Adventure is waiting just around the corner at Halla Arboretum. It's one attraction you'll find on many visitors' to-do lists. Jeju Loveland and the Paradise Casino are also not far away and worth a pit stop.
The greatest part about having your own rental car is that you can go where you want, when you want. Make the most of your newfound freedom by checking out all there is to do in Hallim. After all, it's only 17 miles away. Hallim Park ought to be high up on your list here. Hyeopjae Beach and the Osulloc Tea Museum are interesting attractions too. The locals will also likely point you in the direction of Pyoseon, 18 miles away. If you've only got time for one thing here, let it be Trick Art Museum. (But we're also big fans of Seongeup Folk Village and the Jeju Horse Park.)
