Haikou's parks are free. Jinniuling Park has four doors. It is recommended: get off at the north gate facing the Hainan Military District. You can take a photo with Jinniu at the door, and then follow the road on the left to the entrance of the East District Courtyard. During the period, you will pass the martyrs' cemetery (you can hang it), pigeon house (feeding). The zoo really does not recommend spending 30 yuan in the ticket, then returning to the coconut palm garden for a small nap, and finally exiting the Jinken Road from the south gate. It takes about 3 hours.
