The best way to experience the Great Wall of China is of course to climb up the slope and stairs on your own. This may be quite tiring and require resting, especially if you are not so physically conditioned. Another option is to go up using the cable car but this requires more time and will be crowded during the peak seasons. There are various signboards in both Chinese and English which will show you your location and directions to all the different facilities, so it is actually quite easy to move around. Be careful of your belongings especially during crowded season.
The best way to visit the Great Wall and Ming Tombs is by a day tour, which include a comfortable bus, lunch and a English speaking guide. This will save you the trouble of organising your own trip and most of the tourist going there usually takes the day tour. You can book through the internet which will cost about US$60 per person (for 2 persons) and less if there are more people. However, it will be cheaper to book this day tour at your hotel in Beijing when you are there.
For those who want to visit the Badaling great wall on your town, the entrance fee costs RMB$45 per person.
After breakfast, we left Beijing towards the Great Wall by bus. It was an organised trip so everything on transport was organised.
We had no traffic jam; it was about 1h30 driving.
The view along the road was not very special, so most people were reading or even sleeping.
After our Great Wall visit the same bus brought us to Beijing airport were we took a light towards Lanzhou.
