This goes hand-in-hand with your overpacking. But whilst avoiding overpacking is important, it’s also important to consider the weight of what you are packing. Remember, you’re going to be carrying your backpack around with you. And if you’re on a real low budget, then you’ll probably be walking from train stations to your accommodation. It’s therefore important to test the weight against what you can actually carry. Pop your backpack on and go for a 10 minute walk, you’ll soon find out whether it’s too heavy or not.
