Elder Rock Introduction
Old Man Rock, as its name suggests, resembles an elderly person who has gone through many trials. By crossing the grassy plains of Hongtou Village and climbing the cliffs, one can reach Old Man Rock, which is composed of coral reefs. Viewed from the sea, Old Man Rock is particularly distinct, and the rock formations have a rich exotic island flavor, offering a truly unique landscape. The geological formations of Lanyu mainly consist of andesitic lava and basaltic breccia with amphibole, as well as Pleistocene red clay layers, uplifted coral reefs, and Holocene alluvial layers, debris flow layers, and coastal skirt reefs. Through the processes of marine erosion and weathering, Lanyu has sculpted its most intriguing rock formations. Old Man Rock is a coastal erosion landform, surrounded by a volcanic crater that makes climbing the steep rocks challenging. At its peak, it preserves Lanyu’s precious Chinese juniper. Growing in a difficult-to-access area, it remains untouched by human destruction and represents a well-preserved plant landscape. In addition to Old Man Rock, Lanyu is also known for its remarkable rock formations such as Hongtou Rock, Crocodile Rock, Twin Lion Rock, Dragon Head Rock, Mother Hen Rock, Jade Girl Rock, Five Holes Cave, Tank Rock, Steel Helmet Rock, Mantou Rock, and Warship Rock.
