Hi Christy,
Thanks for your note. Well... looking around the city these days, the trees are definitely turning. I think I'll have to make a trip up to Mt. Gwanaksan some day very soon. I'd hate to miss what's got to be one of the most spectacular views of crimson, orange and yellow hillsides in the city! Hope you'll write again.

Best, Matt

Hi Atul,
As you might guess, this is hard to predict. However, in my experience, early-to-mid October is always a lovely time to be here. The weather should be quite pleasant. In terms of seeing fall foliage, the Seoul area typically sees its first autumn color in mid-October with peak color occurring by the end of the month or the first week of November. Here's last year's post to give you a more detailed look. So if you can delay your trip to the week of Oct. 17, that seems like a better bet. Also, if it's too early in Seoul, Mt. Seoraksan in Gangwon Province typically sees color about a week or two before Seoul... but beware of the autumn crowds. Its a gorgeous mountain and national park, but VERY popular for leaf viewing.
Have fun! Best, Matt

Hi Mia,
Yes, late Oct to early Nov should be perfect! In terms of your friend's schedule, I think you're right that it would probably coincide with exams...
