How much luggage is toooo much?

Anything you need for more than one week is too much. I.e think about what you would wear in one week. In a hot country, two pairs of shorts, one pair of long trousers or a long skirt, maybe a dress and a few tees, no more than that, obviously not forgetting the knickers and bras. This will be repeated and sometimes boring but remember you can can always replace things as you travel. Personally, I love taking a couple of old tees and a pair of old shorts so I have the excuse to buy some new ones, particularly if you are travelling for two or three months.

What size luggage? Depending on whether it is a hot or cold country. I only travel with a 40L What I tend to do is get he 40L back pack and then only allow enough clothes to fit in. Be warned, you will soon get fed up of packing and unpacking large, full rucksacks and carrying, large, big back packs on journeys. You will really appreciate a 40Lwhich is comfortable enough to carry and can take everything you need if you pack wisely.

Packing is a really important a part of planning.
