Beiguan Park, also known as Lancheng Park, is located in Gengxin Village, Toucheng Township, at the northeastern tip of Taiwan. At its southern end lies the counterpart “Nanguan,” together forming an important gateway to the Lanyang Plain since ancient times. During the Qing dynasty, Beiguan served as a military checkpoint. Due to its strategic terrain, it was considered the best location to defend against bandits attempting to enter Yilan, and troops were stationed there by imperial decree. Two ancient cannons, said to have been cast during the Jiaqing era, still stand in the park as historical witnesses.
The park’s most distinctive feature lies in its unique natural landscapes. Over millions of years, relentless wave erosion sculpted formations such as cuesta ridges, tofu rocks, and small coastal capes, creating a striking stone forest representative of Taiwan’s northeastern coastal geology. Stair trails, seaside pavilions, and viewing decks have been developed, allowing visitors to stroll through and admire nature’s artistry.
From the Seaside Pavilion, one can enjoy sweeping views of Guishan Island and the Waiao coastline, with the entire Beiguan area spread out below. The scenery contrasts the tranquil beauty of distant Guishan with the roaring waves crashing onto the rugged shore nearby. Especially during high tide or sunrise, the powerful waves and resounding surf echoing among the rocks vividly embody the grandeur of “Beiguan Sea Tides”, one of the Eight Scenic Wonders of Lanyang.
