Kiu Tsui Country Park, Coastal country park in Sai Kung District, Hong Kong.

Kiu Tsui Country Park spreads across eight islands in Port Shelter, with Sharp Island serving as the main destination for beach activities. The park features sandy and pebbly coves, rocky shorelines, and flat walking paths that connect the islands.

The park was established in 1979 to protect these islands, which formed 140 million years ago from the High Island Supervolcano. Volcanic rocks called tuff and breccia make up the foundation of this distinct landscape.

The park's eight islands take their names from Cantonese: Kiu Tsui Chau is Sharp Island, Kiu Tau the islet tied to it by a tombolo at low tide, and Hap Mun Bay carries the name "Crescent Bay". Two gazetted beaches, Hap Mun Bay and Kiu Tsui, are managed for swimming, so bathers share the coves with the boats that ferry them from Sai Kung Town.

You can reach Sharp Island by regular boat services from Sai Kung Town pier, with the journey taking around 15 minutes. Bring water, sun protection, and comfortable footwear, especially if you plan to walk between the islands.

During low tide, a natural sand levee emerges between Sharp Island and the smaller Kiu Tau islet, creating a rare walkable passage. This temporary path only appears at certain tidal stages and draws visitors seeking this fleeting experience.
