Korea's Summer Beaches: A 3-Keyword Overview

To help you decide, we have summarized each region with one keyword.

1. The City of Vibrant Nightlife and Festivals: Busan

Busan is a special place where the charms of the sea and a large metropolis coexist. During the day, you can enjoy swimming on the hot sandy beaches, and at night, you can enjoy parties and gourmet food under the brilliant lights of skyscrapers.

2. The Mecca of Surfing and Clear Waters: East Coast

If you prefer clear and deep blue water, the East Coast of Gangwon-do is the answer. It is easily accessible by KTX from Seoul, making it great for feeling the essence of the sea even on short schedules.

• Representative Beaches: Gangneung Gyeongpodae, Sokcho Beach, Yangyang Surfyy Beach

Recommended Guide by Travel Theme

• Couple Travel: We recommend Gwangalli (Busan) for its beautiful nights or Jeju Island for its many aesthetic cafes.

• Family Travel: Hyeopjae (Jeju) or Gyeongpodae (Gangneung) are great for children due to their shallow and safe waters.

• Solo Travel: We recommend Gangneung (East Coast) for relaxing on your own or Yangyang for its active surfing community.

Tips for Korean Beaches: Enjoy Smarter

1. Umbrella & Tube Rental: Most beaches rent out umbrellas and tubes for a fee. Recently, 'card payments' are accepted in most places, but you might need cash at traditional markets or smaller beaches.

2. Shower Facilities: There are public shower facilities near the beaches. The usage fee is usually around 2,000 to 3,000 KRW; it is recommended to bring your own towel and toiletries.

3. Lifeguards: Only swim in areas where lifeguards in red uniforms are stationed. If you see a 'no swimming' flag (usually red), you must never enter the water.

FAQ: Frequently Asked Questions

Q: Is there a large cost difference between Jeju Island, which requires a flight, and Busan/East Coast, which can be reached by train?
A: During the peak season (July–August), flight tickets and car rental costs in Jeju surge significantly. If you want to save your budget, traveling to Gangneung or Busan via KTX can be more economical.

Q: Which place is best for snorkeling?
A: The East Coast (Gangneung, Samcheok) or Jeju Island (Panpo Port, Hamdeok), known for their clear water, are the best places to enjoy snorkeling.
