‘Do as the locals do’ It’s a classic traveling phrase that you’ve probably heard before, but it’s a classic for a reason. The cheapest and best food in any country is the food that is eaten by the local people.
Everything becomes cheaper if you travel with another person. You can share rooms or a bed, split the cost of transport, even share meals if you like. Plus it’s always nice to share your adventure with someone!
If you’re exploring a new city then walking is always going to be the cheapest option. Do your research beforehand (or use apps like Google Maps or Maps.me) and plan to walk when you arrive. Obviously this won’t always be possible but as long as you are willing to walk then you’ll always be able to save money.
