Located in Huxi Township, Aimen Beach connects with Lintou Beach to form Penghu’s longest stretch of golden sand, extending about 3 kilometers. The sand is made up of coral fragments, crushed shells, and the remains of tiny marine organisms, including the star-shaped foraminifera known as “star sand.” Wearing footwear is recommended, as shell fragments can feel sharp underfoot.

Aimen Beach is also a popular spot for summer water activities, including jet skiing and banana boat rides, with options varying by season. Facilities include restrooms, showers, and rinsing areas. Located near Penghu Airport, it’s a convenient stop when exploring the area.
