We booked via Coconut Tours a 17 days trip to discover the country of Sri Lanca.
Our young friendly driver Kasun was a bit shy at the beginning but after a few days much more than just a driver for us. His driving was perfect and cautious and it got more and more as a trip of three guys traveling together.
Take the chance and use this kind of transportation in the country. I am glad that I choose this instead of driving with a rental car by myself.
