If you have been to Sri Lanka but have not experienced a tuk-tuk ride, your experience is incomplete. The most popular mode of transport in the city, a tuk-tuk is a three-wheeled taxi. Riding one is similar to riding a roller coaster, as it weaves in and out of the Colombo traffic. The vehicle does not come with seat belts, and is open to elements from both sides. Hold on for dear life, and enjoy a ride of a lifetime.
