The "Shimen Cave," a popular attraction featuring a unique wave-eroded arch, is a famous landmark on the Northeast Coast. Its arch, formed by sea erosion and crustal uplift, stands tall on the coast. Another check-in point is the "Shimen Arch Bridge," also known as the "Lover Bridge". At dusk, the sunset dyes the sea red, creating a picturesque scene with the bridge that can inspire creative ideas for film and television productions. The viewing platform next to the parking lot is also an excellent place to watch the waves and relax. On clear days, visitors can also stroll along the trail, leading to a romantic seaside pavilion that offers stunning views of the expansive sea and sky.
Moreover, the shell beach next to Shimen Cave is ecologically rich, with hermit crabs, crabs, and small fish shuttling through the intertidal zone, attracting many families to come and explore the ecology. Every April and May, the area around Shimen Cave comes alive with the blooms of Taiwan lilies and Sedum formosanum, adding a touch of vitality and color to the scenery.
