Colombo is the Capital of Sri Lanka. The city offers a jarring architectural mix of old and new. You will experience a central cluster of high-rise office blocks and hotels overshadowing red-tiled colonial-era buildings. It doesn't get less crowded but definitely a lot more fun once you arrive at one of the sprawling street markets. Expect an overflow of high-piled fruit and vegetables, colourful silks, cottons and deliciously fragrant spices.
