Consider buying a train pass and walk if possible instead taking a cab
Trains are a great way to get around especially if you travel in Europe or Asia. Pre-purchasing a train pass is a money saver and trains are excellent for socializing. Walking is also a great way to get around and it`s good for your body. If walking is not an option try using metro or bus.
Shop in Grocery Stores for Food and Alcohol
Many restaurants, especially in big cities in Europe can be really expensive. On the other hand grocery stores are great for fresh food and authentic yet affordable meal. Bars can often overcharge tourist for drinks. The idea is to buy less in bars after drinking some in your hostel room.
Be flexible and change your route if needed
Stay open for recommendations and tips from locals or other fellow travelers. Seek for cheaper places to stay near your desired location and seek additional transport options in the surrounding area.
Backpacking is all about stepping into the unknown, so be prepared to go where the day takes you.
