Lao Cai Border Marker... Board Number 103.

Most tourists usually take a sleeping bus directly to Sapa, so they rarely visit Lao Cai. There doesn't seem to be much to do here either. However, for those traveling by train, Lao Cai is an inevitable gateway. Since you're already here, whether you're visiting from Sapa or stopping by because of the train, it's a rule to take a look at the other side of China. Next to the border immigration office, there is a border marker pointing towards the Chinese immigration office on the other side, which is a popular photo spot for many tourists.
