In Britain, we still calculate distances in miles and we still drive on the left. Though just to be difficult, there is one road in London, near the Savoy Hotel, where you have to drive on the right! Many of Britain’s roads follow ancient Roman roads and you have to pay at some old toll bridges dating back hundred of years. In London, we still have red double-decker buses and black London cabs. Before they can work, London cab drivers still have to spent about 18 months learning all about the streets of London to get ‘the knowledge’.

However, not every thing about British transport is as it used to be fifty years ago. There are now more than 25 million cars on our roads so traffic jams are common on Britain’s motorways, like the infamous M25 around London. There are also problems with railway. To improve the situation with transport, the government is investing a lot of money in the railways and coming out with ‘new’ ideas like toll motorways and congestion charges in major cities like London.

There are some fantastic ways of getting around the country and enjoying yourself at the same time. For example, you can go on a cyclist holiday. Britain has thousands of miles of quiet country lanes and forest tracks, which are ideal for keen cyclists. There are even more footpaths for walking. For more adventurous, there are plenty of places for horse riding and canoeing as well as hang-gliding, paragliding and ballooning.

If you want something a bit safer and less energetic, go on a narrow boat. Britain has a great network of canals, a lot of them going through spectacular countryside. Another relaxed option is to go on one of Britain’s many stream railways like Severn Valley Railway or the Snowdon Railway, which goes up the highest mountain in Wales. Just sit back and enjoy it!
