  • A solid choiceI had a good experience with OneTravel while booking my family vacation. The price was right, and we could get seated together. The only issue I faced was with the payment processing, but their support team was quick to assist. Overall, a solid choice for travel planning.

Seoul is the capital and largest metropolis of the Republic of Korea (also known as South Korea). This riverside city along the Han River is the anchor of the Seoul Capital Area and includes the adjacent Incheon metropolis and Gyeonggi province. Founded in 18 BC, Seoul is home to a profound history and culture, the best of which is seen in its art, architecture, Buddhist temples, street food culture and vibrant nightlife. It has hosted some iconic sport events like the 1986 Asian Games, 1988 Summer Olympics, and the 2002 FIFA World Cup. The city is home to 115 museums, none more famous than mid-20th century ‘The National Museum of Korea’ that is home to 220000 artefacts.

This number includes plants from 228 species of trees, shrubs and flowers found in and outside Korea. Seoullo 7017 is named thus because the flyover was opened to the public in 1970 and has 17 walkways connected to it.

Best Time to Visit Seoul
