A dark underground cave in the empty Manjanggul Lava Tube Cave on Jeju Island, South Korea
The impressive Manjanggul Cave is one of the world's longest lava tubes, a geological remnant left behind when lava deep within the ground rises during an eruption. See remarkable lava stalactites 70 centimeters tall and the famous turtle rock formation that some say is shaped like Jeju Island itself. The tunnel takes roughly 50 minutes to explore.
The path to Seongsan Ilchulbong on Jeju Island, South Korea
Formed thousands of years ago by an erupting underwater volcano, Seongsan Ilchulbong (Sunrise Mountain) juts out of the ocean in the shape of a crown. The hike takes 40 minutes (with breaks) and rewards you with a sweeping view of the crater and sparkling east sea.
Island legend has it that seven nymphs descended at midnight to bathe in the waters of Cheonjiyeon Waterfall. With three waterfalls and a deliciously refreshing pool you can swim in, you'll quickly be enchanted. Cruise to Jeju Island and be sure to catch a look at the seven nymphs emblazoned on the Seonimgyo Bridge.
Stop by the Dongmun Market, which sells local delicacies like tender Jeju black pork (made from the highly prized black pigs that inhabit the island), spicy kimchi and even chocolate. The locals also pride themselves on their delicious fresh seafood, piled into a hot pot or served raw, sashimi-style. For the adventurous, try the fresh raw octopus that's still wriggling on your plate.
The Cheju Underground Shopping Street is the perfect place to get all your shopping done during your Jeju Island cruise. Pick up some famous Korean cosmetics, or keep it traditional with Korean dolls and ginseng. Typical souvenirs include mini replicas of Jeju guardian statues and sweet Jeju citrus made into chocolates or teas.
