March: Hiking in Spring Flowers

The weather in South Korea starts turning warm in March (0 to 13℃; 32 to 55℉), and springtime flowers are starting to bloom. Though it is still colder in the mountainous area, March in South Korea is a dry month suitable for outdoor activities to find some clues about spring.

Why not visit some national parks on a spring hike during your March trip to South Korea? Jirisan, Hallasan, and Seoraksan National Park are some perfect places for exploring flora and fauna.

As the first Autumn month, the early fall foliage season comes in late September. So, head to Seoraksan National Park for a leisurely hike if you want to capture the changing colors.

September also offers one of the chances to see the brilliantly lit Gyeongbokgung at night, best for a hanbok sightseeing while taking some photos.

October: Autumn Leaves

Though the daytime temperatures are still mild with the sunny days in October (around 20℃, 68℉), there will be a quick drop in the rural and mountainous areas at night (10℃, 50℉), making October one of the best times to see fall foliage in northern Korea.

It will be comfortable to walk around outside with just a sweatshirt and jeans in the first two weeks, while packing well during your late November trip to Korea, especially at night.

Apart from the autumn leaves, chrysanthemums are also blooming this month. And in these chilly days, it is also a perfect time to try some hot and steamy food in Korea. Korean Barbeque with Soju is one of the perfect collocations in winter. And don't miss the army stew (a Korean-type hot pot), tteokbokki (stir-fried sticky rice cakes), and grilled gopchang (cow bowel).
