Astropark, Astronomy park in Sai Kung District, Hong Kong.

Astropark is a 1,200-square-metre astronomy-themed park on the west dam of High Island Reservoir, within the Chong Hing Water Sports Centre in Sai Kung. It is divided into three zones: an astronomy study area with replicas of eight ancient Chinese instruments, a naked-eye viewing area with reclining constellation chairs, and a telescope viewing area with five 20×80 binoculars and ten telescope piers.

The park opened in 2010 as a public astronomy education facility featuring both historical and modern instruments. Since its establishment, it has served as a place where people can learn about the stars and practice observation.

The study zone displays replicas of eight ancient Chinese astronomical instruments, including the armillary sphere, star dial, moon dial, yangyi, gnomon-shadow table, equatorial sundial, horizontal sundial and zhengfang'an. A human sundial lets visitors read the time from their own shadow on the ground markings, and a pavilion shows a simulated starry sky on cloudy days.

The park is open around the clock, so night observation is possible at any hour. It sits on the west dam of High Island Reservoir, inside the Chong Hing Water Sports Centre, and covers about 1,200 square metres. Bring your own telescope or camera if you want to use the ten telescope piers and the two manual equatorial mounts.

The park features special reclining benches positioned for comfortable constellation study without strain on the neck. This thoughtful design encourages visitors to spend more time observing and learning about the patterns overhead.
