Yes, you can experience Sri Lanka less than 50 dollars a day and even 10–15 dollars a day depending on how you select to explore. If you are backpacking, you can cut down the costs by always using public transport, eating from street food stalls, staying at hostels or Airbnb’s etc.
I have only covered the basics in the article. Depending on how travelers prefer to go about these suggestions, they have the freedom to manage their costs.
Thanks for your feedback :)
