Bangkok is a city that never sleeps; it buzzes and pulses all night long, which is probably why it's so popular among backpackers on their gap year.
Bangkok has firmly established itself as the party city of South East Asia and often it's the first port of call for backpackers. It's also the central hub to get to other South East Asian countries such as Burma, Cambodia, Laos, Malaysia and Vietnam.
If you're looking for day time activities then things don't get much more magnificent than the Grand Palace. Situated right in the heart of Bangkok, it draws millions of visitors a year. You can easily spend hour after hour walking around in your own little bubble taking in the splendour and spirituality of this little city in a big city.
And just round the corner is the equally-alluring Wat Pho, also known as the Temple of the Reclining Buddha (if you've see The Beach then this is the one in the opening scene). Both places are perfect examples of what you've got in store for you in your time in Thailand.
Bangkok is a city to get lost in and catching the sky train to one of the suburbs shows you what life in the city is like. If that's a little too much though, you can take a tour of the floating market and get caught up in the cacophony of sights, smells and sounds going on around you.
And if you like things on the larger scale then shopping at MBK is for you. One of the biggest shopping malls in South East Asia, it's got everything you could possible want from cheap t-shirts to designer wear to a cinema on the top floor (an experience in itself).
No trip to Bangkok would be complete without trying the street food. Found on every other corner, you can chow down to some spring rolls or get messy with a paad thai. Or if you really want something weird and wonderful then chomp your way through deep fried cockroaches and crickets. Of course, to really complete the experience you've got to have a Chang or two (just beware of the Changover) and party on the infamous backpacker's Khoa San Road.
The best thing to do in Bangkok is experience it for yourself; open your eyes to one of the fastest growing cities in the world and strap yourself in for one of the wildest rides on your gap year.
