Actually, no subway can take you there directly, so you have to transfer to a bus to arrive. Say, take subway Huanzhong Line or Shekou Line to get off at Huangbeiling Station. Getting out from exit C, you can walk to Xinxiu bus stop to transfer to bus no. 382 to garden directly.

The bus journey takes about 30 to 40 minutes to reach the garden from Huangbeiling Station.
