We are 9 peoples want visit The Great wall from Beijing downtown, what best vehicle to go there? thx

Is it Badaling section you are going to visit?
If so, both train and bus are available. Trains depart from North Railway Statio with an interval of about an hour while bus (919) departs from Deshengmen once fully occupied.

Thank you Robert for your reply
Yes Badaling section. How much the cost of train and bus? Which better when we rent a van? Because we want to visit Olympic Stadium and Ming Tomb first? Do you know the cost when we rent a van? Thank you

The train ticket is CNY 6 per person and bus ticket is CNY 12. If you get a transportation smart card, you can enjoy a 50% discount off the original ticket fares.

Of course, it's better to rent a van, which will save you time and trouble. For reference, a vehicle which can seat four passengers costs around CNY 1,000 per day (8 hours). As you have nine, the costs will be much more for a large vehicle. Sorry I'm not clear for the fee of that kind of vehicle.

I recommend you to the Wall first; on the way back to downtown,you can visit the other two. The night view of Olympic park is amazing.
