We know that no two sightseers are the same, that's why we offer two pass options. For those who want to see as much as possible, we've got All-Inclusive passes. Choose how many days you want your pass to be valid for, and then visit as many attractions as you wish.

And for those of you who are a little pickier, we've got the Explorer Pass. With this pass, you can select how many attractions you wish to visit, and you'll then have 60 days to do so. Plus, there's no need to decide which ones you'll visit before you purchase, so you'll still be able to keep your plans flexible.

The Go City app is your key to exploring Seoul. Download for free to your Apple or Android device and then follow the instructions in your confirmation email to sync your pass to the app. Once you arrive in Seoul, all you've got to do is show your pass at each attraction - easy.

Plus, we've loaded the app with plenty of useful attraction info to make planning and exploring even easier.
