West Jeju: Korea's Highest Convenience Store, Two Horse Lighthouses, a Sunset Street

The day starts high. The 1100 Altitude Wetland on Hallasan is UNESCO-listed, crossed by a boardwalk over alpine bog, and it holds the highest convenience store in Korea, which is a better place for a hot snack than it sounds. Jusangjeolli comes next: basalt columns in hexagons, formed when lava hit the sea and cooled too fast to do anything else, with the water working at their base. Cheonjeyeon falls in three tiers through forest. It is called the Pond of the Gods, and the Seonimgyo bridge beside it carries seven carved nymphs. The O'sulloc Tea Museum stands in the green tea fields, and the time there is your own: walk the rows, stay for the tea and the desserts. Aewol Cafe Street is the island's best-known sunset spot, with the cafes lined along the coast. A haenyeo session follows, where you meet the divers who keep Jeju's diving tradition going and hear the work described by the women who do it. Admission to it is included in the price, and the money goes back into the tradition. The day ends at Ihotewu Beach, where two lighthouses shaped like horses, one red and one white, stand by the water. Both appeared in the K-drama Welcome to Samdal-ri, and the pocha, the street food stalls, open along the shore as the sun goes. You can finish there, or at Dongmun market, and explore Jeju City on your own. Cancel at least 24 hours before departure for a full refund.
