Hoi Ha (Chinese: 海下; Jyutping: hoi2 haa6) is a place and a village on the innermost shore of Hoi Ha Wan, Hong Kong. It is at the north of Pak Sha O in the Sai Kung Peninsula.
One of the most famous heritage spots in Hoi Ha Wan is the remnants of the lime kilns. It was used to make lime from sea shells and coral. It was likely built in the early 1900s.
The name Hoi Ha comes from the same Hakka language word which broadly translates as Seashore or Seaside in English
