What to bring with you when you travel especially going far away from your country? Well, it depends on what you are aiming for or purpose of the trip and its duration. Certainly you need a valid international passport (and perhaps a visa), enough money, a few clothes and toiletry (proper clothes to suit the weather), some medication (if you are taking it on regular basis), a good bag (which can withstand rough handling) and a good walking shoe. This is only basic. Of course, you may consider many other things or gadget to bring with you such as snack, map and compass etc..
To me, it is now important for you to bring with you a digital SLR camera. You can record your travel or journey and share with your friends. "A picture is worth of a thousand words", so they said. Investing in a good dSLR camera is worthy venture.
