Seoul on a Rainy Day: An Itinerary That Stays Indoors

Seoul has a proper rainy season and it does not drizzle, it pours. A day built so that the walking between places is underground or under cover.

Reality check

Korean rain in summer is not the intermittent grey of northern Europe. It arrives as a wall of water, lasts hours, and makes the ten-minute walk between two indoor places the worst part of the day. A rainy-day plan is therefore not a list of indoor attractions. It is a route where the gaps between them are also covered.

The real design problem

Anyone can name an indoor museum. The skill is stringing several together with subway exits that come up inside the building, underground shopping streets that run for blocks, and department stores you can cross without going outside. Seoul is unusually good at this once you know it exists.

A day that works

  1. Start at a large national museum. They are enormous, they take a proper half day, and the subway station connects almost directly.
  2. Eat inside. Museum restaurants in Seoul are better than the category suggests, and leaving to find lunch is where a rainy day falls apart.
  3. Move to an underground shopping street in the afternoon. These run for city blocks beneath the main roads and are a genuine part of Seoul rather than a fallback.
  4. Finish in a covered market or a department store food hall for dinner.

Other indoor options worth the trip

Why it works in rain
Large national museumsHalf a day each, subway-connected, free or cheap
A cave or mine attraction outside the cityUnderground by definition; the weather is irrelevant
The botanic glasshouseGreen and warm while it pours outside
An aviation or science museumMade for a long indoor day, and good with children
Covered traditional marketsRoofed, chaotic, and better in bad weather than good

Umbrella logistics

Convenience stores sell umbrellas everywhere for very little, so do not carry one for three days on the chance. Shops and museums have plastic sleeves or umbrella stands at the door, and using them is expected rather than optional.

What to move to another day

  • The palaces. They are mostly outdoor courtyards, and hanbok rental in heavy rain is miserable.
  • Mountain and tower viewpoints. The view is the point and there will not be one.
  • The river parks and anything on a bicycle.
  • Outdoor markets and street-food alleys, as opposed to covered ones.

In the rainy season, check the forecast for the day, not the week

Korean summer rain often arrives and clears within the same day. A morning that looks unsalvageable can turn into a clear evening, so keep an outdoor option ready rather than writing the whole day off.

+When is the rainy season?

Broadly early summer, though it has become less predictable. Typhoon remnants can bring heavy rain into early autumn.

+Do things close in heavy rain?

Indoor attractions do not. Outdoor markets thin out and mountain trails and cable cars can close in a storm.

+Is the subway affected?

Rarely. It is the most reliable thing in the city in bad weather, which is why this itinerary is built on it.
