Travel Tips:
Hainan has better transportation among the regions in Qinghai Province. Qinghai-Tibet Highway (National Highway No.109) and Qingkang Highway (National Highway No.214) all run through the prefecture. The south line of the Qinghai-Tibet Highway passes through Nanhai, running westward through the mouth of Riyue Mountain along the south bank of the Qinghai Lake.

Daotanghe Town is a vital stop on these two highways. It is beside the Daotang (Backflowing) River of Riyue Mountain. Departing from the town, Qinghai-Tibet Highway stretches westward to contact with Haixi Mongol and Tibetan Autonomous Prefecture, while the Qingkang Highway runs to the southwest and gets to Guoluo and Yushu Tibetan autonomous counties.
Bus station in Gonghe County is located at 9, Lvzhou Nan Lu. Furthermore, each county has its own bus stations in the county seat.
