Renting a Tuk-tuk is a very good idea for traveling in Sri Lanka because It saves you money and time compared to using public transport or a taxi service. The average rent price of a Tuk-Tuk is $18 per day. You also have fuel costs for your ride. However, a three-wheeler is fuel-efficient, so it does not take too much. You must make one-time payments for a Sri Lanka driver’s license and insurance.
