1. Always pack a towel
It’s the key to successful galactic hitchhiking and plain common sense. You never know when you will need it, whether it’s at the beach, on a picnic, or just to dry off. While many hostels offer towels, you never know and carrying a small towel won’t add that much weight to your bag.
2. Buy a small backpack/suitcase
By purchasing a small backpack (I like something around 35/40 liters), you will be forced you to pack light and avoid carrying too much stuff. Humans have a natural tendency to want to fill space so if you pack light but have lots of extra room in your bag, you’ll end up going “well, I guess I can take more” and then regret it.
3. Pack light
It’s OK to wear the same t-shirt a few days in a row. Take half the clothes you think you will need…you won’t need as much as you think. Write down a list of essentials, cut it in half, and then only pack that! Plus, since you bought a small backpack like I said, you won’t have much room for extra stuff anyways!
4. But take extra socks
You’ll lose a bunch to laundry gremlins, wear and tear, and hiking so packing extra will come in handy. I only take a few more than I need. Nothing beats a fresh pair of socks!
5. Take an extra bank card and credit card with you
Disasters happen. It’s always good to have a backup in case you get robbed or lose a card. You don’t want to be stuck somewhere new without access to your funds. I once had a card duplicated and a freeze put on it. I couldn’t use it for the rest of my trip. I was very happy I had an extra and not like my friend, who didn’t and was forced to borrow money from me all the time!
