Manila's roads are notorious for heavy smog and traffic congestion, especially at peak hours. Public transport is inexpensive and plentiful, though, and includes the elevated light rail system (LRT) and the Metro Rail Transit (MRT). Both have helped to alleviate some of the congestion. However, public transport can also be dangerous in the Philippines and travellers should exercise vigilance.The elevated light rail system is a good option as it is fast, clean and efficient. It's very crowded during the evening rush hour, though. Many bus companies comprehensively service the city too, and local jeepneys (brightly coloured minibuses) can be hailed anywhere.Buses and jeepneys are the cheapest form of transport for areas not covered by the LRT. Taxis are inexpensive and convenient, provided that passengers always agree on a fare before setting off. Travellers can also rely on calesas (horse-drawn carriages) for short trips. Tricycle pedicabs are available for hire, and the ride-hailing service, Grab, is another option.
