Completed in 2009, the Dongyang Mountain Trail is situated directly in front of the Eastern Jiu Service Station of the Matsu National Scenic Area Management Office, making it a new emerging tourist attraction in Matsu. Constructed along a steep cliff face, the Dongyang Mountain Trail offers expansive vistas of extensive grassland plains and natural geological formations such as sea erosion columns and grooves shaped through long-term natural processes. From here, visitors can admire the picturesque East Dog Lighthouse from multiple perspectives, while nearby lies the legendary "Mysterious Small Bay." Taking a hike on the Dongyang Mountain Trail to unwind is certainly a visit that will leave you with unforgettable memories.
