About Colombo
City overview
Colombo is Sri Lanka main city, where Fort offices, Pettah markets, Galle Face, Cinnamon Gardens, Buddhist temples, colonial buildings, and seafront hotels sit between airport and island rail routes. Treat it as Fort and Pettah for commerce, Galle Face and Kollupitiya for the coast, and Cinnamon Gardens or Borella for museums and parks.
Food & drink
Colombo food is hands-on and rice-based: hoppers are bowl-shaped fermented-rice pancakes, string hoppers are pressed rice-noodle nests, and kottu roti is chopped flatbread stir-fried with egg, vegetables, and meat. Pettah snacks, Galle Face carts, Kollupitiya restaurants, Dutch Hospital dining, and Mount Lavinia seafood add lamprais baked in a banana leaf, crab curry, isso vadai, short eats, and Ceylon tea.

120km / 2.5-3.5h by train or car from Colombo
Kandy

Getting around
PickMe, Uber, tuk-tuks, buses, and suburban rail handle most movement; Fort station and the Pettah bus stands are the practical transport anchors. Traffic is slow, so group Fort-Pettah, Cinnamon Gardens, and Mount Lavinia as separate clusters.
