Getting around Beijing
There are plenty of ways to get around this enormous city. Beijing has an extensive bus and subway network to get you where you need to go. The subway is fastest and easiest, but will be very crowded during rush hour. Buses are always crowded. The taxis run off of meters, and are very easy to find, but many drivers don’t speak English, so it helps to have your destination written in Chinese. Cycle rickshaws are another option, but you will have to bargain your rate, and some drivers demand more when you arrive at your destination. You can also rent a car and driver for the day, or rent your own car. Be aware that you won’t be able to leave the city limits if you’re driving.
The city is too large to walk, but you can certainly take public transport or a taxi to a particular area and then explore on foot. If you are brave enough, rent a bicycle and ride alongside the busy traffic.
Biking is very popular in Beijing and bike lanes are clearly marked. If you get overwhelmed, go with the flow of cycling traffic, especially when crossing streets.
