Take a bus at Shuiwan Road to No.609 Road (the end point) such as Qianshan Bridge East.
The second is to take a free car. However, if you have time, you'd better call first. Kyushu Port picks up guests (free of charge), and Imperial Hot Springs is toll-free at 4008999888.
Another brief introduction of Imperial Hot Springs:
You can spend the night in the Royal Hot Springs. You can stay in a special hotel. You need money. There is also a free hall. See below for details.
Ticket price of Zhuhai Royal Hot Spring 128 yuan (online booking is cheaper), which seems a little cheaper on weekdays? This price only includes other services such as hot springs, massage or SPA, plus one hour 45 yuan (but the technique is quite general); Only general drinks are provided; Free swimsuit.
Others:
There is also a hot spring bay in Zhuhai, which is relatively modern, with good hardware, a little international and a through train.
Personal advice:
Royal Hot Springs in Zhuhai, if you have been to hot springs in other places, you don't have to go, not much difference; On the contrary, Haiquan Bay (168/ ticket) can be visited, which is a little innovative, and there are other large amusement parks next to it.
