Chujado Island is a group of four inhabited islands, called Sangchujado, Hachujado, Chupodo, and Hoenggando as well as 38 uninhabited islands. The majestic peaks of these islands makes Chujado look as if it were the top of a mountain. The dazzling array of islands is home to rich habitats of fish from yellow corvinas to hairtails, Japanese Spanish mackerels, snappers, bass, and horn fish, andd as such, it is a popular place for sea fishing. The main natural and cultural attractions include the habitat for black wood pigeons and streaked shearwaters (Natural Monument No.333), General Choi Yeong Shrine, and Chuja Cheosa House. Jeju City opened Chujado Olle Trail (or Jeju Olle Trail 18-1) in June 2010. Stretching over 17.7km, the trail begins at Chuja-myeon Office and connects peaks in Sangchujado (the largest island in Chujado) and Hachujado. Because of the numerous peaks, the trail is more of a hiking trail than a simple walking path and is easily one of the most demanding trails on Jeju Island.
