- One of the best ways to explore London and the surrounding areas is by renting a car. You can drive to various parts of the English capital and nearby areas inaccessible by public transport. Renting is also much cheaper when you compare the cumulative costs of hiring a taxi to various destinations in and out of London. You can drive to Windsor, around 23 miles west of London, and explore the castle grounds and the charming town of Windsor, or head south to Brighton, a vibrant seaside town with a famous pier, beaches, and lively atmosphere.
- If you’re visiting London, you can fly into one of the city’s six major airports: Luton Airport (LTN), Heathrow Airport (LHR), London City Airport (LCY), Stansted Airport (STN), Gatwick Airport (LGW), and Southend Airport (SEN). These airports host different car rental providers, including Avis, Alamo, Budget, Enterprise, National, Hertz, SIXT, and Europcar. The journey time to the city center depends on your arrival airport and traffic. London City Airport (LCY) is the closest to the city center, around 9 miles. Heathrow Airport (LHR), London's largest and busiest airport, is approximately 18 miles from central London.
- Road conditions in London are generally good. They are well-marked and maintained. London is usually busy, so driving in the city center can be challenging due to high human and motorized traffic. Some parts of the city have narrow streets, which might be challenging to navigate, especially for tourists. You’ll also encounter several cyclists on the streets of London. Observe caution when driving in the city and be prepared to give way to pedestrians and cyclists. Watch out for bus lanes since many buses are serving the city.
