Trio Beach, Bathing beach in Sai Kung District, Hong Kong.

Trio Beach is a 131-metre gazetted beach facing Sam Sing Wan on the Pak Sha Wan Peninsula in Sai Kung District. A rocky outcrop and a lifeguard tower split the sand into two sections. Facilities include 20 barbecue pits, changing rooms, showers, toilets, a refreshment kiosk, a water sports centre and a playground, with fish rafts moored nearby.

The beach grew as a destination after the Sai Kung area became known for water activities and recreational use. Safety improvements, including lifeguard services, made it a more secure place for swimming and helped it become established among local visitors.

The beach draws visitors on weekends who gather to swim, rest, and enjoy time together in this sheltered cove. People use the space casually, spreading out across the sand and rocks to make the most of their time away from the city.

The beach is reached by kai-to from Pak Sha Wan Pier in Hebe Haven, a crossing of about 15 minutes, or on foot over the Pak Sha Wan Peninsula. The sand is split in two by a rocky outcrop and a lifeguard tower, so bathers pick a side. A refreshment kiosk, changing rooms, showers and toilets stand on site.

Trio Beach is split in two by a rocky outcrop and a large lifeguard tower, so the cove reads as two separate stretches of sand. The beach measures 131 metres and has been rated good to fair for water quality by the Environmental Protection Department over the past twenty years.
