Bumbilkka shows a 30-day crowd forecast for tourist spots across South Korea.
It is built on open tourism data published by the Korea Tourism Organization,
refreshed once every morning, so you can pick a day when fewer people are there.
[ Main features ]
30-day calendar
- Every place opens as a calendar of the next 30 days.
- Weekdays line up in columns, so busy weekends stand out at a glance.
- The calmest day within the month is called out for you.
- Even for places that are always busy, you see how the day ranks among that
place's own 30 days.
Try these instead
- When the day you picked looks crowded, the app suggests calmer places
in the same province for that exact day.
- It looks in the same district first and favours places people actually
visit on the same trip.
- Where coordinates are known it shows the distance, and skips places too far away.
Off the beaten path
- Calm places in districts the Ministry of the Interior and Safety lists
as population-declining.
- Find somewhere quieter and help a region that needs visitors.
Today and the weekend
- See places forecast to draw the fewest visitors today, and the busy ones.
- Switch to the upcoming weekend with one tap.
Browse by region
- Pick a province and a district, then sort places by how calm they are.
- See the districts weekday visitor pattern from the last four weeks.
Events
- Festivals running now and starting within 45 days.
- Check how crowded the surrounding area is at the same time.
Saved places and reminders
- Save the places you visit often and see them on the home screen.
- Get a daily notification with that days level for your saved places.
[ About the data ]
- Source: Korea Tourism Organization open data (TourAPI / Korea Tourism Data Lab)
and the Ministry of the Interior and Safety population-declining area list
- Updated once a day, around 06:00 KST
- The crowd index is a machine-learned estimate from mobile-network visit patterns.
It is not a live headcount and can differ from what you find on site.
- A level compares a place with its own 30 days, not with other places, and it is not a
visitor count. "Peak" means that place is at its own busiest stretch, not that it is
crowded in absolute terms.
[ Good to know ]
- No sign-up.
- No location permission.
- Saved places and settings stay on your device.
- Free, with ads.
