Beaches like Geumneung and Hyeopjae are popular amongst families with small children because of the shallow and calm waters. Surfing enthusiasts like to go to Jungmun Saekdal Beach for its powerful waves, while coffee lovers choose to go to Woljeong-ri Beach, as it’s lined with dozens of cafes that overlook the clear, turquoise waters. If you’re staying in the city and don’t want to travel too far, there’s even a beach for you, the Iho Tewoo Beach.

RECREATIONAL WATER ACTIVITIES

Besides swimming or lounging on the beach, there is a myriad of other ways to enjoy Jeju’s ocean waters.


 Snorkeling and scuba diving are popular summer pastimes, but if you’re not into swimming and want to stay above waters, there’s something for you, too. You can rent paddleboards or clear bottom kayaks, or if you want a more luxurious experience, there are yacht tours you can take around the island. 


You can also go dolphin watching by boat, or if you want to keep it personal, just rent a whole yacht for yourself.

JEJU’S AUTUMN SEASON: WHIMSICAL AND ROMANTIC

Autumn (September to November) in Jeju is quite beautiful and perfect for romantics. As hot summer days cool down, the temperature gets wonderfully pleasant, and you can enjoy mild days still bright with sunshine. 


The fall is the perfect season to visit oreum, the iconic volcanic cones of Jeju Island, as many are covered in fields of swaying silver grass. Pink muhly is another grass that grows in the fall, and the fluffy pink plant has become a popular photo backdrop.
