Aimen Beach sits in Xiyu Township and is the largest and longest natural beach in Penghu, stretching approximately 800 m (2,600 ft). The bay curves gently, with fine golden sand and clear water shallow enough to see the seabed — making it a main recreation spot for both residents and visitors. During spring tides, low water exposes a wide intertidal flat and creates the “Moses Parting the Sea” effect: visitors can walk along the exposed sand path out toward the middle of the sea, one of Aimen Beach’s most distinctive natural features.
Highlights
The sand at Aimen Beach varies in texture: the sand nearest shore is finest and palest gold, while it becomes coarser toward the water, mixing with seaweed fragments and broken shells. At low tide the entire beach is exposed; standing at the low-tide line you can look north toward the Penghu Cross-Sea Bridge and south toward Xiyu Lighthouse, with open views in both directions. As the tide rises the beach gradually submerges and the water shifts from pale green near shore to deep blue. At sunset the sea surface takes on a warm golden cast, which draws photographers to the beach in the evening.
The intertidal zone supports a range of marine life: sea stars, sea urchins, and hermit crabs are visible in tidal pools at low tide, and squid sometimes approach shore in summer. In winter, cormorants and grey herons forage along the shoreline. Scattered rocks at the southern end of the beach attract fish, and snorkelers can spot grouper and other reef species common to Penghu waters.
Getting There and Nearby
From Magong city center, take a westbound bus toward Xiyu (green line routes 31, 32, 34, or 35) to the “Aimen Beach” stop (PEN299822 or PEN299883) for direct access; the journey takes about 25–30 minutes. Alternatively, alight at “Aimen Roundabout” (PEN299823) and walk 5 minutes. Bus frequency may vary by season — call the Penghu County Public Bus and Ferry Authority at 06-9213822 to confirm the day’s timetable before setting out. Free parking is available in front of the beach, but spaces fill up quickly during peak season (June–August); arriving early is advised.
Convenience stores and small eateries are located near Aimen Roundabout; Xiyu Township market is 800 m (0.5 mi) from the roundabout and sells drinks and chilled items. Aimen Fishing Village, which preserves the layout and character of a traditional Penghu settlement, is a 15-minute walk north. Xiyu Lighthouse — the westernmost lighthouse in Taiwan — is 2 km (1.2 mi) from the beach and reachable by bus; the Penghu Cross-Sea Bridge viewpoint is a 10-minute drive and can be combined on the same itinerary. Daiyi Temple in Zhuwan and North Sea Music Island are at the southern end of Xiyu and require a separate visit.
Visitor notes: Summer is peak swimming season with lifeguards on duty, though the beach is busy. Spring and autumn offer milder water temperatures and fewer visitors. Winter brings strong northeast monsoon winds and large waves — unsuitable for swimming but manageable for a walk along the shore. To see the tidal sandbar, check the day’s tide schedule in advance (local government or fishery association websites); the phenomenon is most visible during spring tides at low tide. Bring sunscreen, water shoes, and drinking water — there are no showers at the beach.
