Geoje Island, Korea’s second-largest island, is a coastal paradise with stunning beaches, dramatic cliffs, and a rich history. Its crown jewel, Oedo Botania, is a private botanical garden accessible only by ferry, boasting meticulously maintained gardens and breathtaking ocean views.

7. Uleungdo Island, Gyeongsangbuk-do 🌋🌊

For the adventurous spirit, Uleungdo Island is a volcanic marvel rising from the East Sea, offering rugged coastlines, pristine waters, and unique marine life.

A UNESCO World Heritage site, Andong Hahoe Folk Village is a living museum that preserves the traditional architecture and culture of the Joseon Dynasty. It’s famously shaped by the winding Hahoe River and is unique because it’s still inhabited by descendants of the original Ryu clan, giving it an authentic, lived-in feel.

10. Muju Deogyusan National Park, Jeollabuk-do ⛰️🌲

For nature lovers seeking cooler climes during the summer, Muju Deogyusan National Park is an ideal escape.

• Tip: Pack layers, as mountain temperatures can be cooler even in summer. Check the cable car operation times.

11. Gyeongju Namsan (South Mountain), Gyeongju 🏞️🗿

While Gyeongju is a popular historical city, its Namsan (South Mountain) is a sprawling outdoor museum that requires more dedicated exploration than just visiting temples. It’s dotted with countless Buddhist relics, including ancient pagodas, Buddha statues carved into rocks, and temple ruins, often hidden amidst lush forests and streams.

• Tip: Combine your visit with a trip to the nearby Chuam Chotdaebawi Rock, a unique candle-shaped rock formation near the coast.

Tips for Traveling to Korea’s Hidden Gems in Summer ☀️

Venturing off the well-trodden path requires a bit more planning, but it’s incredibly rewarding. Here are some tips for your 2025 summer adventure:

• Transportation: While major cities have extensive subway systems, you might rely more on intercity buses (Express Bus Terminal or Dong Seoul Bus Terminal in Seoul) or trains (KORAIL) to reach these smaller towns. Once there, local buses, taxis, or renting a car (especially convenient for Geoje, Ganghwado, or Muju) might be necessary.
• Language: English might not be as widely spoken in these rural areas. Consider downloading a translation app (like Papago or Google Translate) and learning a few basic Korean phrases. “Annyeonghaseyo” (Hello), “Gamsahamnida” (Thank you), “Eolmayeyo?” (How much is it?).
• Accommodation: Options might be fewer than in big cities. Look for guesthouses (pension), traditional hanok stays, or local motels. Booking in advance is highly recommended, especially for summer weekends.
• Internet & Maps: Purchase a local SIM card or rent a pocket Wi-Fi device. Naver Maps or Kakao Maps are generally more accurate for navigation in Korea than Google Maps.
• Cash: While cards are widely accepted, it’s always good to carry some cash for smaller eateries or local markets.
• Stay Hydrated & Sun Protected: Summer in Korea can be hot and humid. Drink plenty of water, wear light clothing, apply sunscreen, and use a hat or umbrella.
