Gimhae Airport or Busan Station arrival?
For Gimhae International Airport, PUS, save the terminal and compare the Busan-Gimhae Light Rail connection with your hotel route or booked car. Sasang connects the light rail with Metro Line 2. If arriving by KTX at Busan Station, save your final Metro or taxi connection separately. Keep the hotel name and address in Korean beside the map pin so your arrival instructions work for both station navigation and driver pickups.
Metro exits and four Busan stops
Save the line, direction and exit number before boarding. Download your next route for tunnels where signal can dip, and keep your hotel entrance available offline. Prepare Naver Map or KakaoMap before departure and save the Korean place name alongside the English one. Coastal neighbourhoods are spread out, so group nearby visits rather than crossing the city repeatedly between timed bookings.
- Haeundae: choose a specific beach entrance or café for meeting friends and save your route back to the station.
- Gwangalli: keep the exact restaurant or seafront pickup point handy instead of sharing only the beach name.
- Jagalchi Market: save your intended entrance and the walking connection to your next Nampo-area stop.
- Gamcheon Culture Village: keep your arrival point and return bus or taxi route ready before exploring the hillside lanes.
Busan-specific tip: Busan Station for KTX and the Nopo intercity bus terminal are different departure points. Check whether your booking is for a train or bus, then save the exact terminal name and access route.
For Gyeongju or a ferry outing, download the ticket, departure location and return arrangements before leaving your accommodation. On train journeys, keep carriage details accessible offline for tunnels and station changes.
