1 I don't know which CUHK you are (if you are in the university town, take subway line 4 directly, if you are in the old campus, you can transfer to line 4 after getting on the subway), get off at Jiaomen Station, get off at Jiaomen Bus Station, take Nansha Bus No.4, and you can get to the seaside at Nansha Bay.

The beach is next to Tianhou Palace. You only go to the beach, and there is no charge!

The distance from the beach to Wankui Garden is more than 30 kilometers. The nearest hotel to the seaside is Nansha Hotel, where there is no hotel (I know a hotel that has just been reclaimed from the sea, but I don't know where it is).
