The Seoul Metropolitan Government announced on Monday that it will launch an application providing details on the Seoul Trail on Apple Store and Google Play.
The Seoul Trail is a 157-kilometer-long trail that extends through the mountains and urban streets of Seoul in a circular route. It is split into eight sections with each route clearly marked.
Smartphone users who enter within the 50-meter radius of a Seoul Trail stamp mailbox with their phones' GPS on automatically get a stamp in the application. Those who gather all 28 stamps up for grabs can get a badge and a certificate verifying that they’ve finished walking the Seoul Trail.

With the latest application, those walking the trail can easily find key sights and bathrooms facilities and get help in the event of emergency.
