park, foreigners must pay a toll fee. This place sits magically on the top of mountains that have been used to build the temples of Angkor Wat. The water running from the beautiful waterfall is said to be holy and locals often bring a bottle of it with them home.

Take a padlock and key and take your sweetheart to Tumski Bridge, lock the padlock to the bridge and then throw away the key to Odra River. By doing so it is claimed to make your love stronger and make it last forever. You will also find out that you are not the only one; there are hundreds of padlocks on the bridge, with names, dates and short messages.

Stepping into the Frankfurt Zoo is like entering another world: hold on to your hat while you marvel at all the majestic African animals and the exciting, colourful world of Madagascar. The list of foreign and exotic places and settings goes on and on and there is a total of 4,500 animals and over 500 species from across the globe here. Apart from the fixed features, there are festivals, exhibits and themed tours to enjoy as well.

Enclosed within a protective wall reaching up to 20 metres in width, the Ciudad Amurallada (or Walled City) is Cartagena's old beating heart. Packed with well-preserved colonial buildings, it's a pleasure to stroll through; its streets of colourful low-rise merchant homes marked by iconic balconies are now mostly walked by either tourists or students who attend classes at the University of Cartagena during the day and linger for meals and nightlife after school is out. Cafes in Plaza Aduana and Plaza Santo Domingo teem with patrons, forging an incredibly jovial atmosphere; the districts of San Diego and El Centro are two not to be missed. There is plenty of food and shopping to be had, with a mixed bag of world-class restaurants and street food hawkers and the incredibly photogenic palenqueras — women dressed in vibrantly coloured clothing selling fruit in the streets — images of whom have become emblematic of Colombia as a travel destination.
