Bus from Dengfeng (Shaolin Temple) to Kaifeng

Yes, there are direct long-distance bus between the two places. The bus station is on the west part of Zhongyue Street.
The bus takes about three hours, but it is not frequent. There are two one day, one in the morning and the other in the afternooe. I only take the bus at 15:00 in the afternoon and not very clear about the time in the morning.
The bus from Dengfeng to Zhengzhou is frequent and it is also frequent from Zhengzhou to Kaifeng.
