Vietnam is a country split between the city and the countryside. Few other places have such an immense divide inside their country. The fast paced city where every street crossing is a game of Frogger and seems to never slow down is much different to the welcoming and laidback feeling of the countryside. Ho Chi Minh City's glitzy downtown with never-ending pool parties and skyscrapers is a far cry from Phong Nha's hidden caves. The diverse landscape throughout allows for some of the best adventures including numerous UNESCO World Heritage sites and waterfalls.
