Hagosudong Beach

Located on Udo’s eastern coast, this beach is considered one of the island’s most beautiful swimming spots. With emerald-blue water and a dazzling white sandy shore, it offers an exotic seaside landscape, and the shallow, crystal-clear water along the beach is ideal for enjoying the sea. The bright sand—formed by accumulated fragments of broken coral—creates Udo’s distinctive coastal scenery.

Nearby, you’ll find cafés, restaurants, and places to relax, and it’s also a great area to explore on foot or by bicycle along Udo’s coastal road. On clear days, you can even see Seongsan Ilchulbong and views of Jeju Island, making it a popular photo spot. It’s one of Udo’s 대표 관광지 where you can enjoy both beautiful ocean views and a laid-back atmosphere.
